                          ST optic fiber patch cord  

 

Definition

 

     Fiber optic patch cord refers to the optical fiber that can be connected to desktop computer or device directly, convenient for device’s connectivity and management. The patch cord is used from device to fiber optic cabling connection. It has thick layer of protection, and is usually used in the connection between the optical and the terminal box.

 

 

Structure

 

     Fiber optic patch cord is similar to coaxial cable, only without mesh shield. Its center is core of glass for light propagation. The diameter of core is 15μm~50μm in multi-mode optical fiber, equal to the thickness of human hair. But the diameter of single-mode optical fiber core is 8μm~10μm. The core surrounded by a layer of lower refractive index than the core of the glass envelope keep the optical fiber in the core. And then the outside is a thin layer of plastic jacket to protect the envelope.

 

 

 

Classification

 

      According to different transmission media, fiber optic patch cord can be divided to common silicon-based optical fiber, Single-mode and Multi-mode patch cord, and other fiber optic patch cord that transmit through media such as plastic.

 

     According to connector structure styles, it can be divided to patch cord of FC, SC, ST, LC, MTRJ, MU, E2000, DIN4, etc.

 

    Single-mode fiber: Cable Color is yellow. The connector and protective sleeve are blue. Its transmission distance is longer

 

     Multi-mode fiber: Cable color is orange or grey. The connector and protective sleeve are beige or black. Its transmission distance is shorter

 

     According to Outer protection layer materials, it can be divided to PVC and LSZH

Notices

Don’t bend and circle the fiber optic patch cord excessively; this will increase the attenuation of light transmission.The optical module transceiver wavelength of both ends of fiber optic patch cord must be consistent, which means it should be the same wavelength of optical module at the two ends of it.Must use the protective cover to protect the connectors, to avoid that dust and oil would damage the optical fiber coupling.
