B.1 SFP Connector Pinouts
Each of the SFP host or expansion ports is comprised of a case
bottom, an EMI case, and a 20-pin host connector. These port
sockets receive Small-Form-Factor (SFP) fiber optical and copper-
based transceivers. Please refer to the latest Interoperability Test
Report for compatible modules that have been tested to comply with
the sockets. The pinouts are shown in
Figure C-1
and their
definitions are shown in
