2 Introduction Page 15 2. INTRODUCTION 2.1. PURPOSE Cellular telephone systems transmit signals in two directions between a base transceiver station (BTS) and mobile stations (MS) within the signal coverage area. If weak signal transmissions occur within the coverage area because of indoor applications, topological conditions or distance from the transmitter, extension of the transmission range can be achieved by means of an optical distribution system. Such a system contains an optical Master Unit and several Remote Units. The number of the Remote Units depends on the hardware and software configuration. The Remote Units are connected to the Master Unit with optical links. The optical loss must be less than 10 dB inclusive optical couplers or splitters. The Master Unit is the connection to the base transceiver stations. The configuration of a Master Unit depends on the number of the Remote Units and the frequency range. The optical transmission uses WDM-systems with a wavelength of 1550 nm in the uplink and 1310 nm in the downlink. 2.2. THE ION™-M7P/85P/17P/19P (INTELLIGENT OPTICAL NETWORK; MMR) The ION-M7P/85P/17P/19P transports signals on the RF layer in a way that multiple operators and multiple technologies are moved simultaneously from a cluster of base stations to a remote location over the same fiber. The ION optical distribution system provides a coverage solution for dense urban areas, tunnels, subway, airports, convention centers, high-rise buildings and other locations where physical structures increase path loss. It has been specifically designed to reduce zoning problems and to provide homogeneous coverage. The compact, mechanical design is specifically architected to mount inside of poles or along side structures in such a way that it has a minimal visual impact. The ION-M7P/85P/17P/19P is available in single or multi-band configuration supporting 700 MHz, 850 MHz, 1700 MHz/ 2100 MHz and 1900 MHz in parallel. It has been specifically tested and optimized for LTE, iDEN, GSM, EDGE, CDMA2000, EV-DO, WCDMA, HSPA+, and OFDMA. Furthermore, it is provisioned for future improvements to the modulation and frequency bands. In addition it is backwards compatible to legacy standards such as TDMA and Analog.
User’s Manual for ION™-M7P/85P/17P/19P (ML-Cab) Page 16 MF0143AUA.doc The ION is easily set-up and supervised via a graphical user interface (GUI). Remote units can be commissioned through the use of built-in test equipment. An auto-leveling function compensates for the optical link loss making installation easy and quick. The entire system may be monitored remotely via an Andrew OMC. This platform uses SNMP protocol and is compliant to X.733 standard. Should a sophisticated interface not be required, the Master Unit can be directly connected to the alarm interface of a base station via its contact relay. Multi-channel, multi-operator support Reduced visual impact form factor Efficient, high power amplifier Single fiber for multiple bands and multiple remotes Comprehensive operations and management system for configuration and alarming OMC with SNMP according to X.733 standard Easy installation and commissioning

For the power supply breaker, observe the following recommendation: 120 Volt / 20 Amp max. or 240 Volt / 16 Amp, single-phase, 50 / 60 Hz AC service is needed, i.e. the external AC breaker should be 20 Amps max. for 120-Volt service or 16 Amps for 240-Volt service. For the DC power supply, observe the local regulations of the DC service provider. 3.5. OPTICAL-FIBER-CABLE CONNECTION - RULES Main optical system parameters: Fiber: Single mode fiber, type is E9/125 µm Attenuation: <0.36 dB / km @ 1310 nm / <0.26 dB / km @ 1550 nm Dispersion: <3.5 ps / nm km @ 1310 nm / <18.0 ps / nm km @ 1550 nm Fibre-cable connectors E2000APC8° ION-M system: The specified bending radius ( < 4 cm) of the optical fibers must not be exceeded. The pigtails for the connection between Master Unit and Remote Unit must have a sufficient length. A protection for the feeding into units must be given. The system attenuation of the optical fibers, including the connectors, must not exceed 10 dB. System attenuation and attenuation of optical components must be determined. This can be achieved by measuring attenuation and reflection with an appropriate measuring instrument. For pigtails, a total value of < 0.4 dB (measured to a reference plug) can be assumed due to the dead zone of the reflectometer. These measurements must be made with a sufficient length of optical fiber, at the input and output of the device which has to be measured. Fiber-System Installation: Fiber-cable connectors have to be of the same type (E2000APC8°) as the connectors used for the unit. The fiber-optic cables are connected to the optical transceiver. Angled connectors are not compatible with straight optical connectors; non-compatibility of connectors will result in permanent damage to both connectors.
