Cisco Transceiver Modules support Ethernet, Sonet/SDH and Fibre Channel applications across all Cisco switching and routing platforms.
CablesAndKits provides two options when purchasing SFP, GBIC, and other Transceivers.
Cisco Original (Cisco Label) - These transceivers are manufactured by Cisco.
Cisco Compatible (3rd party compatible transceivers) - Transceivers manufactured by companies other than Cisco. OEM transceivers are exactly the same as Cisco Original Transceivers but offer a longer warranty and are a more economical solution.
