Transceiver

1

The following bit significant indicators define the electronic

or optical interfaces that are

2

supported by the transceiver. At least one bit shall be set in this field. For Fibre Channel

3

transceivers, the Fibre Channel speed, transmission media, transmitter technology, and

4

distance capability shall all be indicated. The SONET Compliance Codes are described

5

in more detail in table 3.4a.
