Optically Controlled Optical Attenuators Enable Parallel Data
Measurement
Application of U8744 attenuator:
Active optical module/Optical Device Test:
In the multi-channel error measurement of optical transceiver
module, parallel data measurement is realized.
In the sensitivity measurement of optical receiving module, it
provides parallel, fast and accurate optical power input;
200ms optical power control stability time, greatly improve the
test efficiency.
Optical communication network integration test:
Test network transmission performance and network management
functions in optical communication network integration.
Peculiarity
1.The optical attenuation and optical power output can be quickly
and accurately set. The optical power control stability time is
less than 200 ms.
2. Multi-channel attenuator is set at the same time, and multiple
ports are measured at the same time, saving a lot of measurement
time.
3. Built-in high-precision optical power meter ensures the
stability and accuracy of power monitoring.
4. Small size, compact structure, simple operation, intuitive
graphical user interface, multi-channel data preview, test status
at a glance.
