ST/ST single-mode fiber jumpers
Fiber jumper wire and coaxial cable similar, but no mesh shield. The center is light propagation glass core. In the multimode optical fiber, core diameter is 15 μ m ~ 50 μ m, roughly and human hair weight quite. And single-mode fiber core diameter to 8 μ m ~ 10 μ m. Outside the core surrounded by a layer of refractive index than core low glass envelope, in order to make optical fiber to remain in within the core. To the outside is a layer of thin plastic coat to protect the seal fiber jumper wire classification
Fiber optic jumper according to the transmission medium can be divided into common silicon base fiber single-mode and multimode jump line, and other such as plastic as transmission medium optical fiber jumper wire; According to the joint structure forms can be divided into: FC jump line, SC, ST jump jump line line, LC jump line, MTRJ jump line, MPO jump line, MU jump line, SMA jump line, FDDI jump line and E2000 jump line, DIN4 jump line, D4 jumper wire and so on various forms. More common optical fiber jumper wire can also be divided into FC - FC, SC, FC - FC - LC, FC - ST, SC - SC, SC, ST, etc. Single-mode Fiber (Single - mode Fiber) : general optical Fiber jumpers in yellow said, joint and protective sleeve for blue; Transmission distance is long.
Multimode Fiber (Multi - mode Fiber) : general optical Fiber jumper with orange said, also some USES grey said, joint and protection applying cream-colored or black; Transmission distance is short.
Fiber use notice
Fiber optic jumpers both ends of the optical module transceiver wavelength must agree, that is to say the fiber ends must be the same wavelength of light module, a simple method is to distinguish the color of light module should agree. The general circumstances, short wave optical module USES multimode optical fiber (orange fiber), long wave optical module using single-mode fiber (yellow fiber), to ensure the accuracy of the data transmission.
Optical fiber in use do not excessive bending and around the ring, this can increase the light in the transmission process of attenuation.
Fiber optic jumper wire after use must use protective sleeve will fiber joint protection up, dust and oil pollution can damage fiber coupling.
If the optical fiber joint get dirty words, can dip in with cotton alcohol cleaning, otherwise, it will influence the quality of communication. Fiber optic jumper wire characteristics
1. Low insertion loss
2. Good repeatability
3. Echo loss is big
4. Mutual plug performance is good
5. Temperature stability is good
Fiber optic jumper wire application:
