FTLF8524P3NL Pluggable SFP Product Specification – November 2011 VIII. Digital Diagnostic Functions Finisar FTLF8524P3BNL SFP transceivers support the 2-wire serial communication protocol as defined in the SFP MSA1. It is very closely related to the E2PROM defined in the GBIC standard, with the same electrical specifications. The standard SFP serial ID provides access to identification information that describes the transceiver’s capabilities, standard interfaces, manufacturer, and other information.
