Many people do not know SFP and sfp+ difference, so sometimes unnecessary trouble. The 10G module has experienced from the 300Pin, XENPAK, X2, XFP development, finally achieve the same size and SFP transmission of 10G signal, this is SFP+. SFP+ optical transceiver is the SFP (sometimes called mini-GBIC ) upgrade. In a Gigabit Ethernet and 1G, 2G, 4G fiber channel on SFP has been widely applied. SFP+ in order to adapt to the higher data rate, design than SFP enhanced electromagnetic shielding and signal protection characteristics, and to develop new electrical interface specification.
The SFP package – Hot Swap small package module, the highest rate of up to 10G, using LC interface. SFP ( Small Form Pluggable ), can be simply understood as the upgrade version of GBIC. SFP module volume ratio of GBIC module can be reduced by half, in the same panel configuration of many more than doubled the number of ports. The sfp module to other basic functions and GBIC agreement. Some switches manufacturer called SFP module for small GBIC ( MINI-GBIC ). SFP Module It is a popular industry format jointly developed and supported by many network component vendors.SFP Module are designed to support SONET, Gigabit Ethernet, Fibre Channel, and other communications standards. Due to its smaller size, SFP obsoletes the formerly ubiquitous gigabit interface converter (GBIC); the SFP is sometimes referred to as a Mini-GBIC although no device with this name has ever been defined in the MSAs.
The enhanced small form-factor pluggable (SFP+) is an enhanced version of the SFP that supports data rates up to 10 Gbit/s. SFP+ (Small Form-Factor Pluggable Plus) is an innovative, next-generation optical transceiver. Initially, it is targeted to support speeds of 10 Gbps for next-generation Gigabit Ethernet applications. It is smaller than any of the currently shipping form factors and provides the highest density per line card.
SFP+ Transceiver is interchangeable with SFP transceiver and can be used in the same cages as SFP transceiver. For 10G applications, SFP+ Transceiver has a smaller footprint and lower power consumption than XFP transceiver, and it is low power consumption. The electrical interface to the host board for SFP transceiver and SFP+ transceiver is the same serial.
Sopto manufactures complete range of compatible SFP+ transceivers, such us SFP+ MM 300m, SFP+ 10km, SFP+ 40km, SFP+ 80km, CWDM SFP+, DWDM SFP+, BiDi SFP+, and compatible cisco sfp+(including the sfp-10g-sr cisco, SFP-10G-LR(LRM), SFP-10G-ER, SFP-10G-ZR.), hp sfp+, juniper sfp+ and so on .
The difference between SFP and SFP+:
