Versiv 2 Cabling Certification Product Family Users Manual Fiber Tests with Two Main Testers If you have two main testers, you can use FiberInspector video probes at both ends of the cabling for faster inspections of fiber endfaces. You can also use the second main tester as a remote tester for loss/length tests with CertiFiber Pro modules. To use a main tester as a remote Tap TOOLS then tap Main as Remote. 94 Chapter 6: Certify Fiber Cabling WWarningX* Before you use the tester, read the safety information that starts on page 5. Overview of Features The Fluke Networks CertiFiber® Pro Optical Loss Test Set (OLTS) modules attach to Versiv™ 2 main and remote units to make rugged, hand-held testers that let you certify, troubleshoot, and document optical fiber cabling installations. The testers include these features: Measures optical power loss and length on dual-fiber, multimode cabling at 850 nm and 1300 nm (CFP-MM) or on dual-fiber singlemode cabling at 1310 nm and 1550 nm (CFP-SM). The four-wavelength module (CFP-QUAD) measures at 850 nm, 1300 nm, 1310 nm, and 1550 nm. Interchangeable connector adapters on input and output ports let you make reference and test connections that agree with ISO standards for most SFF (small form factor) connectors. Visual fault locator helps you find breaks, bad splices, and bends and verify fiber continuity and polarity. Optional FiberInspector™ video probe lets you inspect fiber endfaces and save the images in test reports. You can save approximately 30,000 fiber test results in the tester’s internal memory. You can save more results on a removable flash drive. 95 Versiv 2 Cabling Certification Product Family Users Manual Connectors, Keys, and LEDs W* BV123.EPS Figure 40.

Chapter 6: Certify Fiber Cabling Requirements for Reliable Fiber Test Results Requirements for Reliable Fiber Test Results To get reliable fiber test results and make sure your tester meets its accuracy specifications, you must use the correct procedures: Use proper cleaning procedures to clean all fiber connectors before every use. See Chapter 4. Set the reference frequently. See “About the Reference for Fiber Tests” on page 106. Use only test reference cords that comply with ISO/IEC 14763-3. Measure the loss of the cords frequently. See “About Test Reference Cords and Mandrels” on page 108. For multimode fiber, make sure you use the encircled flux test reference cords (EF-TRCs) or standard mandrels correctly. See “About the EF-TRC (Encircled-Flux Test Reference Cords)” on page 108 and “TRCs Necessary for Links with APC Connectors” on page 111. Keep the tester’s software current. The latest software is available on the Fluke Networks website. See “Update the Software” on page 243. Make sure you select the correct fiber type and test limit for the job, and the index of refraction for the fiber is correct. See Table 6 on page 113. Make sure the battery is fully charged. Send the modules to a Fluke Networks service center every 12 months for factory calibration. 105 Versiv 2 Cabling Certification Product Family Users Manual About the Reference for Fiber Tests The reference procedure for fiber cable sets a baseline power level for loss measurements. If the power level that enters the fiber from the source changes, the reference and your loss measurements will be incorrect. The power level can change, for example, when the temperature at the job site increases or decreases or when you disconnect then reconnect a test reference cord at the tester’s output port. So, it is important to set the reference frequently. When to Set the Reference Note At the job site, turn on the testers and let them sit for a minimum of 5 minutes before you set the reference. Let them sit longer if they are above or below ambient temperature. The tester requires you to set the reference at these times: When you change the CertiFiber Pro module in the main or remote tester. When you use a different remote tester. When you change the Reference Method in the test setup. Set the reference also at these times: 106 At the start of each day, at the job site, then at regular intervals during the day. For example, set the reference when you start tests on a different series of fibers. When you connect a test reference cord to the module’s output port or to another source, even if you connect the same test reference cord you connected before. When the tester tells you that the reference is out of date. When a loss measurement is negative. This occurs when there was a problem when you set the reference. For example, an endface was dirty or the testers were cold. Chapter 6: Certify Fiber Cabling Requirements for Reliable Fiber Test Results WCaution Do not disconnect the test reference cords from the modules’ output ports after you set the reference. If you do, you will change the amount of optical power that enters the fiber and the reference will not be correct. Good Reference Values For Smart Remote and Loopback modes, these are the typical ranges for reference values: Multimode 50/125 μm fiber: -19.4 dBm to -26.5 dBm Multimode 62.5/125 μm fiber: -17.5 dBm to -23.0 dBm Singlemode fiber: -1.0 dBm to -6.0 dBm For Far End Source mode with a CertiFiber Pro source, reference values must be in these ranges: Multimode 50/125 μm fiber: -19.4 dBm to -26.5 dBm Multimode 62.5/125 μm fiber: -17.5 dBm to -23.0 dBm Singlemode fiber: -1.0 dBm to -9.7 dBm If your reference value is outside of the applicable range given above, clean and inspect all connectors then set the reference again. Do this even if the tester lets you use the value. If your test reference cords and connectors are in good condition, and you use the correct procedure to set the reference, the reference value will not change by more than approximately 0.4 dBm. How to See the Reference Values After you set the reference, tap View Reference on the SET REFERENCE screen. After you do an Autotest, tap the result window for a fiber, then tap VIEW REFERENCE. 107 Versiv 2 Cabling Certification Product Family Users Manual About Test Reference Cords and Mandrels Use only test reference cords (TRCs) that have low loss: Maximum loss for multimode TRCs: 0.15 dB Maximum loss for singlemode TRCs: 0.25 dB To make sure your test results are accurate as possible: Inspect the endfaces of the TRCs every 24 to 48 tests and clean them when necessary. Use the TRC VERIFICATION wizard available for the 1 Jumper and 3 Jumper reference methods to measure the losses of the TRCs. The losses of the TRCs are included in the loss measurements for links, so you must make sure the losses are very small. The wizard saves the results of the TRC tests to show that your TRCs were good. IDs for these results start with “TRC”, show the date and time of the test, and have an for the test result. About the EF-TRC (Encircled-Flux Test Reference Cords) The CFP-MM and CFP-QUAD kits includes the EF-TRC (encircled flux test reference cords), which have signal conditioners on the cords. When you use the EF-TRCs with the CertiFiber Pro multimode modules, your tester complies with IEC 61280-4-1, ISO/ IEC 14763-3, and TIA-526-14-B standards for encircled flux. Measurements made with compliant equipment change less than 10 % for losses of 1 dB or more when you make them at different times or with different equipment that is also compliant. Note The IEC 61280-4-1, ISO/IEC 14763-3, and TIA-526-14-B standards require your optical loss test set to comply with encircled flux standards at 850 nm with 50 µm/125 µm fiber. The standards recommend compliance at 850 nm with 62.5 µm/ 125 µm fiber and at 1300 nm with 50 µm/125 µm and 62.5 µm/125 µm fiber. 108 Chapter 6: Certify Fiber Cabling Requirements for Reliable Fiber Test Results WCaution To prevent damage to fiber connectors, to prevent data loss, and to make sure that your test results are as accurate as possible: Use the EF-TRC cords only with the CertiFiber Pro modules or with sources approved by Fluke Networks for use with the cords. If a source does not have the correct LED and internal fibers, the EF-TRC cords will not make launch conditions that agree with encircled flux standards. When you use the EF-TRCs, DO NOT use other mandrels. Always follow the handling guidelines given in Figure 44. Put protective caps on all connectors when you do not use them. Use EF-TRCs that have the fiber core dimension (50 µm or 62.5 µm) and type of connectors (SC, ST, LC, or FC) that are the same as the fiber link. Do not use EF-TRCs with hybrid patch cords to connect to links that have other types of connectors. Minimum bend diameter: 1.2 in (30 mm) GPU157.EPS Figure 44. How to Prevent Damage to the EF-TRC Fiber Cables 109 Versiv 2 Cabling Certification Product Family Users Manual About APC Connectors When you do tests on links with APC (angled physical contact) connectors, use only test reference cords with APC connectors on the ends connected to the link. If you connect non-APC connectors to the link, the connectors will cause large reflections that make loss measurements inaccurate. For tests on links with APC connectors, use test reference cords that also have APC connectors on the ends connected to the tester’s input ports. This is necessary for the 1 jumper reference method. You can connect APC connectors to the tester’s input ports because the fiber does not touch the lens on the input port. Note Do not connect APC connectors to the tester’s output ports. APC connectors will not damage the ports, but they will not receive enough optical power from the tester because the output ports are designed for UPC connectors. Figure 45 shows the TRCs necessary for tests on links with APC connectors. 110 Chapter 6: Certify Fiber Cabling Requirements for Reliable Fiber Test Results UPC Note Connect only UPC connectors to the tester’s output ports UPC APC UPC APC APC APC APC APC APC APC APC APC APC APC UPC Reference APC APC APC APC APC UPC TRC Verification APC UPC Fiber Link Test *Use the EF-TRCs only with multimode modules. BV166.EPS Figure 45. TRCs Necessary for Links with APC Connectors 111 Versiv 2 Cabling Certification Product Family Users Manual About Standard Mandrels Standard mandrels make measurements of multimode power loss more reliable than if you use no mandrels, but the measurements do not comply with the standards for encircled flux. Fluke Networks recommends that you always use only the EF-TRCs with the CertiFiber Pro multimode modules so that your measurements comply with EF standards. If you must do tests in Far End Source mode with a different multimode source, and the source is not approved by Fluke Networks for use with the TRCs, use standard mandrels. Make sure you use the size of mandrel that is correct for 50 μm or 62.5 μm fiber, and read all instructions for the source and mandrel. WCaution If you use mandrels for tests on multimode fiber, do not use test reference cords made from bendinsensitive fiber. The mandrels possibly will not remove all of the modes that can make your loss measurements unreliable. Settings for Fiber Tests Table 6 gives descriptions of the settings for fiber tests. To set up a project, which includes the settings in Table 6, cable IDs, and operator names, see Chapter 11. To set up a fiber test On the home screen, tap the test setup panel. On the CHANGE TEST screen, select a fiber test to change, then tap EDIT. Or to set up a new fiber test, tap NEW TEST. If no module is installed, the MODULE screen shows.

To use a different IOR, make a custom fiber type. See the Technical Reference Handbook. -continued- 113 Versiv 2 Cabling Certification Product Family Users Manual Table 6. Settings for Fiber Tests (continued) Test Limit Select the correct test limit for the job. To see a different group of limits, tap MORE, then tap the name of a group. To make a custom limit, tap Custom in the Limit Groups list. See the Technical Reference Handbook. Reference Method On the No. of Connectors/Splices screen, set the number of jumpers you will use in each fiber path when you set the reference. The dotted lines in the diagram on the screen show you which parts of the link are included in the test results. The number of jumpers you use has these effects on loss measurements: 1 Jumper: Loss measurements include the connections at both ends of the link. The figures in this manual show 1 Jumper connections. 2 Jumper: Loss measurements include one connection at one end of the link. 3 Jumper: Loss measurements do not include the connections at the ends of the link. The tester measures only the loss of the fiber. This setting does not change the loss measurements, but it can change the PASS/FAIL result for test limits that use a calculated loss limit. For all test limits, the tester saves this setting to show the reference method you used. WCaution Most cable manufacturers will give you a warranty on a fiber installation only if you use the 1 Jumper reference method when you certify the installation. Note Different standards use different names for the three methods. See Appendix A. 114 Chapter 6: Certify Fiber Cabling Settings for Fiber Tests Table 6. Settings for Fiber Tests (continued) Connector Type Select the type of connector, such as SC or LC, used in the cabling. The tester uses this setting when you do bi-directional tests. If you select a connector that has a threaded or bayonet coupler, such as FC or ST, the tester waits for you to confirm that the connection is complete before it starts the second part of the test. If you select a quickrelease connector, such as SC or LC, the tester automatically starts the test when you connect the fiber. The tester also saves this setting to record the type of connector you used. This setting does not change your test results or any of the diagrams that the tester shows. If the correct type is not in the list, select General. 