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....

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...

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...

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 ...

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 ...

Difference between G652 fiber and G654 fiber
Mar 18 , 2022
G.652 optical fiber is the most widely used optical fiber. At present, except for fiber-to-the-home (FTTH) home optical cables, almost all optical fibers used in long-distance and metropolitan areas are G.652 optical fibers. From the perspective of light energy distribution, the optical signal in the single-mode fiber is not only transmitted in the core, but also in the cladding. In ...

What is the difference between fiber patch cords and pigtails?
Apr 01 , 2022
The difference between the two is that the pigtail is used to connect the optical cable and the jumper, and the jumper is to connect the pigtail and the terminal equipment. Optical fiber jumper is a jumper used from equipment to optical fiber cabling link, also known as optical fiber connector, which has a thicker protective layer and is generally used in the connection between optical transceiver...

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...

Maintenance of Fiber Fusion Splicer
Jun 17 , 2022
Clean the fiber V-groove If there is dirt in the optical fiber V-groove, the reference position of the optical fiber will change and the fusion loss will increase. It is recommended to clean the V-groove regularly. Clean the V-groove with a cotton swab dipped in alcohol to remove oil stains and dust. If there is large dirt that is difficult to remove, push the cut bare optical fiber in one directi...
