Pigtails

Pigtails are important components of optical communication systems, mainly used to achieve the interconnection of optical ports between devices and the interconnection of devices and optical cable cores. Unlike conventional cables, pigtail cores are easy to break and have weak tensile strength. There is no mature on-site processing solution for interface components, and it is impossible to produce pigtails of appropriate length on-site according to the actual distance. Therefore, in practical applications, pigtails are usually processed and manufactured in factories according to a certain nominal length series. During on-site installation and construction, engineers can select pigtails with a length greater than the actual distance. Because pigtails have the characteristics of discrete length and easy damage, pigtail coiling is the core link in the installation, return and storage of pigtails. The inner core of the pigtail uses silica glass fiber to carry the optical path. The fiber body is fragile and easy to break. The trunk line is usually a 48-core ADSS optical cable. These pigtails need to be put into a corrugated tube and laid in the floor compartment or cable interlayer. There is no effective tool to assist in the traditional pigtail threading method. The operation and maintenance personnel use the traditional brute force method to pass the pigtail through the corrugated tube, causing more jumpers to be damaged, resulting in a high probability of service interruption.
