Pigtail is an important component of an optical communication system. It is mainly used to realize the interconnection of optical ports between devices and the interconnection between devices and optical fiber cores. Different from conventional cables, pigtail core wires are easy to break and have weak tensile resistance, and there is no mature on-site processing solution for interface components, so pigtails of suitable length cannot be produced on-site according to the actual distance. Therefore, in practical applications, pigtails are usually processed and manufactured in a factory according to a certain nominal length series. During on-site installation and construction, engineers can choose pigtails that are longer than the actual distance. Because pigtails have the characteristics of discrete length and easy damage, pigtail reeling is the core link in pigtail installation, transport, and storage.
The inner core of the pigtail is made of silica glass fiber to carry the optical path. The fiber body is fragile and easy to break. The main line is usually a 48-core ADSS optical cable. These pigtails need to be sheathed in corrugated pipes and placed in the floor compartment or cable interlayer. There is no effective tool in the traditional pigtail threading method. The operation and maintenance personnel use the traditional brute force method to pass the pigtail through the corrugated pipe, which will cause more damage to the fiber jumper and cause a high probability of service interruption.
