摘　　要：针对G.654.E光纤即将商用于超100 Gbit/s OTN系统而无相应规范标准的问题,本文首先利用香农定理和光信噪比公式理论分析传输速率的受制因素,接着分析OTN系统的最大光放段损耗值中的中继段损耗、活接头损耗和色散补偿光纤插损,然后推算出G.654.E光纤承载超100 Gbit/s OTN系统中不同传输速率下的复用段距离,并与实际测试值进行对比分析,最后结合骨干网络现状情况,提出G.654.E光纤承载超100 Gbit/s OTN技术应用建议。Aiming at the problem that G.654.E optical fi ber will be used in over 100 Gbit/s OTN system without corresponding standard,firstly the restricted factors of transmission rate are analyzed by Shannon's theorem and the formula of OSNR,then the relay loss,live joint loss and dispersion compensation fi ber insertion loss in the maximum optical amplifi er loss value of OTN system are analyzed,then the multiplexing distance of G.654.E optical fiber over 100 Gbit/s OTN system at different transmission rates is calculated,and compared with the actual test value,fi nally combined with the current situation of backbone network,the application suggestion of G.654.E optical fi ber over 100 Gbit/s OTN technology is put forward.
