2-Channel Optical Attenuator And Optical Power Meter 100ms
Stabilization Time
U8752 dual channel optical attenuator and optical
power meter is a powerful test equipment, its characteristics are
mainly reflected in the following aspects:
First, the U8752 is able to set optical attenuation
and optical power output quickly and accurately. This feature
enables it to provide accurate and reliable data support in optical
network testing, equipment calibration, and performance evaluation
of optical communication systems.
Secondly, the optical power control stabilization time
is less than or equal to 100 milliseconds, ensuring the stability
and accuracy of the measurement results. This feature is
particularly important in applications that require fast response
and accurate measurement.
In addition, the dual-channel design enables the U8752
to measure the optical power and optical attenuation of both
channels at the same time, which greatly improves the test
efficiency. This design is a great convenience for optical network
testers who need to monitor multiple channels at the same time.
