SFP MSA Specification
The Small Form-Factor Pluggable (SFP) MSA (Multi Source Agreement) is a specification for a common 
interface for optical modular transceivers. The SFP connector consists of a 20-pin receptacle and an SFP 
housing cage. The connector provides the interface for the hot pluggable SFP module. Each SFP module 
contains a serial interface to provide identification information that describes the SFP capabilities, stand 
interfaces, manufacturer and other information.
For information on installing SFPs, refer to the documentation included with the transceiver.
