AN-2030: Digital Diagnostic Monitoring Interface for Optical Transceivers

F i n i s a r

1Transceiver

2The following bit significant indicators define the electronic or optical interfaces that are

3supported by the transceiver. At least one bit shall be set in this field. For Fibre Channel

4transceivers, the Fibre Channel speed, transmission media, transmitter technology, and

5distance capability shall all be indicated. The SONET Compliance Codes are described

6in more detail in table 3.4a.
