摘要
有线数字电视信号在长距离光纤传输中存在色散问题,色散使系统的CSO指标劣化,适当地进行色散补偿可以大幅提升CSO指标,降低误码率(BER)。
Dispersion often exists in the cable DTV signal transmission in long-distance fiber-optical, which makes the CSO index of system degraded. Properly compensating for the dispersion can improve CSO index significantly and reduce the Bit Error Ratio(BER).
