Fibre Channel long-distance technology
This section describes the following Fibre Channel long-distance methodology and hardware for a
SAN extension:
• Fiber optic transceivers , page 282
• Wavelength division multiplexing , page 283
• Extended fabric settings for Fibre Channel switches , page 287
Fiber optic transceivers
Fibre Channel switches use one of the following types of fiber optic transceivers. The transceivers can
be short wave or long wave. Use long-wave transceivers for SAN extension.
• The 8 Gb/s, 4 Gb/s and 2 Gb/s transceivers are known as SFPs and use LC style connectors
(
Figure 77 ).

• The 1 Gb/s transceivers can be LC SFPs ( Figure 77 ) or GBICs, which use SC style connectors
( Figure 78 ).
