Aerospace series - Elements of electrical and optical connection - Test methods - Part 603: Optical elements - Change of power distribution
航空航天系列 - 电气和光学连接元件 - 测试方法 - 第603部分:光学元件 - 配电变化
This standard specifies a method of detecting changes in the power distribution when using optical connection elements (including permanent connections) with optical contacts and fibre optic couplers.
These changes are attributable to mode-selective loss mechanisms or uneven distribution of coupled modes.
It shall be used together with EN 2591-100.
