Fiber optic cable fusion steps and three precautions
Those who do optical fiber engineering should know that optical fiber fusion splicing is an important process with the largest amount of work and the most complex technical requirements in the optical fiber transmission system, and its quality directly affects the transmission quality and reliability of optical fiber lines. It is extremely important to have an efficient method and correct splicing steps. Today we will learn about the fusion splicing steps and three precautions for optical fiber cables
Fusion splicing steps for fiber optic cables
The first step is to strip the optical cable and fix the optical cable in the splice box. When fixing multi-bundle tube-layer optical cables, since the fibers need to be coiled in layers, each bundle of tubes should be placed in sequence to avoid twisting. Pass the optical cable into the splice box, and when fixing the steel wire, be sure to press it tightly so that there is no looseness.
In the second step, pass the optical fiber through the heat shrinkable tube. Separate different tube bundles and optical fibers of different colors, and pass them through the heat-shrinkable sleeve. The fiber optic cable with the coating layer stripped off is very fragile. Use a heat shrinkable sleeve to protect the fiber optic connector.
The third step is to turn on the power of the fusion splicer and select the appropriate splicing method. The power supply of the fusion splicer has two kinds of DC and AC, and it should be switched reasonably according to the type of power supply current.
The fourth step is to make the fiber end face. The quality of the optical fiber end face will directly affect the splicing quality, so it is necessary to make a qualified end face before fusion splicing.
The fifth step is to clean the bare fiber. Tear the cotton into small pieces with a flat surface, stick a little alcohol, clamp the stripped optical fiber, and wipe along the axis of the optical fiber. Use moderate force and use different parts of the cotton each time. and level, so that the utilization rate of cotton can be improved.
The sixth step is to cut the bare fiber. First, clean the cutter and adjust the position of the cutter. The cutter should be placed steadily. When cutting, the movement should be natural and stable, not heavy or light. Avoid bad end faces such as fiber breaks, bevels, burrs and cracks.
Precautions for fusion splicing of optical fiber cables
- Cleaning, inside and outside of the optical fiber fusion splicer, the optical fiber itself, the most important parts are the V-shaped groove, the optical fiber presser foot and other parts.
- When cutting, ensure that the cutting end face is 89°±1°, which is approximately vertical. When placing the cut optical fiber at the designated position, the end face of the optical fiber should not touch any place. If it is touched, we need to clean it again. Cutting: Emphasize cleaning first and then cutting!
- When putting the optical fiber in its position, don’t be too far or too close, 1/2 place, proficiency!
The above are the fusion splicing steps and three precautions for you to explain to everyone. We must understand and master the laws of the optical fiber fusion process. The development of fiber optic cable industry, data center mpo fiber optic box and other industries has greatly stimulated my country’s communications.
