The OP831 is designed to perform bidirectional insertion loss measurements on single-fiber OR multi-fiber optic cables with optical switches. The integrated source and power meter together with the OPL-PRO application software allow for a fully automated bi-directional insertion loss analysis of the connected cable. This rack-mounted instrument can be equipped with either single wavelength or dual wavelength LASER or LED sources.

Product Features
