GPS/Inmarsat Fiber Optic Antenna Link
The OFW-3478 GPS/Inmarsat Photonic Antenna Link is designed to perform E/O and O/E conversion of RF satellite downlink signals over a range of 1.0 GHz to 2.0 GHz. Specifically, the link can accept simultaneous RF inputs from both a GPS antenna and an Inmarsat antenna. The RF/optical signals can then be transported between the antenna head-end and the radio-processing center over an optical fiber cable up to distances of 50 km. An optional long-haul DFB laser 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. In addition, an optional integrated Bias-T for GPS and Inmarsat LNA powering may be specified. The system can be tailored for a variety of custom L-Band SATCOM applications.
The OFW-3478 system provides end-to-end status monitoring of it’s head-end and radio processing center units through the use of an imbedded software controlled onboard processor that can communicate with a M & C host computer over a RS-232 I/O interface. The I/O parameters include GPS and Inmarsat LNA current, GPS and Inmarsat laser bias current, GPS and Inmarsat optical receive power, internal temperature and alarm monitoring. The OFW-3478 provides a high-performance, cost-effective solution for transporting L-Band signals over single mode fiber.
