In data center cabling, how to match the corresponding types of optical fiber jumpers for different types of optical modules? The editor will sort out the knowledge through this article, and I believe it can provide corresponding help to everyone.

There are many types of optical modules that can be classified according to package classification (SFP,SFP+,XFP,XENPAK, X2, SFP28, QSFP+, QSFP28, CFP2, etc.), by transmission distance, by wavelength, by rate, and then with easy Sky Optical Communications (etulink.com) to see how to match the corresponding fiber jumper types for 10G SFP+ optical modules.

Types of optical fiber jumpers

When judging the type of optical fiber jumper, the interface type is one of the essential factors. We know that optical fiber interface is a physical interface used to connect optical fiber cables, which usually has several types, such as SC, LC, FC, ST, MPO/MTP and so on. Different optical modules have different optical fiber interfaces. The interfaces of common optical modules usually have two ports (one for receiving optical signals and the other for transmitting optical signals), that is, duplex SC or duplex LC, so duplex SC/LC fiber jumpers are needed. On the other hand, the BiDi single-fiber optical module has only one port (it can not only receive and transmit optical signals), so it needs to use simplex fiber jumper.

The type of optical fiber jumper is not only judged according to the interface type, but also needs to consider the transmission mode of optical fiber jumper. According to the different transmission mode, optical fiber jumper can be divided into single-mode optical fiber jumper and multimode optical fiber jumper. The single-mode fiber jumper uses glass with a diameter of 9x125 fiber, while the multimode fiber jumper uses glass with a diameter of OM1 62.5amp 125fiber or OM2 50amp 125fiber. In addition, there are 10G OM3 and OM4 multimode fiber jumper types. Different jumpers are suitable for different usage scenarios. Single-mode optical fiber jumpers support long-distance transmission, while multimode optical fiber jumpers are generally used for short-distance links.

10g SFP+ Optical Module with corresponding Optical Fiber jumper Typ

A 10G optical module is an optical module that can send and receive 10.3GbpsG data signals every second. According to the different packaging, 10G optical module can be divided into XENPAK optical module, X2 optical module, XFP optical module and SFP+ optical module. At present, 10G SFP+ optical module is popular, which is very popular because of its strong compatibility, small size, low cost, low power consumption and other factors.

The following table mainly describes the types of optical fiber jumpers used for 10G SFP+ optical modules.

A user asked: can the type of single-mode fiber jumper be plugged into the multimode optical module?

Answer: first of all, the divergence angle of the optical signal emitted by the multimode optical module is large, the jumper aperture of the single-mode fiber is small, and there is too little light running into the fiber to transmit over a long distance, while the jumper of the single-mode fiber is very long, and the light may be attenuated before it reaches the end point, so it is impossible to connect the link in this way. On the other hand, docking is not recommended for optical modules with different transmission distances, because the interface indexes of optical modules with different transmission distances are quite different, and if only short-distance transmission is needed, optical modules with long-distance transmission do not need to be equipped with long-distance optical modules. after all, the optical module with long transmission distance is more expensive.
