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.
