DIN EN 61280-2-11-2006 光线通信子系统试验程序.第2-11部分:数字体系.光信号质量监控用采用振幅柱状图评定的平均Q因子的测定(IEC 61280-2-11:2006)
Fibre optic communication subsystem test procedures - Part 2-11: Digital systems - Averaged Q-factor determination using amplitude histogram evaluation for optical signal quality monitoring (IEC 61280-2-11:2006); German version EN 61280-2-11:2006
The purpose of this part of IEC 61280 is to define the averaged Q-factor and to provide a procedure to measure it by using amplitude histogram parameters such as the standard deviation and average level.The averaged Q-factor and amplitude histogram are useful for monitoring changes in optical signal quality in installed optical networks.
