Describe Product

This product is FTTH (Fiber to the Home) optical receiver, with low power optical receiving and optical control AGC technique, which can satisfy the demand of FTTH, and also can match with ONU or EOC for realizing the integration of three networks. With WDM, 1550nm CATV to be photoelectric converted for RF output, 1490/1310 nm PON signals directly pass, can transfer CATV+EPON by only one pc FTTH.

The product is compact, easy installation, and an ideal product for FTTH CATV network.
