How to splicing loose pigtails

I often receive calls from many friends who splicing optical fibers, saying that in the project, the optical fiber to pigtail (jumper), pigtail to pigtail, and pigtail to pigtail will not be spliced; or the loss will be large, but the picture Like thinning occurs. The fiber-to-fiber fusion splicing is normal. Including the use of imported fusion splicers also have the above problems.

Splicing loose pigtails

1. If you identify loose pigtails:

After examining this type of pigtail, we found that there are two styles of pigtails on the market now, which we call loose pigtails and tight pigtails.

If the sheath and the coating are loose, it is called a loose pigtail, and if the sheath and the coating are tight, it is called a tight pigtail. Now basically all splitters on the market are loose type; some jumpers are also loose type;

2. How to splicing loose pigtails:

1. When splicing the tight-sleeve pigtail, the pressing plate of the fusion splicer is pressed against the sheath shown in the picture. Because the sheath and the coating layer are fastened, when the pressing plate drives the sheath to move, the optical fiber also follows the movement. Can complete welding;

2. When splicing loose pigtails, please strip the sheath longer so that the pressure plate is pressed on the coating layer instead of the sheath, and the problem will be solved easily;

Note: let the pressure plate press the coating layer, not the bare fiber inside. So be careful when stripping fibers.
