The knowledge and use of OTDR launch cable
Mar 04 , 2022
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 ...

Ten reasons for excessive splicing loss of optical fiber
Feb 23 , 2022
1. Choose the wrong optical fiber splicing program; for example, misselect the single-mode splicing program to multi-mode. 2. The cutting angle of the end face of optical fiber is too large. 3. The optical system is dirty, mainly the reflector and objective lens. 4. V-shaped slot dirty, optical fiber pressure foot dirty. 5. The aging of the electrode leads to the weak discharge intensity, and the ...

What are reflective and non-reflective events in otdr?
Jan 21 , 2022
1. The height of each point in the OTDR curve represents the backscattered light intensity at that location. When looking at the OTDR curve, you can see that the reflected signal is raised in some places, as if the optical power at the back is stronger than the front, which is impossible. Generally, this situation is the backscattering peak caused by the Fresnel reflection at the splicing, breakin...

How to solve these six problems encountered in the process of optical fiber fusion splicing?
Sep 29 , 2021
1. There are bubbles or cracks in the contacts during welding This situation may be due to poor fiber cutting, such as the end face is inclined, burrs, or the end face is not clean, and the fiber needs to be cleaned before the splicing operation; there is also a situation that the electrical electrode is aging and the electrode rod needs to be replaced. 2. The welding is too thick or the contact p...

Introduction and use of the optical cable identifier
Sep 17 , 2021
When using the optical cable identifier, the user only needs to tap the optical cable lightly to easily find the target. The built-in system of the instrument can convert the tapping information into audio and video signals. In other words, we can hear or see the target optical cable. Where. The optical cable identifier completely replaces the previous cutting, bending, freezing and other methods....
