OLT-20 series Optical Loss Tester
OLT-20 Optical Loss Tester integrates
laser source module and power meter module in one set, which can
perform power testing and link loss testing in optic fiber network
conveniently. The typical applications include fiber identification,
attenuation and loss measurement, continuity verification and fiber
link transmission quality evaluation for installation, routine
inspection and daily maintenance of MAN, WAN and CATV systems as
well as for lab test and research work.
