1.structure

Optical fiber jumper (also known as optical fiber connector) means that both ends of the optical cable are equipped with connector plugs.

It is used to realize the active connection of the optical path; a plug at one end is called a pigtail. Optical Fiber Patch Cord/Cable is similar to coaxial cable, except that there is no mesh shielding layer. In the center is the glass core through which light propagates. In a multimode fiber, the diameter of the core is 50μm~65μm, which is roughly equivalent to the thickness of a human hair. The diameter of the single-mode fiber core is 8 μm to 10 μm. The core is surrounded by a glass envelope with a lower refractive index than the core to keep the optical fiber in the core. On the outside is a thin plastic jacket to protect the envelope.

2.Classification

Optical fiber jumpers can be divided into common silicon-based

Optical fiber patch cord common head

Optical fiber patch cord common head

Optical fiber single-mode and multi-mode patch cords, as well as other optical fiber patch cords such as plastics as the transmission medium; according to the structure of the connector, it can be divided into: FC patch cords, SC patch cords, ST patch cords, LC patch cords, MTRJ jumper, MPO jumper, MU jumper, SMA jumper, FDDI jumper, E2000 jumper, DIN4 jumper, D4 jumper, etc. in various forms. The more common fiber optic jumpers can also be divided into FC-FC, FC-SC, FC-LC, FC-ST, SC-SC, SC-ST, etc.

Single-mode Fiber (Single-mode Fiber): Generally, fiber jumpers are indicated by yellow, and the connectors and protective sleeves are blue; the transmission distance is longer.

Multi-mode fiber (Multi-mode Fiber): general fiber jumpers are represented in orange, and some are represented in gray, and the connectors and protective covers are in beige or black; the transmission distance is short
