浅谈DWDM误码处理方法

通信传输网络在大幅度上涨的业务量形势下变得日趋复杂。原有的光纤单波传输和时分复用方式,无法适应业务量上涨的需求。DWDM系统用于骨干传输网络,提高了传输容量。由于DWDM系统下的SDH环在收发端进行了波长转换及复用解复用,中间传输的光中继站点较多,信号流较直接光纤相连接的SDH环复杂,特别是在处理跨局站点误码的时候,需要排查的站点较多。因此,本文提出DWDM系统误码处理的方法,并以铁路总公司现网的骨干网西南环为例,对DWDM的误码处理方法进行了探讨。

Communication transmission network in sharply rising business situation become increasingly complex.The original fiber single-wave transmission and time-division multiplexing method,cannot meet the requirement of business.DWDM systems used in backbone transmission network,improve the transmission capacity.Made a start in the closed because of the DWDM system of SDH ring under the wavelength conversion and reuse solutions for reuse,intermediate transmission light relay points more,signal flow is directly connected fiber SDH ring complex,especially in dealing with across the board site error,need more stops.Therefore,the paper proposed a method of DWDM system error processing,and the railway corporation now network as an example,the backbone of southwest of DWDM error processing method are discussed in this paper.
