Overview - Handheld Optical Time Domain Reflectometer

This Optical Time Domain Reflectometer (OTDR) is an ideal instrument designed for testing FTTx networks. It operates at wavelengths of 1310 and 1550 nm and provides both auto and manual measurement modes. It measures the physical characteristics of optical fiber, such as the length, the transmission loss and the splice loss. It offers real time testing and provides a convenient visible fault location (VFL) function. This OTDR is widely used in the manufacture, construction and maintenance in optical fiber communication systems.
