Field Description
Vendor Name The vendor name is a 16 character field that contains ASCII charac-
ters, left-aligned and padded on the right with ASCII spaces (20h). The
vendor name shall be the full name of the corporation, a commonly
accepted abbreviation of the name of the corporation, the SCSI com-
pany code for the corporation, or the stock exchange code for the cor-
poration.
Length (50um, OM2) This value specifies link length that is supported by the transceiver
while operating in compliance with applicable standards using 50
micron multimode OM2 [500MHz*km at 850nm] fiber. A value of zero
means that the transceiver does not support 50 micron multimode fiber
or that the length information must be determined from the transceiver
technology.
Length (62.5um, OM1) This value specifies link length that is supported by the transceiver
while operating in compliance with applicable standards using 62.5
micron multimode OM1 [200 MHz*km at 850nm, 500 MHz*km at
1310nm] fiber. A value of zero means that the transceiver does not
support 62.5 micron multimode fiber or that the length information must
determined from the transceiver technology
Vendor SN The vendor serial number (vendor SN) is a 16 character field that con-
tains ASCII characters, left-aligned and padded on the right with ASCII
spaces (20h), defining the vendor's serial number for the transceiver. A
value of all zero in the 16-byte field indicates that the vendor SN is
unspecified.
Vendor PN The vendor part number (vendor PN) is a 16-byte field that contains
ASCII characters, left aligned and added 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.
