RFoG Optical receiver
PTR3252
PTR3252 RFoG is a compact optical receiver, it applies to based on the Docsis technology FTTB and FTTH bidirectional HFC transmission network (RFoG applications). Forward with optical AGC function, can keep the output level of the output unchanged, with the forward RF output of the two allocation formula; former level of the model using low-noise MMIC amplifier, post-GaAs modules with high output level and low distortion characteristics; burst reverse optical transmitter and effective use of the upstream optical network may correspond to a return receiver receiving multiple return optical transmitter, reducing the number of front-end uplink receiver, while significantly convergence to reduce the uplink noise, and has a secondary low-pass filtering, to effectively suppress noise, the power part using military grade device design, highly reliable lightning effects.
