Fiber Optic Patch Cord

Fiber Optic 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
