General characteristics of JW3302XR OTDR
JW3302XR optical time domain reflectometer is a multifunctional test instrument designed for FTTx network. It is mainly used to measure the length, transmission loss, joint loss and other physical properties of optical fiber, and to locate the event point and fault point in the optical fiber line. It is widely used for engineering construction, maintenance test and emergency repair in optical fiber communication system, as well as fiber optic cable development and production test.
In addition to OTDR function, JW3302XR OTDR can also be equipped with optical power meter, light source, visual fault location (VFL) and vibration detection function.
