Four-Channel Multimode Optically Controlled Optical Attenuators Can
Be Cascaded
The four-channel multi-mode optical attenuator integrates four
independent optical attenuator channels into one, each channel can
accurately control the optical signal strength. This design not
only greatly saves equipment space, but also significantly improves
test data throughput and test rate, meeting the test requirements
of complex optical fiber communication systems. At the same time,
it supports multi-mode fiber and is suitable for a variety of fiber
types, such as 62.5/125um and 50/125um, with higher flexibility and
applicability.
