What is Fusion Splicer And How to Splice Two Fibers?
May 22 , 2020
What is a fiber optical fusion splicer? Fusion splicer is to use high-temperature heat generated by electric arc and melt two optical fibers together at their end faces,to form single long fiber.More precisely, the fiber ends are initially brought in close contact,with a small gap in between. After heating them for a short while such that the surfaces melt, they are pushed together, such that the ...

Fusion Splicer Maintenance how to Clean its V-groove?
Jun 09 , 2020
Fusion splicer is a high precision equipment, it is very import to do the maintenance during daily work. V-groove is a V slot on the ceramic substrate of narrow width, easily to accumulate dust which will make the fiber move instability and cause a bad fusion, therefore, the V groove should be cleaned regularly. The following is the way of cleaning the V-groove

How To Use The Optical Power Meter?
Aug 20 , 2020
Optical power meter refers to an instrument used to measure absolute optical power or the relative loss of optical power through a section of optical fiber. Simply put, it is to measure the attenuation of the optical signal after fiber transmission. Simple instructions: 1. When measuring the absolute optical power with the optical power meter, just connect the light source and look at the value in...

The maintenance and replacement of electrodes for optical fiber fusion splicer
Aug 28 , 2020
The electrode rod is an important part of the welding machine. Discharge welding is completed by the electrode rod. However, many people do not understand that the electrode rod is a consumable and needs to be replaced when it reaches a certain life span. Although the metal itself is hard and will not be worn by external forces, it needs to withstand high temperature discharge for a long time. At ...

The Basic Principles of OTDR
Oct 15 , 2020
OTDR is called Optical Time Domain Reflectometer, which injects narrow light pulses into the fiber end face as a detection signal. When the light pulse propagates along the fiber, the backscattered part of Rayleigh scattering everywhere will continue to return to the incident end of the fiber. When the optical signal encounters a crack, Fresnel reflection will occur, and the back reflected light w...

Cleaning of fusion splicer's microscopes (objective lenses)
Oct 23 , 2020
The fusion splicer uses the image processing system to observe the optical fiber. If the microscopic lens becomes dirty, it will affect the normal optical fiber observation, resulting in poor welding effect. Therefore, the lenses of the two microscopes should be cleaned regularly to keep the microlenses clean and tidy. The specific process is as follows: (1) turn off the power supply of the f...

The simple failure analysis and elimination of fusion splicer
Dec 23 , 2020
1. During the splicing process, the fusion splicer displays "fiber not found or the end face of the fiber is untidy". This is mainly caused by the surface of the optical system being contaminated. The protective glass (located under the electrode) should be cleaned with absolute alcohol, and the lens on the fiber cover should be cleaned at the same time. Wait until the alcohol is dry before procee...

Daily maintenance of fusion splicer
Apr 09 , 2021
In the fusion state, the optical fiber advancement stops and the machine does not perform fusion operation. The reason is that the V-groove is dirty and must be cleaned. After closing the windproof cover, the optical fiber will not push forward. Reason: 1. The bare optical fiber is placed too far from the electrode or beyond the electrode, please replay the optical fiber. 2. The objective lens has...
