FTTH Fiber Optic CATV Receiver Node Product
Description
The RDH2090R FTTH 2 Ways output CATV AGC receiver with work bandwidth 45~1002MHz, AGC function, output level Vo=90dBµV±1dB (Pin=-7~+1dBm), applies to FTTH system, it is a low power consume, high performance ONU for RFTV broadcast network. RDH2090R adopt high sensitivity optical receiving tube and Ruidian specialized low noise match circuit, 3.5%modulate full channel transmit power receiving and the CNR can reach high index 46dB. RDH2090R has three types according to different functions. RDH2090R is standard type, RDH2090F is build-in filter, RDH2090D is build-in WDM widely used in PON systems. Customer could choose the suitable model according to their systems application.
