QSFP+ cables and SFP+ cables for short distance

The QSFP+ cables and SFP+ cables are suitable for the short transmission distance. At present, the fiber and copper caber transmission standard of 10G Ethernet have been launched. However, there is only the fiber standard without copper standard for the 40G Ethernet transmission now.

 

 

From the perspective of the development of wiring, generally, the standard of copper cable is always behind the fiber standard and the application standard. Currently, the TIA and ISO have already established a working group to carry out the research work of the copper standard.

 

 

 

 

Actually, the QSFP+ cable is a choice for short transmission distance. Generally, QSFP+ cables are used to connect the ToR switches. 

 

 

QSFP+ cables and SFP+ cables are both suitable for the short transmission distance. The fiber can be considered for the long transmission distance. The standard distance of OM3 multi-mode fiber is 100m and the OM4 is 150m. The single-mode fiber will not encounter the problem of transmission distance.

 

 

 

 

For the high-density, high-performance, longer distance and high-speed and other requirements, the MPO/MTP will be a more reasonable choice.
