This SFP (Small Form-factor Plug-in) transceiver enables one 1000BASE-LX connection. SFPs have a form factor one-half the size of current industry standards
This SFP transceiver can be used in those 3Com switches and modules which support SFP modules. SFPs can be mixed and matched on a given switch to maximize flexibility.
The S FP's simplicity of design create a new definition of user-friendliness with outstanding mechanical and optical performance Enables one 1000BASE-LX connection Use in conjunction with other 3Com SFPs: 3Com 1000BASE-SX SFP Transceiver (3CSFP91), 3Com 1000BASE-T SFP Transceiver (3CSFP93), or 3Com 1000BASE-LH SFP Transceiver (3CSFP97)
