摘要
色散和自相位效应是制约1550 nm有线电视(CATV)系统无中继传输距离的主要因素。针对传统补偿方法在模拟CATV系统应用上的缺点,提出了双波长波出复用(WDM)技术,通过合理的频道划分,实现对色散和自相位的有效补偿。
The fiber dispersion and fiber self-phase modulation （SPM） are main reasons limiting the transmission distance of 1550nm CATV system. In view of the weakness of traditional compensation methods using in CATV system, this paper gives a dual - wavelength WDM scheme. This scheme can efficiently compensate fiber dispersion and SPM effect by reasonable frequency division.
