求翻译：用尾纤对光口进行硬件环回测试时应加衰耗器，以防接收光功率太强导致接收光模块饱和，损坏接收光模块是什么意思？

The hardware loopback test using a pigtail optical port should be added attenuation, in case the received optical power is too strong to lead to saturation of the receiver optical module damage to the receiver optical module

The pigtails for optical port hardware loopback tests should be when the loss is to prevent receiving optical power is too strong causing the receiving saturated, damage the module received optical module

Carries on with the tail filament to the light mouth the hardware link returns to when the test should add the attenuation network, guards against the receive luminous power too to cause the receive light module to be saturated, damage receive light module

Fiber optical hardware Loopback tests should be carried out and attenuation to prevent receiving optical power is too strong saturated received light module, damaged receiving optical module
