Headend to Remote Interconnections 3-4 DCM000000104 Rev Q 3.2 Headend to Remote Interconnects The single mode fiber optic interconnections between the Headend and Remote modules are to be made in whatever manner suits the system configuration. For the CAN Network connections please refer to DCM000000103. 3.3 Fiber Optic Connections • All Fiber Optic Cabling must use 9/125 or similar Single-Mode (yellow jacketed) high-quality cable. This cable should typically have less than 0.5 dBo (optical dB) insertion loss per kilometer. • The cable manufacturer's minimum bend radius must be observed. • Most Powerwave products use SC/APC connectors. Note that the "APC" is critical. These are angle-polished connectors and are required to reduce reflections. • Fiber-Optic Patchcords should be avoided; Fusion-Splices are preferred to reduce reflections. • Fiber-Optic Connectors, both on cables and equipment, should always have their dust caps in place when not in use. The connector tips must be kept clean and scratch free, and should always be cleaned properly before being connected. • Optical Reflections back into laser diodes cause a disturbance in the lasers gain cavity creating noise and distortion. An OTDR or other fiber optic instruments should be used to check optical reflections. Fiber optic return loss should be less than -50 dBo. • There is a 2 to 1 Relationship between optical loss and RF loss. One dBo (optical dB) of optical loss corresponds to 2 dB of RF loss.

Remote Module Per-Carrier Derating DCM000000104 Rev Q 4-3 4.4 Remote Module Per-Carrier Derating All signals that fall within a given Pass-Band range will “share” power amongst them. A multiple channel effect is intermodulation, signals produced from non-linear effects between the intended channel signals. This intermodulation may cause interference to receiving equipment. In order to minimize intermodulation signals, power de-rating must be applied. In the USA there are FCC Intermodulation Specifications published in the EIA Standard PN2009. Further derating is also required to maintain the integrity of complex digital communications signals. The table below gives the maximum per channel output levels allowed as a function of the number of channels. Note that depending on the actual input levels, the gain may need to be reduced to comply with the above regulations. The figures shown are to the nearest dB.

DCM000000104 Rev Q 5-1 Chapter 5 Operation 5 Introduction This chapter contains operational and standard safety information for the LinkNet Uniserv Unit RF-FIBER Interface Modules. 5.1 Operation Normal operation for both USU Headend and Remote modules: • POWER / OPERATING - GREEN when the module is operating. • FAULT – Red if the internal diagnostics detect a problem. • LASERS ON - GREEN when any one of the lasers are operating. 5.1.1 Fault Indications Each module continuously performs internal diagnostics. If a problem is detected it will activate its Red Fault LED and Fault Relay. Faults detected include; • Over Temperature. • Misc. Internal Faults. Detailed faults are detected by the optional Gateway Module. Details may also be determined via an RS232 connected Terminal Emulator using the LIST command. 5.1.2 Configuration and PC Commands It is possible to re-configure modules in the field, either with a personal computer (PC) or via the optional LinkNet Gateway Module. To use a PC it is necessary to connect the DB9 RS-232/USB connector on the module to a standard DB9 RS232/USB connector on the PC. On the PC a terminal emulation program such as HyperTerminal is used to communicate to the LinkNet module. The settings are 9600 baud, 8 bits, no parity, and 1 stop bit. Commands are one or two words followed by pressing Return. Commands may be given in upper or lower-case. Available commands are listed below for each module. Headend Modules: ACCESS USER: Required as a simple password to gain access to customer settable parameters and diagnostics; This times-out after 10 minutes, and may have to be retyped. HELP or ?: Displays a list of Available Commands. LIST: Displays Current Settings and Status Faults, Etc. VER: Display the current Version of Software. ENABLE 1 or 0: Enables or Disables the Module. DIGATTN x yyy: Displays or Sets the Uplink Gain Reduction yyy, which is in tenths of a dB. The Optical to RF Path being set is x, which is; x = 0 is for Uplink Optical to RF Path A1 x = 1 is for Uplink Optical to RF Path A2 x = 2 is for Uplink Optical to RF Path A3 x = 3 is for Uplink Optical to RF Path A4 x = 4 is for Uplink Optical to RF Path B1 x = 5 is for Uplink Optical to RF Path B2 x = 6 is for Uplink Optical to RF Path B3 x = 7 is for Uplink Optical to RF Path B4
Configuration and PC Commands 5-2 DCM000000104 Rev Q Remote Modules: ACCESS USER: Required as a simple password to gain access to customer settable parameters and diagnostics; This will time-out after 10 minutes, and may have to be re-typed. HELP or ?: Displays a list of Available Commands. LIST: Displays Current Settings and Status Faults, Etc. VER: Display the current Version of Software. ENABLE 1 or 0: Enables or Disables the Module. DLGATTN ###: Displays or Sets the Downlink Gain Reduction, which is in tenths of a dB. Please consult Powerwave Technologies Inc. for further support. 5.2 Gain Adjustments Gain adjustment is necessary to compensate for the variations in the fiber optic components of the Headend and Remote modules. This must be done after modules are deployed in a system, and anytime a module is replaced. The adjustments are on an individual RF path basis, and each path is adjustable downwards in 1dB steps up to -15dB. It is recommended that these adjustments be performed with the aid of a Signal Generator and Spectrum Analyzer. Uplink Gain: The uplink gain is adjusted at the Headend module on an individual RF path basis. Please refer to the Headend DIGATTN commands in the Configuration and PC Commands section. All DIGATTN values are set to 0 (Maximum RF Gain). While monitoring the RF gain via measurements, the individual gain paths are adjusted downwards with the DIGATTN command to meet the specified gain. This will optimize/balance both gain and noise. Downlink Gain: The downlink gain is adjusted at the remote module an individual RF path basis. Please refer to the remote DLGATTN commands in the Configuration and PC Commands section. All DIGATTN values are set to 0 (Maximum RF Gain). While monitoring the RF gain via measurements, the individual gain paths are adjusted downwards with the DLGATTN command to meet the specified gain. This will optimize/balance both gain and noise. 5.3 Signal Level Adjustments Signal level adjustment is necessary to ensure that the downlink RF carriers transmitted via the remote modules are not generating undesired intermodulation products, nor are they being distorted beyond use. Refer to the earlier section on Remote Module Per-Carrier Derating. It is recommended that these adjustments be performed with the aid of a Signal Generator and Spectrum Analyzer, and that they be done AFTER the gain adjustments. Adjust the downlink interface amplifiers and/or attenuators between the base stations and the Headend modules (see the Typical Application drawing) to achieve the specified derated per-carrier level. Uplink signals should be monitored as they feed into the base station, this is usually a site specific requirement.
