A data transmission method, and apparatus and system therefor

By setting a specific number of pilot symbols, training symbols, and frame synchronization symbols in the data frame, the problem that existing framing schemes cannot adapt to multi-wavelength or multi-subcarrier transmission is solved, achieving higher-speed, robust, and reliable data transmission and hardware compatibility.

Abstract

本申请实施例公开了一种数据传输方法、及其装置和系统，可以兼容现有400ZR+、800ZR、800ZR+的DSP成帧方案，更有利于硬件实现，还可以适用未来采用多波或多子载波传输的场景，例如，采用QPSK调制的800Gbps多子载波传输、采用16QAM调制的1.2Tbps多子载波传输、采用16QAM调制的1.6Tbps多子载波传输，甚至更高速率如2.4T / 3.2T等传输场景。该方法包括：发送W个数据帧，其中，在一个偏振方向上，任意一个数据帧包括的符号数目为87552，每个数据帧包括12个子帧，每个子帧的包括的符号数目为7296，其中，W为偶数。
