How to reduce the fusion splicing loss?
Apr 28 , 2022
The size of the loss is a very important technical indicator of the optical fiber fusion splicer. The lower the loss, the higher the precision of the machine, which can support longer distance fusion splicing. The more perfect the fusion point, the longer the service life. 1. The fiber cleaver cutting angle of the fiber is very important. At present, most of the optical fiber fusion splicers are f...

OTDR test with light
May 24 , 2022
What is OTDR test with light? When testing with the wavelengths of 1310nm, 1490nm and 1550nm of common OTDR, it is necessary to require that there is no communication optical signal in the line under test. Forcing the test with light will burn out the internal detector of the OTDR. With light test, the OTDR can still complete the test without interrupting the signal light in the line during the te...

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...
