分组编码，16 B18 B，光纤8B 10 B分组编码方案目前用于以大约1Gb/s工作的几种光纤应用中。该代码导致比数据速率大25%的符号速率（即，25%的开销）。我们描述了一种替代的块编码方案，可用于实现低开销的光纤多Gb/s的链路编码。该编码方案实现起来极其简单，生成直流平衡信号，并为控制信令提供非数据码字。作为示例，描述了16 B18 B代码（开销12.5%）。
block coding, 16B18B, fibre optic An 8B10B block coding scheme is currently employed in several fibre optic applications operating at approximately 1Gb/s. This code results in a symbol rate that is 25% greater than the data rate (i.e. 25% overhead). We describe an alternative block coding scheme which may be used to implement lower overhead coding for fiber optic multi-Gb/s links. The coding scheme is extremely simple to implement, generates a d.c. balanced signal and provides non-data codewords for control signaling. As an example, a 16B18B code (overhead 12.5%) is described.
