Difference between Fiber Pigtail & patch cords

Optical fiber patch cords are made from either single or multi-fiber cables (usually rated for indoor use) and connected at each end with an optical connector (either single fiber or multiple-fiber connector). Sometimes patch cords are called jumpers, especially if they are simplex or dulex. The connectors are selected to mate with the interfacing equipment or cable connectors. The important idea is that the cable has a connector at each end. The fiber can be either tight or loose buffered and the cable can be made of various diameters (1.2 mm to 3.0 mm are common). The patch cord may have one type of connector (ST FC, SC, LC, etc) on one end and a different connector on the other as long as all the fibers are connectorized on each cable end – this is a transition jumper. Patch cords are commonly used to connect ports on fiber distribution frames (FDFs).

A fiber pigtails is a cable (like a pach cord or jumper) with only one end terminated with an optical connector. Patch cords are often cut into shorter lengths to make two pigtails. Pigtails are found anywhere, but more commonly in optical assemblages or optical components (in a box)
