Products Description

ERB802A is the high end 2 output CATV network optical receiver. This type adopt GaAs MMIC amplification in preceding stage, post processing adopt GaAs power double module, built-in AGC design and reserve optical communication interface which can configure standard Class 2 network management responder. This is the main model in large CATV networks.
