2The nominal bit rate (BR, nominal) is specified in units of 100 Megabits per second,

3rounded off to the nearest 100 Megabits per second. The bit rate includes those bits

4	necessary to encode and delimit the signal as well as those bits	carrying data
5	information. A value of 0 indicates that the bit rate is not specified	and must be

6determined from the transceiver technology. The actual information transfer rate will

7depend on the encoding of the data, as defined by the encoding value.

10Note that this field is an addition to EEPROM data from the original GBIC definition.

11This value specifies the link length that is supported by the transceiver while operating

12in compliance with the applicable standards using single mode fiber. The value is in

13units of kilometers. A value of 255 means that the transceiver supports a link length

14greater than 254 km. A value of zero means that the transceiver does not support single

15mode fiber or that the length information must be determined from the transceiver

16technology.

19This value specifies the link length that is supported by the transceiver while operating

20in compliance with the applicable standards using single mode fiber. The value is in

21units of 100 meters. A value of 255 means that the transceiver supports a link length

22greater than 25.4 km. A value of zero means that the transceiver does not support

23single mode fiber or that the length information must be determined from the transceiver

24technology.

27This value specifies the link length that is supported by the transceiver while operating

28in compliance with the applicable standards using 50 micron multi-mode fiber. The

29value is in units of 10 meters. A value of 255 means that the transceiver supports a link

30length greater than 2.54 km. A value of zero means that the transceiver does not

31support 50 micron multi-mode fiber or that the length information must be determined

32from the transceiver technology.

35This value specifies the link length that is supported by the transceiver while operating

36in compliance with the applicable standards using 62.5 micron multi-mode fiber. The

37value is in units of 10 meters. A value of 255 means that the transceiver supports a link

38length greater than 2.54 km. A value of zero means that the transceiver does not 62.5

39micron multi-mode fiber or that the length information must determined from the
