FIS Blue’s Ruggedized SMPTE Hybrid Fiber Optic Cable Tester is designed for harsh work conditions where handheld units are not appropriate. The SMPTE Test Set utilizes a passive remote loopback unit for single ended testing of both optical fibers as well as power for the built-in copper conductor tests. The set checks all 4 copper conductors for continuity, polarity and shorts as well as verifying the integrity of the grounding shield in the cable with simple pass/fail visual indicators. The main control unit houses the optical fiber power meter readout, copper conductor test indicators, and the SMPTE fixed plug connector. The Remote Unit contains the SMPTE fixed socket connector. The FIS Blue SMPTE Tester 304M is proudly Made in the USA to the highest quality standards and comes with a 1-year warranty.
