Loss measurement of optical passive components
The AQ2300 supports measurement of optical loss measurements for passive components such as optical fibers, connectors, couplers, etc. By combining optical sources, power meters, attenuators and switching modules in single modular system, engineers can evaluate the optical insertion loss and crosstalk of various optical passive components.
[Measurement items] Optical insertion loss, crosstalk
MPO component inspection system
The AQ2300 DFB Light Source, combined with an AQ2300 Series optical power meter, enables accurate insertion loss measurements of MPO connectors and other multi-fiber optical components. Optical switches can also be used to efficiently test multiple fiber channels.
For more detailed analysis, the AQ7420 or AQ7421 High-Resolution Reflectometer can complement these loss measurements by identifying the location and magnitude of individual reflections. This helps detect localized defects, such as micro-cracks, that may be difficult to identify through conventional insertion loss measurements alone. By combining optical loss measurements with high-resolution reflection analysis, users can perform a more comprehensive evaluation of MPO and multi-fiber optical components.
[Measurement items] Insertion loss, total optical return loss, partial optical return loss, micro-crack detection
