Optical Power Meter (OPM)

Cat No: OPM510/OPM520

Tempo Communications Optical Power Meters (OPM510/520) are available in standard and high-power versions for the Telco and MSO markets. Absolute and referenced power measurements ensure fast and accurate loss budget and insertion loss measurements. When placing tones on the fiber using a Tempo Communications source, the optical power meter will definitively identify fiber optic cables.

The rugged, IP54-compliant package provides confidence when testing singlemode and multimode networks. See Models tab for options and available OPM Adapters.
