The SFP+ module provides two inputs RS0 and RS1 that can optionally be used for rate selection. RS0
controls the receive path signaling rate compatibility, and RS1 controls the transmit path signaling rate
compatibility. The host and module may choose to use either, both, or none of these functions. Because
contact 9 in the classic SFP INF-‐8074i is connected to VeeR, and SFP+ host utilizing RS1 must provide
short circuit protection.
This rate select functionality can also be controlled by software as defined by SFF-‐8472. Optionally the
rate select methods of Part 2 SFF-‐8079 may be used instead of the method described here by setting the
management declaration bit (A0h byte 93 bit 2) to 1, see SFF-‐8472.
