Optical fiber jumper refers to the optical fiber directly connected to the desktop computer or device to facilitate the connection and management of the device. Used to make jumpers from equipment to fiber optic cabling links. There is a thicker protective layer, which is generally used for the connection between the optical transceiver and the terminal box.
Fiber optic jumpers are similar to coaxial cables, except that there is no mesh shield. In the center is the glass core through which light propagates. In a multimode fiber, the core diameter is 15μm-50μm, roughly equivalent to the thickness of a human hair. The single-mode fiber core has a diameter of 8 μm to 10 μm. The core is surrounded by a glass envelope with a lower refractive index than the core to keep the fiber in the core. On the outside is a thin plastic jacket to protect the envelope.
Fiber patch cord classification
Optical fiber jumpers can be divided into common silicon-based optical fiber single-mode and multi-mode jumpers according to different transmission media, and other optical fiber jumpers such as plastics as transmission media;
According to the structure of the connector, it can be divided into: FC jumper, SC jumper, ST jumper, LC jumper, MTRJ jumper, MU jumper, E2000 jumper, DIN4 jumper, and so on.
Single-mode fiber (Single-mode Fiber): Generally, fiber jumpers are indicated by yellow, and the connectors and protective sleeves are blue; the transmission distance is longer.
Multi-mode fiber (Multi-mode Fiber): generally divided into Gigabit multimode and 10 Gigabit multimode, 10 Gigabit multimode is divided into 10 Gigabit 150, Gigabit 300, Gigabit 550, Gigabit fiber patch cords are indicated by orange, ten thousand Mega-multimode fiber is represented by lake blue and grass green, and some are shown in red. The transmission distance of multimode fiber is shorter.
