What is the difference between SFP+ and SFP

The difference between SFP+ and SFP. The pinout of SFP and SFP+ connectors are identical. However, SFP is data rate of 6Gb/s, whereas SFP+ is designed for 10Gb/s.

 

The SFP receptacles and plugs are not as well impedance matched as SFP+ receptacles and plugs.

 

Also SFP+ cable is designed for 10Gb/s whereas SFP cable may not be able to satisfactorily transmit that rate.

XFP Module

10G small hot-pluggable XFP module is different from the XENPAK architecture and its 4-channel interface. XFP module adopts full-speed single serial module of a XFI (10Gb serial interface) to replace the XENPAK and its derived products. Since the XFP module doesn't have serializer/ deserializer, XFP is smaller, cheaper than XENPAK. And its’ power consumption is also less than XENPAK. 

SFP+ Module

SFP+ module is smaller than XFP module. It transferred the circuit, which is used for the clock and data recovery, from the chip to the card.  With its miniaturization, low cost and other advantages, SFP+ meets the high-density demand of device. From 2002 to 2010, SFP+ has replaced XFP to be the mainstream of 10G market. 

QSFP+ Module

Quad Small Form-factor Pluggable, the QSFP+ has 4-channel SFP+ interfaces. QSFP+ is designed as the high-speed pluggable solution to meet higher-density of market. As a fiber optical solution, the speed and density are both better than the 4-channel CX4 interface.  Since QSFP+ can support 4 channels’ data transmission at 10Gbps per channel with the same port size of XFP, the density of QSFP+ ups to 4 times of XFP products.
