Intermediate Frequency Fiber Optic Subsystem
The OFW-400 Intermediate Frequency (IF) Fiber Optic Interfacility Link (IFL) System is the principle hardware for long-haul transmission of IF signals in the frequency range of 2 MHz to 512 MHz over singlemode fiber optic cable. The standard system configuration supports transmission distances up to 50 km. An optional extended-range configuration can be specified that increases the link range to 80 km. The system’s optical conversion process is transparent to the IF carrier’s data rate and modulation format, which supports Analog and next generation Software Defined Radios.
The core Fiber Optic Transmitters (FO TX) and Fiber Optic Receivers (FO RX) contained within the OFW-400 also have integrated User adjustable RF attenuators which allow for up to 30 dB of RF level adjustment. The use of these attenuators can be used to trade off between system sensitivity and maximum system gain.
The OFW-400 provides status monitoring through the use of an onboard processor that communicates with a host computer over a Serial and/or a Ethernet interface. The I/O parameters included laser bias current, optical receive power, internal temperature and alarm monitoring. In addition, an optional Low Noise amplifier (LNA) or integrated Bias-T for remote LNA power-ing may be specified.
