Fiber optic patch cords and pigtails are two common fiber optic connections in fiber optic communications, and they have some differences in their uses and characteristics.
Fiber optic patch cords (Patch Cord): Fiber optic patch cords are usually used for short distance connections, connecting the fiber optic interfaces between devices, such as connecting the fiber optic ports between fiber optic transceivers (Transceiver) and network switches (Switch). Fiber optic patch cords are generally short, usually between a few meters and tens of meters in length. Fiber optic patch cords are usually divided into single-mode patch cords and multimode patch cords to accommodate different types of fiber optic transmission modes.
Pigtail: A pigtail is a section of optical fiber that is fixed in a fiber optic connection module (e.g., fiber optic connection box or optical module). Pigtails are generally long and the length can be customized as needed. One end of the pigtail is connected to the fiber optic connection module, and the other end is reserved for the bare fiber core, which is used to connect with other fibers. Pigtails are usually used in the construction and maintenance of fiber optic networks as a bridge between the fiber optic connection module and the fiber optic line.
