Company Identifier for the vendor. A value of all zero in the 3-byte field indicates that the Vendor OUI
is unspecified.
Vendor PN
The vendor part number (vendor PN) is a 16-byte field that contains ASCII characters, left-aligned and
padded on the right with ASCII spaces (20h), defining the vendor part number or product name. A
value of all zero in the 16-byte field indicates that the vendor PN is unspecified.
Vendor Rev
The vendor revision number (vendor rev) is a 4-byte field that contains ASCII characters, left-aligned
and padded on the right with ASCII spaces (20h), defining the vendor’s product revision number. A
value of all zero in the 4-byte field indicates that the vendor Rev is unspecified.
CC_BASE
The check code is a one byte code that can be used to verify that the first 64 bytes of serial
information in the SFP transceiver is valid. The check code shall be the low order 8 bits of the sum of
the contents of all the bytes from byte 0 to byte 62, inclusive.
Options
The bits in the option field shall specify the options implemented in the SFP transceiver.

Description
BR, max
The upper bit rate limit at which the SFP transceiver will still meet its specifications (BR, max) is
specified in units of 1% above the nominal bit rate. A value of zero indicates that this field is not
specified.
BR, min
The lower bit rate limit at which the SFP transceiver will still meet its specifications (BR, min) is
specified in units of 1% below the nominal bit rate. A value of zero indicates that this field is not
specified.
Vendor SN
The vendor serial number (vendor SN) is a 16 character field that contains ASCII characters, left-
