12-core bundle pigtail: Bundle pigtail, also known as pigtail bundle, only has a connector at one end, and the other end is a broken end of an optical fiber, which is connected to the core of other optical cables through splicing. It often appears in fiber optic terminal boxes. Inside, used to connect optical cables and terminal equipment. Pigtails are divided into multi-mode pigtails and single-mode pigtails.

Multi-core optical cables (such as 4-core, 6-core, 8-core, 12-core) can be divided into sectors (bundles) and installed with connector plugs to realize multi-core optical cable splitting connection, which facilitates indoor connections and dense distribution frames (ODF). Install. Waterproof tail cable assemblies are generally used in harsh outdoor environments and have high reliability for devices. The multi-mode pigtail is orange, has a wavelength of 850nm, and a transmission distance of 500m, and is used for short-distance interconnection. The single-mode pigtail is colored and has two wavelengths, 1310nm and 1550nm. The transmission distances are 10km and 40km respectively. It consists of 12 pigtails, the colors are: blue, orange, green, brown, gray, white, red, black, yellow, purple, pink, light blue. Insertion loss: ≤0.2dB Return loss: ≥60dB Operating temperature: -40℃～80℃ Repeatability: ≤0.1dB Interchangeability: ≤0.2dB Plugging and unplugging times: >1000 times Tensile strength: 0~15Kg.
12-core bulk pigtail: just 12 ordinary pigtails. 12-core bundled pigtail: equivalent to peeling off the outer skin of 12 ordinary pigtails and then “bundling” them together to make one, 12 heads, 12 types color. This multi-12-core ribbon pigtail used in the integrated splicing tray: The pigtail made of 12-core ribbon fiber also has 12 heads. Fiber optic connectors (also known as jumpers) refer to connector plugs installed on both ends of the light to achieve active connection of the optical path; a plug installed on one end is called a pigtail. The connection types of single-mode optical fiber connectors include ST, SC, FC, LC, MU, D4, SM4, FDDI, MT-RJ and other indicators, and the end contact methods include PC, UPC and APC types. A jumper with different connector types or contact surfaces at both ends is called a single-mode patch cord. It consists of 12 pigtails, the colors are: blue, orange, green, brown, gray, white, red, black, yellow, purple, pink, light blue. One is pull-out type, with a splicing disk inside the machine frame. , equipped with 12-core bundled pigtails and couplers (this is called optical fiber distribution frame), there are 12 cores, 24 cores, 48 cores, 72 cores, and 96 cores. There is also a terminal box type, which can be installed using LC, SC, ST, FC couplers and 19-inch rack-mounted installation.
