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 *5μm~*0μm in
multi-mode optical fiber, equal to the thickness of human hair. But
the diameter of single-mode optical fiber core is 8μm~*0μm.
The core surrounded by a layer of
lower refractive index than the core of the glass envelope
keepthe 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, E***0, 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
