The IEEE 802.3ae committee ratified the 10 Gigabit Ethernet standard and along with the general specification, defined a number of fiber optic interfaces. These standard interfaces attempted to satisfy a number of different objectives including support for MMF and SMF compatibility.
SR SFP+
•10GBASE-SR transceivers are used in a data center to interconnect two Ethernet switches or to link an end-device (e.g. 10 Gigabit Ethernet servers or NAS device) to an Ethernet switch
LR SFP+
•10GBASE-LR transceivers are most commonly deployed in inter- building single mode connections
ER SFP+
•10GBASE-ER transceivers are most commonly deployed in between sites or locations of 40 kilometers
ZR SFP+
•10GBASE-ZR transceivers are most commonly deployed in between sites or locations of 80 kilometers
COPPER-CU SFP+
•10GBASE-Copper cables are most commonly deployed in data centers between two devices in the same rack (server to switch or switch to switch)

The SFP+ pluggable interface is an industry standard—Multisource
Agreement (MSA) for pluggable 10 Gigabit Ethernet Optics.
