In the data center cabling, optical fiber jumpers if no data communication module can not be transmitted, the transmission medium due to the different optical modules, optical interfaces, data rate and transmission distance are different, then, SFP optical module with is how to choose corresponding fiber jumpers do?
The optical module according to the package classification can be divided into SFP, SFP +, XFP, XENPAK, X2, SFP28, QSFP +, QSFP28, CFP2 the like, wherein the SFP package of the optical module according to the transmission medium points, light copper-based electrical module and an optical fiber module, so the choice to optical fiber jumper first consider the problem of the interface module, the optical module is usually a receiving port and a sending port, or using an LC duplex SC connector, so with the duplex fiber jumpers. But for BiDi single fiber optical module, one port can handle two transmission and receiving function, BiDi single fiber transceiver module used with simplex jumper.
The second is the type of fiber, single-mode fiber and multimode jumper, the jumper can be divided into single-mode OS1 and OS2, the multimode fiber jumpers can be divided into OM1, OM2, OM3, OM4. Different jumpers are suitable for different usage scenarios. Jumper support single-mode fiber for long distance transmission, is connected to the single-mode optical module; and multi-mode fiber generally used for short-distance link jumpers, usually connected to the multi-mode optical module.
