Televes FiberKom Optical Mini Receiver

Further details of Televes FiberKom Optical Mini Receiver

The Televes FiberKom optical mini receiver is designed for small MDU (Multi Dwelling Unit) systems. It receives one optical signal in the 1200-1600 nm wavelength range and restores it with amplification on one RF output covering 47-1220 MHz. It can be used in RF Overlay, FTTB and FTTH applications.
