Comparing with other 10G cable such as XFP

10GBASE-T or IEEE 802.3an-2006 is a standard released in 2006 to provide 10 Gigabit/second connections over unshielded or shielded twisted pair cables over distances up to 100m(330ft). The twisted pair cable is typically comprised of four twisted pairs of 23AWG copper cable under the same jacket, but divided into four individual quadrants separated by a plastic spine extended throughout the entire length of the cable.  Some manufacturers of cable are able to achieve the  Network 10G cable with unshielded twisted pairs, while other manufacturers construct their cable with twisted pairs wrapped with a foil shield.  CAT6 cable can be used in a 10G application, but there is a distance limitation of 55M (180ft).  To reach full 100M (330ft) length, CAT6A cable must be used to comply with 10G specifications.  CAT6A or CAT6 “Augmented” is the recommended cable for 10G networking applications.Comparing with other 10G cable such as XFP, X2 and Xenpak, SFP+ transceiver is the smallest 10G form factor.SFP+ module is interchangeable with SFP module and can be used in the Scrat Adaptor same cages as SFP module.SFP plus is an upgraded version of the small form pluggable transceivers.SFP(small form-factor pluggable) is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. The electrical interface to the host board for SFP module and SFP+ module is the same serial.
