This appendix provides information about the small form-factor pluggable (SFP)
module and cabling used with the 1783-EMS08T switch.
Available SFP Modules
Available SFP modules include the following:
• 1783-SFP1GSX - 1000BASE-SX multi-mode fiber transceiver
• 1783-SFP1GLX - 1000BASE-LX single-mode fiber transceiver
SFP Module Cable
Specifications
The following table lists the cable specifications for the fiber-optic SFP module
connections.
Each port must match the wave-length specifications on the other end of the
cable. For reliable communication, the cable must not exceed the rated maximum
cable length.
TIP
For detailed instructions on installing, removing, and connecting the
SFP modules, see the documentation that shipped with the SFP
module.
