HY-21-R03 optical receiver is an outdoor 4 outputs waterproofing receiver. It is mainly used in the building, community or village with concentrated users and high level multi outputs distribution network. Also suitable to be used in the place where it is not convenient to take the electricity and single equipment drives many users. It can work together with ONU or EOC to realize the network convergence. 

HY-21-R03 optical receiver adopts MMIC as the pre-stage amplification and hybrid module in the backward stage. Adjustable attenuation and equilibrium makes the debugging extremely convenient. The users also can choose the module combination according to their actual requirements. Optimized circuit design guarantees the perfect performance and is the ideal model for CATV network.
