摘要
This Recommendation specifies multichannel optical line system interfaces for the purpose of providing future transverse compatibility among such systems.
This Recommendation defines interface parameters for systems of four, eight and sixteen channels operating at bit rates of up to STM-16 on fibres, as described in Recommendations G.652, G.653 and G.655 with nominal span lengths of 80 km, 120 km and 160 km and target distances between regenerators of up to 640 km. A frequency grid anchored at 193.1 THz with interchannel spacings at integer multiples of 50 GHz and 100 GHz is specified as the basis for selecting channel central frequencies.
本建议规定了多线路光线路系统接口，目的是提供在这个系统上的未来横向兼容性。本建议定义了运行在比特率高达STM-16 光纤上的4，8和16线路系统的接口参数，就象建议 G.652, G.653 和 G.655描述的那样，再生器之间的目标距离高达640 km，名义跨度 80 km, 120 km 和 160 km。一个铆定在193.1 THz，通道间的空间以 50 GHz 和 100 GHz 整数倍增长的频率栅格被作为选择信道中央频率的基础。
