Abstract

本申请公开了数据传输、编码方法、解码方法、装置、设备及存储介质。数据传输方法包括：第一芯片接收第二芯片器件发送的第一数据流；第一数据流为采用第一前向纠错FEC码型编码的数据流；第一芯片器件对第一数据流再进行至少一次编码，得到第二数据流；其中，第二数据流为至少采用第一FEC码型和第二FEC码型编码的级联FEC码流。数据编码方法包括：第一电路接收第二电路通过以太网接口传输的第一数据流，第一数据流是采用RS码对原始数据进行编码得到的；第一电路对第一数据流进行BCH编码，得到第二数据流。本申请提供了级联编码的方式，使得增益更高，简化FEC码型的转换过程，减少FEC码型转换时所要耗费的时延及设备功耗，提高数据可被传输的距离和速度。
