For communication workers working outdoors, the working environment in winter is relatively harsh. Rain and snow, windy weather, and foggy weather all bring great challenges to welding. The staff is shivering in the cold outside. The fusion splicer is also prone to failure. Today, I will give you some tips for using the fusion splicer in harsh environments and the points that should be paid attent...

Optical Time Domain Reflectometer (OTDR) is a mandatory fiber optic testing tool which uses light backscattering technologies to analyze optical fiber performance. An OTDR can test the light loss and locate the breaks, splices and connectors in fiber optic network. However, an OTDR has a “Dead Zone“ which can affect the test results. To overcome the limitation of this OTDR dead zone, an OTDR Launc...

1. Knowledge of OTDR extension cable The OTDR extension cable is similar to the optical fiber jumper. There is no fusion point in the middle of the optical fiber. During the optical fiber test, the OTDR extension cable is the insertion loss and reflectivity of the near-end connection and the far-end connection of the optical fiber line when using the OTDR measurement. It is mainly used to make up ...

What's OTDR launch cable box / OTDR Dead Zone Eliminator used for? An OTDR (Optical Time Domain Reflectometer) launch cable box, also known as an OTDR Dead Zone Eliminator, is used in fiber optic testing and troubleshooting. In fiber optic testing, the OTDR is used to measure the characteristics of an optical fiber, such as loss, length, and quality. However, OTDRs have a limitation called the "de...
