[1] Optical Fiber Patch Cord/Cable is similar to coaxial cable, except that there is no mesh shielding layer. At the center is a glass core that transmits light. In multimode fiber, the core diameter is 50 μ m~65 μ m. It is roughly equivalent to the thickness of human hair. The diameter of single-mode fiber core is 8 μ m~10 μ m。 The core is surrounded by a glass envelope with a refractive index lower than that of the core to keep the fiber in the core. The outer layer is a thin plastic jacket to protect the envelope.

Common head of optical fiber jumper

Optical fiber jumpers are commonly used for single-mode and multi-mode jumpers of head optical fiber, as well as other optical fiber jumpers using plastic as the transmission medium; According to the connector structure, it can be divided into FC jumper, SC jumper, ST jumper, LC jumper, MTRJ jumper, MPO jumper, MU jumper, SMA jumper, FDDI jumper, E2000 jumper, DIN4 jumper, D4 jumper, etc. Common optical fiber jumpers can also be divided into FC-FC, FC-SC, FC-LC, FC-ST, SC-SC, SC-ST, etc.

Single mode fiber: Generally, the optical fiber jumper is yellow, and the connector and protective sleeve are blue; Long transmission distance.

Multi mode fiber: generally, optical fiber jumpers are indicated in orange or gray, and connectors and protective sleeves are beige or black; Short transmission distance

3 Note that the optical modules at both ends of the edited optical fiber jumper must have the same receiving and transmitting wavelengths, that is, the optical modules at both ends of the optical fiber must have the same wavelength. The simple way to distinguish the optical modules is to have the same color. Generally, the short wave optical module uses multimode optical fiber (orange optical fiber) and the long wave optical module uses single-mode optical fiber (yellow optical fiber) to ensure the accuracy of data transmission.