115 Versiv 2 Cabling Certification Product Family Users Manual Table 6. Settings for Fiber Tests (continued) No. of Connectors/ Splices The Total Connections and Splices settings are applicable only if the selected test limit uses a calculated limit for loss. Total Connections: Enter the total number of connections that are in each path of the link. Do not adjust the number for the Reference Method you use. For example, if the link has 3 connections, enter “3” even if you use the 2 or 3 Jumper reference method. When the tester calculates the loss limit, it automatically removes the losses of the connections you used to set the reference. Note The CertiFiber Pro automatically adjusts the number of connections for the Reference Method you use. This is different from the DTX CableAnalyzer, where you do not include the reference connections in the number of connectors. Splices: Enter the number of splices in each path of the link. Jumper Reference: Enter the number of jumpers you will use in each fiber path when you set the reference. The dotted lines in the diagram on the screen show you which parts of the link are included in the test results. See Reference Method above. Figure 46 shows the No. of Connectors/Splices screen. Figure 47 shows how to count the jumpers, connectors, and splices for this setting. TRC LENGTH (Test reference cord length) 116 You can enter length of your test reference cords when you set the reference. To enter this value, tap TRC LENGTH on the SET REFERENCE screen. The length you enter does not change the test results. The tester saves the length with the results to meet TIA reporting requirements. Chapter 6: Certify Fiber Cabling Settings for Fiber Tests GPU140.EPS Figure 46. Screen to Set the Number of Connectors, Splices, and Jumpers Total Connections: Enter the total number of connections that are in each path of the link. Do not adjust the number for the Reference Method you use. For example, if the link has 3 connections, enter “3” even if you use the 2 or 3 Jumper reference method. When the tester calculates the loss limit, it automatically removes the losses of the connections you used to set the reference. Note For links with MPO modules, each module is one connector. 117 Versiv 2 Cabling Certification Product Family Users Manual Splices: Enter the number of splices that are in each path of the link.

How to Count the Numbers of Connectors, Splices, and Jumpers 119 Versiv 2 Cabling Certification Product Family Users Manual About 1 Jumper Reference Connections The reference and test connections shown in this manual give 1 jumper results. 1 jumper results include the loss of the fiber plus the loss of the connections at both ends of the link. This is the best method for tests on premises fiber installations. Premises installations typically use patch cords at both ends of the link, and connector loss is a large part of the total loss. If you do not have the correct connector adapters, see Appendix B for other connections that give 1 jumper results. For descriptions of the 2 and 3 jumper reference connections, see the Versiv 2 Technical Reference Handbook. WCaution Most cable manufacturers will give you a warranty on a fiber installation only if you use a 1 Jumper reference when you certify the installation. Note If you use a 2 Jumper reference, the Wizard for the reference procedure does not show steps for the TRC verification. To save test results for the TRCs, do the tests manually. 120 Chapter 6: Certify Fiber Cabling Autotest in Smart Remote Mode Autotest in Smart Remote Mode Use Smart Remote mode to do tests on dual-fiber cabling. In this mode, the tester measures loss and length on two fibers at two wavelengths. If you turn on the Bi-Directional function and swap the fibers halfway through the test, the tester makes measurements in both directions. Figure 48 shows the equipment for tests in Smart Remote mode. Fiber Tests with Two Main Testers If you have two main testers, you can use one as a remote tester for tests in Smart Remote mode. This also lets you use FiberInspector video probes at both ends of the cabling for faster inspections of fiber endfaces.

