AN-2030: Digital Diagnostic Monitoring Interface for Optical Transceivers F i n i s a r
9/26/02 Revision D Page 7
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. 6
