When it comes to fiber optics, we naturally think of patch cords and pigtails. Usually people don't know the difference between the two. Let's talk about the difference between carrier-grade single-mode fiber patch cords and pigtails. Let's find out together.
Carrier-grade single-mode fiber patch cords
1. What are jumpers and pigtails?
Patch cords are cables that connect directly to a desktop computer or device to facilitate device connection and management. Jumpers have a thicker protective layer and are usually used between junction boxes and optical transceivers. Pigtails have a connector on one end and a fiber optic connector on the other end. It is soldered to the core of other fiber optic cables, usually found in fiber optic junction boxes.
2. Specifications and types of jumpers and pigtails
Patch cords are usually distinguished by carrier-grade single-mode fiber patch cords and multi-mode in data transmission equipment. The color of the single-mode patch cord is usually yellow, and there are two wavelengths, 1310nm and 1550nm, respectively, and the transmission distance is 10km and 40km, respectively. The color of the multimode patch cord is usually orange, the wavelength is 850nm, and the transmission distance is 500m.
According to the type of joint, it can be divided into the following types:
FC type jumper: circular optical fiber connector, additional metal sleeve for reinforcement, the fixing method is turnbuckle.
SC-type jumper: rectangular connector, fixed by plugging and unplugging, without rotation.
ST-type jumper: circular connector, with a snap connection, and the fixing method is a turnbuckle.
LC-Type Patch Cords: Square connectors that are secured in a convenient modular jack (RJ) latch principle. 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, LC bundled pigtails and ST bundled pigtails pigtail.
Carrier-grade single-mode fiber patch cord application scenarios
In addition to these, it can be divided into the following types:
Ribbon Pigtail: Ribbon pigtail is the same as bundle pigtail. Both are multicore pigtails. Ribbon pigtails consist of 12 fibers with one end for soldering and one end with a connector.
Armored pigtail: The outermost layer of this pigtail adds a metal protective cover to the regular pigtail, so it is more durable than ordinary pigtails.
Optical fiber pigtail: low insertion loss, high return loss, good interchangeability, repeated plugging and unplugging, very convenient to use. Waterproof Pigtail: With a sturdy protective sleeve and waterproof sealing connector, it can be used in harsh environments.
3. Application of jumper and pigtail
Jumpers are mainly used for fiber patch panels or fiber information sockets to connect switch connections, switch connections, desktop computer connections, and fiber information sockets to desktop computer connections, suitable for management, equipment rooms, and workspace subsystems. Pigtails are mainly used in optical fiber communication systems. Fiber Access Networks, Fiber Data Transmission, Fiber CATV, Local Area Networks (LANs), Test Equipment, Fiber Sensors, Serial Servers, FTTH/FTTX, Telecom Networks and Pre-terminated Installations.
The above is the difference between patch cords and pigtails. In fiber optic transmission systems, pigtails and carrier-grade single-mode fiber patch cords are the main tools. It will not work if missing. There are also high demands on data transmission. The quality of the ferrule, the technology and method of production all determine the stability of data transmission.
