HOW WELL DO YOU KNOW YOUR SFP+
To meet the need for faster transmission speed, the SFP+ (or SFP10) was introduced in 2006, as an extension of the SFP connector. Based on IEEE802.3ae, SFF-8431, and SFF-8432 protocol specifications.As we know, a SFP module just looks the same as the SFP+ module And as they have the same size, your SFP transceiver will fit seamlessly into an SFP+ switch port and vice versa.Interestingly, today’s most applications, SFP+ module usually supports 8 Gbit/s Fibre channel . The SFP+ modules deliver 5 GbE and 2.5 GbE network connectivity speeds through 100 meters of Cat 5e and Cat 6 cabling. 10 GbE speeds are achieved with cables up to 30 meters. SFP+ products are compliant to Ethernet, SONET, CPRI, and OTN, and other communication standards.However, the primary difference between an SFP and a SFP+ is their transmission speed. It is noticeable that SFP/SFP+ are both copper and optical.
furthermore, If you plug an SFP device into an SFP+ port, the speed will be locked at 1 Gbps. Plugging an SFP+ module into an SFP port delivers no results at all, as the 10G transceiver can never auto-negotiate to 1Gbps.Channel standards supports distances from 220m to 80km distance over multimode fiber for short distance and single mode fiber for long distance.XENPAK, X2, XFP and finally achieve with the same size as SFP which can transmit 10G signals called SFP+. In fact, SFP+ is an enhanced version of the SFP. The SFP+ specifications are based on SFF-8431.
