Detailed explanation of the structure and classification of fiber optic patch cords

Fiber optic jumpers (also known as fiber optic connectors) refer to optical cables with connector plugs installed on both ends to achieve active connection of the optical path; a plug installed at one end is called a pigtail.Fiber optic patch cords are similar to coaxial cables, except without the mesh shield.At the center is a glass core through which light travels.It is mainly used to realize non-permanent fixed connections between equipment, equipment and instruments, equipment and optical fibers, and optical fibers in the system. It is an indispensable passive component in the optical fiber communication system.With the rapid development of Internet information, optical fiber has been widely used due to its high speed and high speed. As an important component for realizing active connection of optical paths, its optical fiber patch cord has always been the preferred choice in data centers, optical fiber to the home, local area networks and other industries. Important guests, since the popularity of fibe.

Classification of Fiber Optic Jumpers

Fiber optic jumpers can be divided into common "single-mode fiber optic jumpers" and "multi-mode fiber optic jumpers" according to the different transmission media.

Single mode fiber: Generally, fiber jumpers are represented in yellow, and connectors and protective sleeves are blue; The transmission distance is relatively long.

Multimode Fiber: Generally, fiber optic jumpers are represented in orange, while others are represented in gray. The connectors and protective sleeves are in beige or black; The transmission distance is relatively short.

According to the different connector structures, it can be divided into various forms such as FC fiber optic patch cords, SC fiber optic patch cords, ST fiber optic patch cords, LC fiber optic patch cords, MTRJ fiber optic patch cords, MPO fiber optic patch cords, MU fiber optic patch cords, SMA fiber optic patch cords, FDDI fiber optic patch cords, E2000 fiber optic patch cords, DIN4 fiber optic patch cords, D4 fiber optic patch cords, etc. Common fiber optic jumpers can also be divided into FC-FC, FC-SC, FC-LC, FC-ST, SC-SC, SC-ST, etc

① FC type fiber optic jumper: The external reinforcement method is to use a metal sleeve, and the fastening method is to use a screw buckle. Usually used on the ODF side (most commonly on distribution frames)

② SC type fiber optic jumper: a connector that connects GBIC optical modules. Its outer shell is rectangular and fastened using a plug and pull pin latch type, without the need for rotation. (Most commonly used on router switches)

③ ST type fiber optic jumper: commonly used in fiber optic distribution frames, with a circular outer shell and a screw buckle fastening method. (For 10Base-F connections, connectors are usually ST type. Commonly used in fiber optic distribution frames)

④ LC type fiber optic jumper: a connector for connecting SFP modules, made using a modular jack (RJ) latch mechanism for easy operation. (commonly used in routers)
