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.

S-Band RF over fiber optic cable transport system. Can be customized for transport distances of up to 150 Km. Can also provide LNB power at various voltages.
4 LNB's satellite distribution system for MDU over 1 fiber - DWDM- High Power
4x Ch L-Band DWDM Transmitter for Satellite TV. Designed for delivery of satellite service to more than 5000 locations, or to be used as a satellite to home LTTH system. Used similarly as many CATV FTTH systems, instead LTTH units transport 4 independent satellite signals off the Dish and mux them into a single fiber. DWDM light spectrum could be amplified by EDFA, this is why we can distribute the
