The OptoTest OP930-SM Insertion /Return Loss Meter measures IL and RL on fiber optical components fast and accurately. The return loss is measured with the "no mandrel" method, meaning neither matching gel nor mandrel wraps are required at the far end of the cable. The insertion loss is measured by utilizing the stable laser source of the return-loss in combination with the precision optical power meter. Features. Insertion Loss (IL) and Return Loss (RL) measurement on single mode fibers & cables. Fully automated, concurrent dual wavelength IL and RL. Displays both readings, IL and RL, at the same time. Mandrel free RL measurement, IEC/TIA approved RECM method. Approved to qualify all singlemode cables. USB Interface to custom applications or OPL_Pro, the comprehensive cable testing system. Various detector options, with interfaces to multifiber and multi-ferrule connectors. Specifications. Optical Power Meter; Measurement Range: +10 dBm to -80 dBm.
