An OTDR launch cable box lets you measure the first connector and splice accurately by moving them out of the OTDR dead zone. Learn how it works, 1000m vs 2000m, and how to set it up.
The right OTDR depends on the fiber in the network. Learn how single-mode and multimode OTDRs differ, which wavelengths they use, and when a quad-wavelength model makes sense.
An OTDR trace tells the full story of a fiber link. Learn how to read the slope, identify connectors, splices, bends, ghosts and the fiber end, and avoid common interpretation mistakes.
The Comway MAX-600-M4 is a professional quad-wavelength OTDR supporting both singlemode (1310/1550nm) and multimode (850/1300nm) fiber in a single handheld unit — ideal for FTTH contractors, data center teams, and telecom engineers.
