Pigtail cable, also known as pigtail cable, has a connector on one end, and the other end is a broken end of a fiber optic cable core, which is connected to other fiber optic fiber core by welding. It is often found in the fiber terminal box, used to connect the fiber optic cable to the fiber transceiver (between the coupler, jumper, etc.).

There are two main types of optical fibers.
There are two main types of optical fibers: Single-mode Fiber: Generally, fiber jumpers are shown in yellow, and connectors and protective sleeves are shown in blue. The transmission distance is long. Multi-mode Fiber: Generally, fiber jumpers are shown in orange, and some are shown in gray. Connectors and protective covers are shown in beige or black. The transmission distance is shorter.
