D Yedemc Fiber Optical Multi-Meter Cable Tester

This D Yedemc fiber optic cable tester can measure 8 standard wavelengths: 850 / 980 / 1300 / 1310 / 1490 / 1550 / 1625 / 1650nm, with a test range of -70dBm+6dBm and a 1mw red light source. This hand-held optical power meter is primarily used for measuring uninterrupted optical signal power, optical fiber link loss testing, and optical fiber line on-off testing. It is powered by a single chip microprocessor that performs all the necessary functions. Optical cable construction and maintenance, optical fiber communication, optical cable sensing, optical CATV and other fields make extensive use of this technology.
