ITU-T G.709.3/Y.1331.3 (12/2020)

灵活的OTN长距接口
ITU-T G.709.3/Y.1331.3建议书定义了灵活的、称作FlexO的光传输网(OTN)的长距离接口,该接口支持多个此类接口的绑定(即分组),从而使一个或多个客户端信号(如一个或多个OTUCn(n ≥ 1))能够在一个或多个物理接口上通过一个或多个光支路信号(OTSi)传输。本建议书规定了FlexO长距离接口的帧结构,该接口使用前向纠错码,具有比ITU-T G.709.1/Y.1331.1规定的FlexO短距离接口使用的更高的编码增益,并且将OTUCn客户端信号多路复用到一个FlexO组的有效载荷中。
第2版包含对1.1版的以下扩展: – 增加带有OFEC的100G、200G和400G FlexO(16,附件D、E、G,附录III、IV、V,参考资料) – 添加带有级联前向纠错(FEC)的100G FlexO(15.4.1,15.5.4)
– 添加将OTUCn客户端信号多路复用到一个FlexO组的有效载荷中(附件F)。
本建议书包括附录IV中规定的工作表的电子附件。
