摘要
DWDM技术的广泛应用,对维护人员提出了更高的要求,光缆割接的相关要求也更加严格。在每次光缆割接完成后,光缆的衰耗值、距离都发生了变化,造成某些或全部波道发生误码而不能正常恢复。武汉站北电设备高速环网维护过程中多次出现过类似问题,经过反复的研究和分析,发现是因为色散原因造成的,因此在割接之前需要重新考虑调整色散补偿值。为了更好地完成光缆割接工作,文中通过历次光缆割接积累的经验,总结出一套完整的用于光缆割接中调整高速环网的色散补偿值的方法,作为未来光缆割接提供帮助和参考。
The wide application of DWDM technology posed higher optical line cutting. The attenuation and length of the optical line change requirement for the service personnel with each cutting of the line, causing error codes in many, if not all, optical channels. Analysis shows that the reason is dispersion. Therefore, the dispersion compensation should be readjusted after each cut of the optical line. Based on practical experience and the analysis, this paper proposes an overall solution to the dispersion compensation adjustment in the optical line cutting, which is a help and reference for optical line cutting practice.
