Analog RFoF optical Transmitter is used to convert RF signals to optical signals that can be sent and carried over long distances of fiber optic cable.
The Optical Receiver converts them back to an RF signal. The two units are connected through 1 single mode fiber up to 40Km.
RF over Fiber modules (RFoF) are commonly used in L-band, S-band satellite, radio telescopes, RF antennas distribution, broadcasting audio, and video, timing synchronization and GPS applications and other telecommunications.
It's very easy and cost effective to extend a signal from any antenna, Modulator or RF instrument, point to point or multipoint to multipoint using fiber optic splitters.
Applications
IMPORTANT NOTE*** (it is very important to interface our unit with SC/APC - Angle Polished Connector to avoid any light reflections.
If your fiber is terminated with the SC, ST, FC /PC flat connector, you need to use an optical jumper from PC type to SC/APC for proper conversion.
