OFW-5800 GPS/Shipboard Fiber Optic Antenna Link

Description

Click for larger image

The OFW-5800L Fiber Optic Antenna Link (FOAL) consists of an antenna module, located on the topside mast structure, and a receiver module, located in the below deck navigation space (IC/GYRO Room). OFW-5800L Fiber Optic Antenna Link (FOAL) is configured to receive L1 and L2 GPS RF signals, generate a RF intensity modulated optical carrier and transmit the optical carrier to the receiver module via a shipboard fiber optic cable. OFW-5800L Fiber Optic Antenna Link (FOAL) detects and converts the optical carrier to the GPS RF signals and distributes the GPS signals to the GVRC. When configured as a Dual FOAL Subsystem, the OFW-5800L Fiber Optic Antenna Link (FOAL) consists of two independent FOALs each interconnected through a corresponding NAVSSI/GVRC RTS. In this configuration the OFW-5800L Fiber Optic Antenna link (FOAL) is capable of meeting the antenna subsystem requirements of the NAVSSI/GVRC DUAL RTS architecture.
