What is Fiber Optic Pigtail

Posted on by FS.COM

Fiber optic pigtail is a fiber cable end with fiber optic connectors at only one side of the cable while leaving the other side no connectors, so that the connector side can be linked to the equipment and the other side can be melted with optical cable fibers.

Fiber optic pigtails are used to achieve accurate mounting for precision alignment of fiber optical components. They are usually used with fiber optic management equipment like ODF, splice closures and cross cabinets.

A fiber pigtail is a single, short, usually unbuffered, optical fiber that has an optical connector pre-installed on one end and a length of exposed fiber at the other end. The end of the pigtail is stripped and fusion spliced to a single fiber of a multi-fiber trunk. Splicing of pigtails to each fiber in the trunk “breaks out” the multi-fiber cable into its component fibers for connection to the end equipment.

Fiber pigtails can have female or male connectors. Female connectors could be mounted in a patch panel, often in pairs although single-fiber solutions exist, to allow them to be connected to endpoints or other fiber runs with patch fibers. Alternatively they can have male connectors and plug directly into an optical transceiver.

As the fibers need to have connectors fitted before they can attach to other equipment. Fiber pigtails can be one of the common solutions for fiber cable termination, which is the addition of connectors to each optical fiber in a cable.

Fiberstore supplies 10G 50/125, 62.5/125, 50/125 multimode optic pigtail with SC, ST, FC, LC MT-RJ, SC/APC, FC/APC, E2000 fiber optic connectors. Fan-out fiber optic pigtail is a multi fiber cable assembly. It is usually made from a multi fiber count cable, in the middle of which we use the splitting kits to make the fan-out pigtails. Such cable is usually 1XN structure, like MTP to 12 LC. Sometimes there are also NXN types, like 12LC to 12LC. Usually the simplex fiber optic pigtails that used inside management equipment use 0.9mm outer diameter cable. There is waterproof fiber optic pigtails used for outdoor applications. This fiber optic pigtail is with thick PE jacket and big diameter. For example, ribbon fan-out patch cord provides a stable and reliable connection for single mode fiber.
