=== {{nowrap|25 Gbit/s}} SFP28 ===
SFP28 is a {{nowrap|25 Gbit/s}} interface which evolved from the [[100 Gigabit Ethernet]] interface which is typically implemented with 4 by {{nowrap|25 Gbit/s}} data lanes. Identical in mechanical dimensions to SFP and SFP+, SFP28 implements one {{nowrap|28 Gbit/s}} lane<ref>{{Cite web|url=http://www.ethernetsummit.com/English/Collaterals/Proceedings/2015/20150414_H13_Neer.pdf|title=Ethernet Summit SFP28 examples}}</ref> accommodating {{nowrap|25 Gbit/s}} of data with encoding overhead.<ref>{{Cite web|url=http://www.cisco.com/c/en/us/products/collateral/interfaces-modules/transceiver-modules/datasheet-c78-736950.html|title=Cisco SFP28 product examples}}</ref>
