1Identifier

2The identifier value specifies the physical device described by the serial information.

3This value shall be included in the serial data. The defined identifier values are shown in

4table 3.2. Finisar SFP modules have this byte set to 03h. Finisar GBIC modules have

5this byte set to 01h.

10Extended Identifier

11The extended identifier value provides additional information about the transceiver.

12The field is set to 04h for all non-custom SFP and GBIC modules indicating serial ID

13module definition.

15Connector

16The connector value indicates the external connector provided on the interface. This

17value shall be included in the serial data. The defined connector values are shown in

18 table 3.3. Note that 01h – 05h are not SFP compatible, and are included for

19compatibility with GBIC standards. Finisar optical SFP modules currently have this byte

20set to 07h (optical LC connector). GBIC modules have the byte set to 01h (SC).
