What are fiber optic jumpers and fiber pigtails, what are the specifications and types of fiber optic jumpers and fiber pigtails? Optical fiber jumper is a cable that is directly connected to a desktop computer or device to facilitate the connection and management of the device. The jumper has a thicker protective layer and is often used between the terminal box and the optical transceiver.
Only one end of the fiber pigtail has a connector, and the other end is an optical fiber connector, which is connected to other optical fiber cores in the form of fusion splicing, and generally appears in the optical fiber terminal box.
What are the specifications and types of fiber optic jumpers and fiber pigtails?
Jumpers are generally distinguished by single-mode and multi-mode in data transmission equipment. The color of single-mode jumpers is usually **, there are two wavelengths, 1310nm and 1550nm, and the transmission distances are 10km and 40km respectively; multimode jumpers The color is usually orange, the wavelength is 850nm, and the transmission distance is 500m. According to the type of joint, it can also be divided into the following types:
FC type jumper: round fiber optic connector, reinforced by an additional metal sleeve, and the fixing method is a turnbuckle.
SC type jumper: Rectangular connector, fixed way is plug-in pin latch type, no need to rotate.
ST-type jumper: round connector, using snap-in connection, the fixing method is a turnbuckle.
LC type jumper: square connector, fixed by the modular jack (RJ) latch principle which is easy to operate.
The types of pigtails mainly include single-core pigtails, double-core pigtails, 4-core pigtails, 12-core bundled pigtails, 12-color bundled pigtails, SC bundled pigtails, FC bundled pigtails, and LC bundled fibers Pigtails and ST bundled pigtails. In addition to these can be divided into the following types:
Bundle pigtail: This kind of pigtail is also called pigtail bundle, which is composed of Corning tight-sleeve optical fiber, aramid fiber strengthening element and flame-retardant PVC protective sheath. Compared with other types of pigtails, It is more popular and widely used.
Ribbon pigtail: The ribbon pigtail is the same as the bundled pigtail, both of which are multi-core pigtails. The ribbon pigtail contains 12 core fibers, one end is used for fusion splicing, and the other end is equipped with a connector.
Armored pigtail: The outermost layer of this pigtail has an extra layer of metal protective sheath than conventional pigtails, so it will be more durable than ordinary pigtails.
Optical fiber pigtail: low insertion loss, high return loss, good interchangeability and repeatability, very convenient to use.
Waterproof pigtail: with a dense protective sleeve and waterproof sealing connector, suitable for harsh environments.
