When the fiber is broken, we do not call it repair, we call it fusion. Just like the electric welding of the iron pipe, with a special machine, it is the fiberglass filaments that are fused together!
Generally, companies that manufacture and optical-related products will set up an optical fiber fusion splicer. Today, we will talk about fusion splicing.
The structure of the fiber:
Use a tool to remove the coating layer, wipe the alcohol clean, cut the end face flat, and fix the two end faces to be welded with a V-groove.
The fusion splicer has two electrodes, generally a high voltage electrode and a low voltage electrode.
Electrode discharge, the temperature of the arc is higher
The end face of the optical fiber is melted after high temperature, just like plastic becomes soft and sticky when it encounters fire.
Quickly dip the two melted ends together. "melted" into

What is the numerical aperture of the fiber patch cord?
What is Numerical Aperture. It is a dimensionless value under the optical system, which is used to measure the angular range that the optical system can collect and transmit light, expressed in NA.
Below this parameter, the well-known single-mode fiber jumper, 9/125um, has no numerical aperture. When the single-mode fiber jumper transmits the wavelength of 1310nm, its attenuation value is below 0.36dB/KM; When transmitting a wavelength of 1550nm, the attenuation value is less than 0.22dB/KM.
Fiber Jumper
The value of numerical aperture is usually reflected in the multimode fiber jumper, of which 50/125um is plus 0.200NA, minus 0.015NA; 62.5/125um is plus 0.275NA, minus 0.015NA. Multimode fiber patch cords can meet this parameter.
