The OFW-3427 L-Band Fiber Optic IFL System is the principle hardware for long-haul transmission of RF signals in the frequency range of 800 MHz to 2250 MHz over singlemode fiber optic cable. The standard transmitter and receiver configuration provides 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 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. The I/O parameters include laser bias current, optical receive power, internal temperature and alarm monitoring. In addition, an optional integrated Bias-T for LNB powering may be specified. The OFW-3427 provides a high-performance, cost-effective solution for transporting L-Band signals over single mode fiber.
