Digital Diagnostics Monitoring - Alcatel-Lucent 7750 Configuration Manual

Digital Diagnostics Monitoring

Digital Diagnostics Monitoring
Some Alcatel-Lucent SFPs, XFPs, QSFPs, CFPs and the MSA DWDM transponder have Digital
Diagnostics Monitoring (DDM) capability where the transceiver module maintains information
about its working status in device registers including:
•
•
•
•
•
For the case of QSFP and CFPs, DDM Temperature and Supply voltage is available only at the
Module level (to be shown in
The section called
DDM and DDM Lane information:
The QSFP and CFPs, the number of lanes is indicated by DDM attribute "Number of Lanes: 4".
Subsequently, each lane threshold and measured values are shown per lane.
If a given lane entry is not supported by the given QSFP or CFP specific model, then it will be
shown as "-" in the entry.
A sample QSFP and CFP lane information is provided below:
