Over the years of 10 gigabit Ethernet’s existence, there have been numerous different form factors and optics types introduced.The oldest X2 Modules remain very popular as the install base is large,

while the newest SFP+ offer a much smaller form factor and the ability to offer 1G/10G combo ports on hardware for the first time.

Like the move from GBIC to SFP the move from X2  to SFP+ seems inevitable, but currently there are four standard modules|form-factors available.

This is a guide to these module types and optical standards currently available.

X2-SFP10G-CVR converts a 10 Gigabit Ethernet X2 port into a 10

Gigabit Ethernet SFP+ port. With the 10G X2-SFP+ Converter, customers have the

flexibility to use the 10 Gigabit X2 interface port of a switch with X2 module or

SFP+ transceivers without having to upgrade or replace the switches. This 10G

X2-SFP+ Adapter help customers protect the investment and this flexibility is critical

when the specific type of interface is not available in one or the other form factor or when

customers want to use the same form factor for interfaces across multiple platforms deployed

in their network. With this 10G X2-SFP+ Adapter, customer can plugged into the

following SFP+ transceivers: SFP+ SR, SFP+ LR, SFP+ ER, SFP+ ZR, CWDM SFP+, DWDM

SFP+, BIDI SFP+.
