摘　　要：作为有线电视网络的核心传输设备,直接调制光发射机的射频调制电平影响到激光器输出光波的非线性失真,光接收机的射频输出的调试影响到HFC双向网络的回传通道的性能,探讨光发射机和光接收机的调试原理和具体应用,以提高网络的传输性能。Direct modulate Light-transmitter is the core device in CATV network. Its RF modulate level has great effect on nonlinear distortion of the LASER export light wave. And the RF - OUT＇ Debug of Light-Receiver affects the performance of the answer channel of HFC Bidirectional Network. This article contains discussion about the debug principle and concrete application of Light-transmitter and Light-Receiver, which will improve the transmission performance of cable TV network.
