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.

Eye Safety
SFP transceivers are international Class 1 laser products and are eye-safe devices when operated within the
limits of manufacturers’ specifications. Operating SFP transceivers in a manner inconsistent with intended
usage and specification may result in hazardous radiation exposure.
