The Structure And Classification Of Optical Fiber Jumper Are Described in Detail

Optical fiber jumper (also known as optical fiber connector) means that both ends of the optical cable are installed with connector plugs to achieve optical active connection; One end with a plug is called a pigtail. Fiber jumper is similar to coaxial cable, only there is no mesh shielding layer. At the center is a glass core through which light travels. It is mainly used to realize the non-permanent fixed connection between the equipment, the equipment and the instrument, the equipment and the optical fiber and the optical fiber, and is an indispensable passive device in the optical fiber communication system.
At present, with the rapid development of Internet information, optical fiber has been widely used because of its high speed and fast speed. As an important device used to realize the active connection of optical paths, optical fiber jumper has always been an important guest of data center, optical fiber to the home, local area network and other industries. Since the universal application of optical fiber jumper, most people still have many questions and problems about the basic knowledge of optical fiber jumper. Next, we will have an in-depth understanding of the structure, classification, characteristics and applications of optical fiber jumpers.
Structure of optical fiber jumper
In a multimode fiber, the diameter of the core is 50μm to 65μm, roughly the thickness of a human hair. The diameter of the single-mode fiber core is 8μm~10μm. The core is surrounded by a glass envelope with a lower refractive index than the core to keep the fiber inside the core. On the outside is a thin plastic jacket to protect the envelope.

Classification of optical fiber jumpers
Fiber jumper according to the different transmission media can be divided into common "single mode fiber jumper" and "multi-mode fiber jumper".
Single-mode fiber: the general fiber jumper is shown in yellow, and the connector and protective sleeve are blue; The transmission distance is long.
Multimode fiber: the general fiber jumper is expressed in orange, and some are expressed in gray, and the connector and protective case are beige or black; The transmission distance is short.
According to the different connector structure, it can be divided into: FC fiber jumper, SC fiber jumper, ST fiber jumper, LC fiber jumper, MTRJ fiber jumper, MPO fiber jumper, MU fiber jumper, SMA fiber jumper, FDDI fiber jumper, E2000 fiber jumper, DIN4 fiber jumper, D4 fiber jumper and other forms. Common optical fiber jumpers can be divided into FC-FC, FC-SC, FC-LC, FC-ST, SC-SC, and SC-ST....
① FC optical fiber jumper: The external strengthening method is metal sleeve, tightening method is turnbuckle. Generally used on the ODF side (most used on the distribution frame)
(2) SC type optical fiber jumper: connected to the connector of the GBIC optical module, its shell is rectangular, fastening method is to use the plug and bolt type, do not need to rotate. (Most used on routers and switches)
(3) ST type optical fiber jumper: often used in optical fiber distribution frame, shell is round, fastening method is turnbuckle. For 10Base-F connections, the connector is usually of type ST. Commonly used in optical fiber distribution frames)
LC type optical fiber jumper: the connector connecting the SFP module, it is made of easy to operate modular jack (RJ) latch mechanism. (Commonly used routers)
