OFW-2320TRX UHF Fiber Optic Interfacility Link (IFL) System

Description

Click for larger image

The OFW-2320TRX UHF Fiber Optic Interfacility Link (IFL) System is the principle hardware for long-haul transmission of UHF signals in the frequency range of 225 MHz to 400 MHz over singlemode fiber optic cable. The OFW-2320TRX is designed to provide full duplex signal transmission between a UHF Ground Station and its transmit/receive antenna complex with as much as 50 km of optical cabling. The OFW-2320TRX system architecture consists of a Remote Unit located at the antenna complex such that it is optically interconnected to a Local Unit at the ground station. The OFW-2320TRX is compatible with UHF SATCOM Transceivers and can replace the conventional RF Coax Cables that interconnect the transceivers to their respective antennas. The system’s optical conversion process is functionally independent of the RF carrier’s data modulation format. The links have low noise and high dynamic range characteristics, a wide operating temperature range and provide turnkey installation. The system provides status monitoring through the use of an onboard processor that communicates with a host computer over a RS-232 I/O interface.

A typical antenna installation configuration would resemble an architecture where the OFW-2320TRX remote unit is installed such that it is interconnected to the Antenna via an uplink/downlink duplexer. Specifically, the uplink optical channel connects to the Power Amplifier (PA), the downlink optical channel connects to the Low Noise Amplifier (LNA). Similarly, the ground station installation configuration would resemble an architecture where the OFW-2320TRX uplink and downlink optical channels are mated to the radio SATCOMM transceivers. With the addition of an optional WDM module will enable the system to have bi-directional uplink/downlink transmission over a single fiber optic cable.
