OFW Optical Power Meter

OFW handheld optical power meter for accurate measurement of optical signal power in ISP fiber optic networks. Wide measurement range of -70 to +6 dBm covers everything from long-haul backbone testing to FTTH subscriber verification. Supports 7 calibrated wavelengths: 850nm, 980nm, 1300nm, 1310nm, 1490nm, 1550nm, and 1625nm — covering all common single-mode and multi-mode fiber applications including GPON downstream (1490nm), upstream (1310nm), and OTDR testing (1625nm). Features a large backlit LCD display for clear readings in field conditions including dark splice closures and manholes. SC/FC universal adapter accepts both connector types without swapping. Built-in wavelength memory function recalls last-used settings on power-up. Auto power-off saves battery life during extended field sessions. Compact ergonomic design built with thermoplastic molding for durability in tough field environments. Powered by 3x AAA batteries for easy replacement anywhere. An indispensable tool for every ISP fiber technician performing installation verification, splice loss measurement, and fiber link troubleshooting.