Overview of Features The OptiFiber® Pro Optical Time Domain Reflectometer (OTDR) module attaches to a Versiv™ 2 main unit to make a rugged, hand-held tester that lets you locate, identify, and measure reflective and loss events in multimode and singlemode fibers. Typical maximum test ranges are 35 km maximum at 1300 nm for multimode fiber and 130 km maximum at 1550 nm for singlemode fiber. The tester includes these features: Automatic analysis of OTDR traces and events helps you identify and locate faults on multimode (850 nm and 1300 nm; 50 μm and 62.5 μm) and singlemode (1310 nm and 1550 nm) fiber. Shows OTDR results as an intuitive map of events, a table of events, and an OTDR trace. Automatic bi-directional averaging gives you more accurate loss measurements than measurements made in one direction. Gives a PASS or FAIL result based on a test limit that you specify. “Document Only” test limit is available if PASS/FAIL results are not necessary. Touchscreen lets you quickly navigate through different views of the results and see more information about events. SmartLoop™ test: One test gives you OTDR results for both fibers in a link. 149 Versiv 2 Cabling Certification Product Family Users Manual DataCenter OTDR™ test gives optimal performance when you do tests on fiber installations that have short links, many connections, and possibly large reflections. FaultMap™ test lets you make maps of your cable plant, see patch cords as short as 0.5 m, and see events that have poor reflectance. Visual fault locator helps you verify the continuity of fibers and locate faults in fibers and connectors. Optional FiberInspector™ video probe lets you inspect fiber endfaces and save the images in test reports. Saves approximately 2000 OTDR tests on fiber links with an average length of 2 km, and up to 5000 tests for lengths less than 2 km. Connectors, Keys, and LEDs See Figure 58.

The tester shows only the test limits and wavelengths that are applicable to the selected fiber type. 158 Chapter 7: Use the OTDR Settings for OTDR Tests Table 7. Settings for OTDR Tests (continued) Fiber Type Settings IR: The tester uses the index of refraction to calculate the optical length of the fiber. Each fiber type includes the value specified by the manufacturer. To use a different IR, make a custom fiber type. See the Technical Reference Handbook. Backscatter: Backscatter is the backscatter coefficient. The tester uses this value to calculate the reflectance of events for OTDR tests and the overall ORL for the link. Each fiber type includes the value specified by the manufacturer. To use a different backscatter value, make a custom fiber type. See the Technical Reference Handbook. Test Limit Select the correct test limit for the job. Generic limits, such as General Fiber and Document Only, let you do tests when no industry-standard limit is applicable and you do not want to make a custom limit. These limits are in the Miscellaneous group. To see a different group of limits, tap MORE, then tap the name of a group. Some test limits use the measured length of the fiber to calculate a limit for loss. Test Limit Settings This item shows only if the selected test limit calculates a loss limit for each link. For such limits, enter the number of connectors and splices in the link. See the Technical Reference Handbook. 159 Versiv 2 Cabling Certification Product Family Users Manual About Launch and Tail Cords Launch and tail cords let the tester measure the loss and reflectance of the first and last connectors in the cabling and also include them in the measurement of overall loss. Without launch and tail cords, no backscatter is available before the first connector nor after the last. To measure the properties of a connector, the tester must measure the backscatter before and after the connector. Fluke Networks recommends that you use launch and tail cords. You should also use the launch/tail cord compensation function to remove the lengths of these fibers from the OTDR measurements. If you select a test limit that requires you to use launch and tail cords, the tester shows a warning message when you try to do an OTDR test without launch and tail cords. WCaution For tests on cabling that has angled physical contact (APC) connectors, use only launch/tail cords that have APC connectors at the ends connected to the cabling. Other connector types cause large reflections that can cause unreliable test results. Notes Do not use hybrid patch cords to connect the launch or tail cords to the cabling under test. Use launch and tail cords with the correct connectors to connect directly to the cabling under test. This gives the best measurement of the first and last connectors in the link. Launch and tail cords with different types of connectors are available from Fluke Networks. Launch + Tail compensation usually gives the most accurate measurements. The style of the case for your launch/tail cords can be different from the cords shown in this manual. 