What is a fiber optic pigtail?
Tail fiber, also known as pigtail or pigtail. This is a piece of fiber optic cable with an optical connector at one end and an open piece of optical fiber at other end. The end of connector is used to connect equipment, and other end is connected to another core of fiber optic cable by welding, which minimizes insertion loss. Connecting pigtails to distributed optical cables using a mechanical or welded connection can greatly simplify installation and maintenance of cable system.
While single pigtail solutions exist, pigtails can be made with female connectors mounted in pairs on patch panels for connection to end devices. In addition, pigtail also has a pin interface that can be directly connected to optical transceiver.
Types of fiber optic pigtails
Similar to fiber optic jumpers, there are many types of pigtails, such as single-mode, multi-mode, single-wire, two-wire, and more. Usually, color of multimode pigtail is orange, wavelength is 850nm, transmission distance is 500m. The color of single-mode pigtail is yellow, wavelength is 1310m and 1550m, and transmission distance is 10km and 40km. The figure below shows an exploded view of ST/SC/LC/FC pigtail.
In addition to common types of braids mentioned above, there are bun and ribbon braids, both of which are branched braids. In addition, there is a special waterproof pigtail. The waterproof pigtail is manufactured in strict accordance with IEC standard of International Electrotechnical Commission. It has low insertion loss, high return loss, good interchangeability and reproducible push-pull performance, and is very convenient to use. Waterproof pigtails with durable covers and waterproof sealed connectors for use in harsh environments.
