Pigtail refers to an optical connection line with an optical fiber active connector installed at one end of an optical fiber or optical cable, and an optical fiber or optical cable at the other end. Dividing an optical jumper into two becomes two optical pigtails. Optical pigtails are usually used for the terminal of the optical path (such as the terminal point to the actual test result box, the splice tray in the distribution equipment, etc.), Or the extraction of optical devices (such as optical splitters, lasers, detectors, etc.). The pigtail length usually does not exceed 2 meters.
Same as the optical jumper, when the connecting line is an optical cable (mostly an indoor optical cable) and tested by a standard test line, it is called an optical cable pigtail, and when the connecting line is an optical fiber (usually a tight-buffered optical fiber), it is called an optical fiber pigtail. There is no special product standard for optical pigtails. Most buyers and sellers switch to "any type" in the form of optical jumpers when they deliver goods. The quality acceptance is the same as optical jumpers, and the standard for optical fiber active connectors is also applied.
How to identify loose pigtail
After checking this type of pigtail, we found that there are two styles of pigtails on the market, which we call loose pigtails and tight pigtails.
If it is loose between the sheath and the coating, it is called a loose pigtail, and if it is fastened between the sheath and the coating, it is called a tight pigtail. Now basically all splitters on the market are loose sleeve type; some jumpers are also loose sleeve type;
How to Splice Loose Tube Pigtails
1. When splicing tight sleeve pigtails, the pressure plate of the fusion splicer is pressed against the sheath, because the sheath and the coating layer are fastened, so when the pressure plate drives the sheath to move, the optical fiber also follows the movement, and the fusion can be completed;
2. When splicing loose sleeve pigtails, please strip the sheath a little longer, let the pressure plate press on the coating layer instead of the sheath, and the problem will be solved;
Note: let the pressure plate press the coating layer, not the bare fiber inside. So just pay a little attention when stripping the fiber.
