What is patch cord

Fiber patch cord refers to the desktop computer or device directly connected to the fiber, aiming to facilitate device connectivity and management. Used the jumper cables from the device to the optical fiber cabling link. Thicker layer of protection, generally used in the connection between the Optical and the terminal box.

Fiber patch cord

Fiber jumper and coaxial cable, just do not mesh shield. The center is the core of light propagation in glass. Multimode fiber core diameter of 15μm ~ 50μm, broadly in line with the thickness of a human hair. Single-mode fiber core diameter of 8μm ~ 10μm. Outside the core surrounded by a layer of lower refractive index than the core of the glass envelope, so that the fiber remained at the core. And then the outside is a thin plastic coat used to protect the envelope.

Fiber patch cord Category According to the different transmission media,the fiber patch cord can be divided into common silicon-based optical fiber single-mode, multimode fiber patch cord, as well as other fiber jumpers such as plastic, such as the transmission medium. connector structure can be divided into: FC , SC , ST , LC , MTRJ , MPO, MU , SMA , FDDI, , E2000 , DIN4,D4 and so on. The more common fiber jumper can also be divided into the FC-FC, ​​FC-SC, FC-LC, FC-ST, SC-SC, the SC-ST.

Single-mode fiber : Fiber Jumper with yellow connector and protective sleeve blue, longer transmission distance.

Multimode fiber : The general fiber optical patch cord use orange and some gray fittings and

protection apply beige or black,and the transmission distance is short.
