Optical Passive Device including: optical fiber, connector, filter, CWDM/DWDM module, coupler, splitter, isolator, optical switch, circulator, attenuator
There are various types of optical passive devices, and the main test specifications are IL and RL, as shown in the following block diagram:
Insertion Loss(IL) test
Return Loss(RL) test
Dimension single fiber IRL meter uses a high stability laser source and a high precision optical power meter for mandrel-free return loss testing and high-speed insertion loss testing. The single-wavelength loss test time is less than 0.5s, and the minimum return loss detection can be achieved -75dB. Includes 6 testing wavelengths for single mode and multiple mode
(multiple mode :850nm, 1300nm, single mode :1310nm, 1490nm, 1550nm, 1625nm). RLM fast and accurate measurement function make it an ideal tool for improving production efficiency and quality control.
Single fiber IRL Meter
Multifiber IRL Meter
PDL test --light source、Polarization controller、OPM(polarization insensitive)
Other parameters: Isolation, Uniformity, Directivity test is similar to IL/RL.
For the field of manufacturing test, the test instrument requires the characteristics of fast test speed, high precision, good stability and convenient expansion. The module + platform design test solution has great advantages in instrument expansion, data/report saving, programmability and so on.
