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...

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...

What is Large Diameter Fiber?
Aug 17 , 2023
Large Diameter Fiber (LDF) is a type of optical fiber that has a significantly larger core diameter compared to standard single-mode fibers. While traditional single-mode fibers typically have a core diameter of around 8-10 microns, LDF can have core diameters ranging from 50 to 400 microns or even larger. This increased core size allows LDF to transmit light over a larger area, enabling it to han...
