The steps of fusion fiber
Jul 22 , 2022
1) peel the optical cable, be careful not to hurt the tube bundle, and take about 30mm in stripping length. 2) pass the optical fiber through the heat-shrinkable tube. The stripped cable is fragile and uses heat-shrinkable bushings to protect optical fiber connectors. 3) turn on the fiber fusion splicer power and choose the appropriate welding mode. There are two kinds of fiber fusion splicer powe...

What is dynamic range of OTDR
Dec 15 , 2022
The dynamic range of an OTDR determines how long of a fiber can be measured. It is listed as a dB value — larger values generally mean longer distance measurement capability. A test pulse needs to be strong enough to get to the end of the fiber to be tested, and the sensor has to be good enough to measure the weakest backscatter signals which come from the end of a long fiber. The combination of t...
