The cost of cable XFP to SFP+ cable upgrades

And they also have the same,they are similar in design  10G modules such as XFP to SFP+ cable, X2 and Xenpak, SFP+ transceiver is the smallest 10G form factor.SFP+ module is interchangeable with SFP module and can be used in the same cages as SFP module.SFP plus is an 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.It means that you can replace the component without shutting down the whole system. XFP to SFP+ cable can be replaced without interrupting the operation of your system. Its usual operation is at optical wavelengths of 850 nm, 1310 nm, or 1550 nm. To be able to install this module in  form factor hot pluggable module designed for 10G network applications including 10Gig Ethernet and fibre channel. XFP transceivers are with dual  single wavelength or dense wavelength division multiplexing techniques
