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 ...

The Classifications of Optical Fiber Fusion Splicers
Jul 24 , 2020
Before the fusion of the optical fiber fusion splicer, according to the material and type of the optical fiber, the key parameters such as the pre-melting main melting current and time and the fiber feeding amount are set. During the welding process, the “V” shaped groove, electrode, objective lens, welding chamber, etc. of the welding machine should be cleaned in time. Observe the presence or abs...

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 ...

Introduce of Optical Power Meters
Aug 31 , 2020
Introduce of Optical Power Meters An optical power meter (or laser powermeter) is an instrument for the measurement of the optical power (the delivered energy per unit time) in a light beam, for example a laser beam. Typically, it allows for power measurements only with a relatively low bandwidth, and will e.g. display only the average power when receiving a pulse&nbs...

What is the difference between single-mode fiber and multi-mode fiber? Which one to choose?
Sep 21 , 2020
The first is to introduce the difference between multimode fiber and single mode fiber: Multimode fiber The optical signal in multimode fiber propagates through multiple channels; it is usually recommended to be used when the distance is less than miles. The effective distance of multimode fiber from transmitter to receiver is about 5 miles. The usable follow-up is also affected by the type and qu...

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 Notes When Using OTDR
Nov 26 , 2020
1. Simple judgment of fiber quality: Under normal circumstances, the slope of the main body of the light curve (single disk or several optical cables) tested by OTDR is basically the same. If the slope of a certain section is large, it indicates that the attenuation of this section is large; if the main body of the curve is of irregular shape, the slope fluctuation is large. Bending or arcing indi...
