Optically Controlled Optical Attenuator 100 Ms Optical Power
Control Stabilization Time
The function of U8734 optical attenuator is mainly reflected
in the accurate control and attenuation of optical power.
Specifically, it is mainly used in the index measurement of optical
fiber communication system, signal attenuation and system test of
short-distance communication system. The optical attenuator can
perform the predicted attenuation of the optical signal according
to the predetermined requirements, which is very critical when
adjusting the optical signal output power transmitted by the
optical fiber communication system or the detection system, helping
the system to achieve the best operating state.
In addition, the U8734 optical attenuator can realize
parallel data measurement in the multi-channel error measurement of
optical transceiver module, provide parallel, fast and accurate
optical power input, and greatly improve the test efficiency. It
can also play an important role in the sensitivity measurement of
optical receiving modules. At the same time, it can also be used in
optical communication network integration testing to help test
network transmission performance and network management functions.