3 Commissioning Page 27Before connecting the fiber cables, follow the procedure below to ensure optimized performance. It is important for these procedures to be carried out with care: ¾ Remove fiber-optic protective caps. ¾ Do not bend the fiber-optic cable in a tight radius (< 4 cm) as this may cause cable damage and interrupt transmission. ¾ Using high-grade alcohol and lint-free cotton cleaning swabs, clean the end of the fiber-optic cable that will be inserted in the optical connectors on the donor interface box. Use a fiber end-face inspection tool to scan both, the class fiber and its surrounding area. ¾ Check for dirt on the cladding, chips/pits, dirt on the ferrule, and scratches. ¾ Connect the fiber-optic cables by inserting the cable end into the laser receptacle and aligning the key (on the cable end) with the keyed slot. ¾ Do not use any index-matching gels or fluids of any kind in these connectors. Gels are intended for laboratory use and attract dirt in the field. ) Note: Care should be taken when connecting and disconnecting fiber-optic cables - use the connector housing to plug or unplug a fiber. Scratches and dust significantly affect system performance and may permanently damage the connector. Always use protective caps on fiber-optic connectors not in use. Cleaning Procedure for Fiber-Optical Components: Any contamination in the fiber connection results in additional optical transmission loss which could cause whole system failure. It is thus recommended that every fiber connector be inspected and cleaned prior to mating. The goal is to eliminate any dust or contamination and to provide a clean environment for the fiber-optic connection. When you clean fiber components, always complete the following steps carefully: 1. Turn off the ION system (laser sources) before you inspect fiber connectors. Never look into a fiber while the system lasers are on! 2. Check the connectors or adapters with a fiberscope before cleaning. 3. If the connector is dirty, clean it with a lint-free wipe (dry cleaning). 4. Inspect the connector.
User’s Manual for ION™-M7P/85P/17P/19P (ML-Cab) Page 28 MF0143AUA.doc 5. If the connector is still dirty, repeat the dry cleaning technique. 6. Inspect the connector. 7. If the connector is still dirty, clean it with 99% isopropyl alcohol (wet cleaning) followed immediately with a dry clean in order to ensure no residue is left on the endface. 8. Repeat steps 5 through 7 until endface is clean. Note: For a more detailed description please refer to: http://www.cisco.com/en/US/tech/tk482/tk876/technologies_white_paper09186a0080254eba.shtml

EXTERNAL ALARM INPUTS AND OUTPUTS G1038Z0 G1038Z0 figure 4-1 Flange connector, 5 poles figure 4-2 Flange connector, 7 poles The alarm outputs (open collector output 5 V / 1 mA) are normally low. In case of an alarm they are high active (5 V). They can be used to monitor alarms with an external alarm indicator. The +28 V pin (for its location see figure 4-2 Flange connector, 7 poles) is protected by a 500 mA thermoswitch. In case of exceeding this current between pin 7 and GND and/or in case of a failure of the VSWR module, the thermoswitch turns into a high-resistive status. In this case no fuse needs to be replaced. Just wait a few minutes until the thermoswitch reaches the normal operating temperature again. ) Note: The manufacturer / supplier of this system accepts no liability for damage caused by equipment connected to external outputs or by effects from such equipment. As accessory equipment the alarm kit is available to connect external devices to the external alarm inputs and outputs. For the exact designation, please refer to chapter 6.3 Spare Parts.
