标准摘要
[中文适用范围]： 该测试程序的目的是测量光纤数字子系统在指定条件下的比特率容限。比特率容差是由满足指定误码率的光纤数字子系统的时钟频率范围定义的。 [外文原描述]： Enables the measure of the bit-rate tolerance of the fibre optic digital subsystem under specified conditions. Bit-rate tolerance is defined by the clock frequency range of the fibre optic digital subsystem which meets the specified bit error ratio.
英文名称Fibre optic communication subsystem basic test procedures - Part 2-4: Test procedures for digital systems - Bit-rate tolerance measurement
