Digital Optical Monitoring

Digital optical monitoring (DOM) provides a diagnostic monitoring interface for SFP and SFP+ optics. DOM supports monitoring of optical output power, optical input power, temperature, laser bias current, and transceiver voltage.

You can configure your RUCKUS device to monitor optical transceivers in the system, either globally or by specified ports. When DOM is enabled, the system monitors the temperature and signal power levels for the optical transceivers in the specified ports. Console messages and syslog messages are triggered when optical operating conditions fall below or rise above the SFP, SFP28, SFP+, QSFP, QSFP+, and QSFP28 manufacturer-recommended thresholds.

Note: DOM is supported on RUCKUS optics. DOM is supported on all the ICX switches.
Note: DOM is not supported for Link Aggregation Group (LAG) interfaces.

For a list of supported media types, refer to the Ruckus Ethernet Optics data sheet.

Beginning with FastIron release 08.0.95, new RUCKUS optic has been introduced for ICX 7650 and ICX 7550. The new 100G-ER4 (Extended Reach 4 Lanes) or 100G-ER4-Lite optic do not support stacking ports. They support 40km transmission with Forward-Error-Correction (FEC) and 30km transmission without FEC.

Note: The 100G-ER4 optic support uplink ports only.
Note: DOM cannot be enabled for user disabled ports. When DOM is configured globally but a port is disabled by the user, the following appears in the output: "Optical monitoring is in progress, please try later".

The show media ethernet command is used to display information about the media device installed in a port.

The 100G-PAM4 optic supports RUCKUS ICX 7850, ICX 7650 and ICX 7550 with new 100G or 200G or 400G standard. They support uplink ports only. The maximum transmission distance for 100G-DR or 100G-DR1 is 500m. DR1 represents one lane with 100G. The maximum transmission distance for 100G-FR or 100G-FR1 is 2km. The maximum transmission distance for 100G-LR or 100G-LR1 is 10km.
