The general procedures for handling submarine cable incidents are as follows:1. The spread spectrum time domain reflectometer (SSTDR) is also used to locate the fault location. The instrument uses the principle of time-domain reflection. It transmits and receives a set of signals first, because a ca

OTDR blind spot causes and solutionsThe full name of OTDR in English is Optical Time Domain Reflectometer, which means optical time domain reflectometer in Chinese. The main principle of its work is the use of pulses of light transmitted in the fiber Rayleigh scattering and Fresnel reflection produc

In order to accurately measure fiber length and decay when using OTDR, the relevant parameters must be set correctly before starting the test. The main parameters are: refractive index, pulse broadband and average time; At the same time, how to use the cursor to accurately pick points is also crucia

VFL Visual Fault Locator is the most commonly used, easy to carry and easy to operate. Use a Visual Fault Locator to illuminate the optical fiber connector in the direction of the optical cable, and adjust the button to emit light all the time or pulse light.

Optical Optical Time-domain reflectometer (OTDR) is a necessary optical fiber testing tool for analyzing the performance of optical fibers by using light backscattering technique. It can test fiber loss and locate breakpoints, splices, and connectors in fiber networks. However, there is a“Blind spot

Ada: doing fiber optic cable construction will definitely come into contact with such equipment as optical power meter and OTDR (optical time domain reflectometer). Many users do not understand why the optical power meter needs to be used to test the optical loss after testing the OTDR? Does OTDR no

The development of optical fiber communication has played an important role in China's economic construction. Optical fiber communication has incomparable advantages: the transmission frequency is wide and the loss is less. The construction of optical fiber communication started in the 1990s and has
