The manual is organized into the following chapters:

1.1 Theory of Operation The USU RF to Fiber Modules provides a single-band link from a Headend distribution center to multiple local antennae. RF signals are distributed over a pair of single mode fiber optic distribution lines to each USU Remote. Each Headend module can interface to multiple remote modules, the number depending upon the Headend model. The Headend modules do not transmit directly out into the air. Note! The remote module fiber optic I/O's are band specific, but the Headend fiber optic I/O's are not;

The LNKFIB-H04 is identical, but with one bank of four removed. Each of the groups of four consists of a single RF Input feeding a single Laser Transmitter split optically to four fiber optic outputs. The four matching fiber optic Inputs each go to their own photodiode receiver, followed by a 0 to -15dB digitally controlled attenuator providing uplink gain control. The RF signals from the four digital attenuators are combined into a single RF output. The group of four RF input and output combining inside the module alleviates the need for external combining / splitting.

Figure 11 Remote Module (Rear View) DCM000000104 Rev Q 3-3 Headend to Remote Interconnections 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. 3-4 DCM000000104 Rev Q Chapter 4 Remote Module 4 Introduction This chapter contains specifications and information for the LinkNet Uniserv Unit RF-FIBER Remote Modules. 4.1 Power for the Remote Module The US remote module may be powered by any source of negative ground +28VDC power capable of delivering 1 Ampere. This includes the optional single US remote module US-PS01 power supply. 4.2 Battery Backup of Remote Module If the US remote module is being used without a battery it must be configured to NOT use a battery. Without a battery the USU will shut down or reset with any disruption to the AC power. When power is re-established the system will restart automatically. External batteries may be connected using the CAB000000055 Battery Cable. The USU has a built-in battery charger that will automatically recharge the attached battery.

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.

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:

DLGATTN ###:

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. 5-2 DCM000000104 Rev Q Chapter 6 Antenna Installation 6 Introduction This chapter contains antenna installation and warning information for the LinkNet Uniserv Unit RF-FIBER Interface Modules. 6.1 Antenna Installation All Antenna installation to be performed by qualified technical personnel only.