160 Chapter 7: Use the OTDR About Launch and Tail Cords How to set up the launch compensation function Select launch and tail cords that have the same type of fiber as the fiber you will test. On the home screen, tap the test setup panel. On the CHANGE TEST screen, select an OTDR test to change, then tap EDIT. Or to set up a new OTDR test, tap NEW TEST then tap Auto OTDR, Manual OTDR, or DataCenter OTDR. On the TEST SETUP screen, tap the Launch Compensation control to set it to On. On the TEST SETUP screen, make sure the Fiber Type is correct. Change it if necessary. On the TEST SETUP screen, tap SAVE. On the home screen, tap the TOOLS icon, then tap Set Launch Compensation. On the SET LAUNCH METHOD screen tap the type of compensation you want to do. Clean and inspect the OTDR port and the launch/tail cord connectors. Make the connections for the type of compensation you selected, as shown on the SET LAUNCH METHOD screen. 10 Tap SET. 11 When the SET LAUNCH COMP screen shows, select the event or events that are the end of the launch cord and the start of the tail cord (if you used a tail cord). 12 Tap SAVE. Figure 71 shows an example of an OTDR trace with launch and tail markers enabled. Note If you change the launch or tail cord, do the compensation procedure again. 161 Versiv 2 Cabling Certification Product Family Users Manual How to Prevent Damage to the Launch Cord Connectors When you do not use a launch cord, keep the connectors attached to the case or inside the case. See Figure 61. Cords in a zippered case WCaution Do not make tight bends in the fibers. Cords with a mechanical reel GPU44.EPS Figure 61. How to Prevent Damage to the Launch Cord Connectors How to Hang the Launch Cords The optional TPAK magnet and strap let you hang the launch cords from metal surfaces (Figure 62). 162 Chapter 7: Use the OTDR OTDR Port Connection Quality Figure 62. How to Use the Optional TPAK Magnetic Hanger GPU191.EPS OTDR Port Connection Quality When you do an OTDR test, the test shows the quality of the OTDR port connection (Figure 63). If a test takes more than approximately 3 seconds, the PROGRESS screen also shows a preview of the OTDR trace. The trace is black for one wavelength and blue for the other wavelength. If the gauge is not in the Good range Clean the OTDR port and the fiber connector. Use a video probe to inspect the endfaces in the port and fiber connector for scratches and other damage. If an endface on the tester shows damage, contact Fluke Networks for service information. 163 Versiv 2 Cabling Certification Product Family Users Manual If the gauge stays outside the Good range, remove the adapter from the module and inspect the adapter for damage. Make sure that the white plastic ring inside the center tube shows no damage. A poor OTDR connection increases the dead zone at the connector. The dead zone can hide faults that are near the OTDR connector. A poor connection also decreases the strength of the signal from the OTDR. The weaker signal causes more noise on the trace, which can cause the OTDR to miss events. It also decreases the dynamic range. When the test is completed, the quality gauge shows in the details for the OTDR Port event on the EventMap screens. The tester includes the gauge with the test results you save. GPU17.EPS Figure 63. The OTDR Port Connection Quality Gauge and Progress Screen 164 Chapter 7: Use the OTDR How to Do an OTDR Test How to Do an OTDR Test Figure 64 shows the equipment for OTDR tests. To do an OTDR test Make sure that the home screen shows the correct settings for the job. If it is not necessary to use specific settings, set the test type to Auto OTDR to make sure the results show all of the events on the fiber. Clean and inspect the connectors on the launch and tail cords and the fiber to be tested. Connect the tester to the link as shown in Figure 65, 66, or 67. Tap TEST or press . Note The tester shows a warning if there is an optical signal on the fiber.
