Overview
Communication Components, Inc. GPS Over Fiber (GPSoF) Systems provides an innovative and cost effective means of routing the GPS signal over a fiberoptic network to a remote Base Station location. This system is ideal for CRAN (Centralized Radio Access Network) deployments and In-building DAS installations when the Base Radio is in a remote location with no direct availability of GPS signal. Technical Description: The Generation Two (Current Gen) GPS-FO-Tx-1A GPS to Fiberoptic Transmitters upconvert the GPS RF signal from any active GPS antenna to the optical band to enable transmission up to 8 km over single fiberoptic lines (max distance for hybrid cable is 4 km, limited by power line). GPS Antenna bias current is provided and comprehensive alarm detection and reporting of the GPS antenna and the fiberoptic transmitter are delivered over the single fiber to the companion Fiberoptic to GPS Receiver for local monitoring. The Transmitter can be powered via a hybrid fiberoptic cable or from any -48VDC source. An optional outdoor AC to -48VDC power supply is also available. The transmitter utilizes ultra-linear, high dynamic range DFB laser technology. Automatic Power Control is also used to stabilize the optical power. |
