產品簡介

OFW-2320TRX 級—3 GHz 雙向RF模擬光纖收發模塊

詳細介紹

The OFW-2320TRX RF Fiber Optic Transceiver is the principle hardware for long-haul transmission of RF signals in the frequency range of 100 MHz to 2500 MHz over singlemode fiber optic cable. The OFW-2320TRX is designed to provide full duplex signal transmission between an antenna head-end and radio base station complex interconnected with as much as 50 km of optical cabling. The OFW-2320TRX is compatible with various radio transceivers and can replace the conventional RF Coax Cables that interconnect the transceivers to their respective antennas. The system function is 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 or RS-485 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 base station installation configuration would resemble an architecture where the OFW-2320TRX uplink and downlink optical channels are mated to the radio 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.
