With the development of the times, the improvement of the economy, and the development of science and technology, jumpers have been applied to our lives. There are many types of jumpers and pigtails. The main difference between jumpers and pigtails is that only one end of the pigtail has a connector. There are connectors at both ends of the jumper. Generally speaking, the jumper is cut from the middle to form two pigtails. So what is the difference between fiber jumper and fiber pigtail? The following Huijue Network will give you detailed answers!
What are jumpers and pigtails?
The jumper is a cable directly connected to the desktop computer or equipment to facilitate the connection and management of the equipment. The jumper has a thick protective layer and is often used between the terminal box and the optical transceiver.
Only one end of the 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.
Specifications and types of jumpers and pigtails
Jumpers are generally distinguished by single-mode and multi-mode in data transmission equipment. The color of single-mode jumpers is usually yellow, and there are two wavelengths, 1310nm and 1550nm, and the transmission distances are 10km and 40km respectively; 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 optical fiber connector, reinforced with a metal sleeve, and fixed by a turnbuckle.
SC type jumper: rectangular connector, the fixing method is a plug-in pin-bolt type, no need to rotate.
ST-type jumper: round connector, snap-in connection, and the fixing method is a turnbuckle.
LC type jumper: square connector, fixed method is made of 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:
Bundled pigtail: This kind of pigtail is also called pigtail bundle, which is composed of Corning tight-buffered optical fiber, aramid fiber strengthening element and flame-retardant PVC protective sheath. Compared with other types of pigtail 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 kind of 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 dense protective sleeve and waterproof sealing joint, it is suitable for harsh environments.
Application of Jumper and Pigtail
The jumper is mainly used for the connection between the optical fiber distribution frame or the optical fiber information socket to the switch, the connection between the switch and the switch, the connection between the switch and the desktop computer, and the connection between the optical fiber information socket and the desktop computer, which can be applied for the management, equipment room, and workspace subsystems. Pigtails are mainly used in optical fiber communication systems, optical fiber access networks, optical fiber data transmission, optical fiber CATV, local area network (LAN), test equipment, optical fiber sensors, serial servers, FTTH/FTTX, telecommunication networks and pre-terminated installations.
Precautions for jumpers and pigtails
The transceiver wavelengths of the optical modules connected by jumpers must be the same. Generally, the short-wave optical modules are equipped with multi-mode jumpers, and the long-wave optical modules are matched with single-mode jumpers to ensure the accuracy of data transmission.
During the wiring process of the jumper, reduce the winding as much as possible, which can reduce the attenuation of the optical signal during the transmission process.
The connector of the jumper should be kept clean. After use, the connector should be sealed with a protective cover to prevent oil and dust from entering. If it is stained, it should be cleaned with a cotton swab dipped in alcohol.
The pigtail is relatively slender. The cross-section of the pigtail is at an angle of 8 degrees. It is not resistant to high temperature and will be damaged if it exceeds 100 ° C. Therefore, it should be avoided in high temperature environments.
