SK-OR-860F3 FTTB CATV Receiver
Features
Overview
SK-OR-860F3 FTTB Optical receiver is specially designed to meet the market’s needs. This equipment adopts GaAs MMIC amplifier component reasonably combined with NEC GaAs amplifier module, optimized circuit design and keep the output level stable while input optical power is between -7～+2dbm. It is featured with high performance index; Output adjustable attenuation and equalization makes the debugging of CATV network project very conveniently. It’s first recommended equipment to build HFC network system.
