Description: MIB for managing Erbium-Doped Fiber Amplifier (EDFA) card configuration, pump status, optical power, and VOA settings on Smartoptics SiteLight platforms

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is SL-EDFA-MIB?

SL-EDFA-MIB is a vendor MIB from Smartoptics covering Erbium-Doped Fiber Amplifier (EDFA) line cards in its SiteLight optical transport platform, which boost optical signal power in DWDM networks. It exposes configuration objects for amplifier control mode and Variable Optical Attenuator (VOA) settings alongside real-time operational data for each amplifier card. Its core purpose is hardware status monitoring of the optical amplifier: edfaPumpTemp tracks the laser pump's temperature, edfaRxPower reports received optical power, and edfaPumpAdminStatus/edfaPumpOperStatus together with edfaStatus reveal whether the pump laser and overall card are administratively enabled and actually operating correctly. Traps defined under edfaTraps/edfaTraps0 signal fault conditions such as pump failure directly to a management system, and the module fits alongside related SiteLight MIBs (e.g., SL-DCM-MIB, SL-EVENT-MIB) sharing the platform's indexing scheme. It is deployed in DWDM optical transport nodes on long-haul or metro fiber links where EDFA cards amplify multiplexed wavelengths, making SL-EDFA-MIB SNMP monitoring essential for catching pump failures before they affect the optical link.

IPNetwork Monitor allows you to monitor SNMP objects defined in SL-EDFA-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Smartoptics SiteLight optical transport platform (EDFA card)

Monitoring Examples

An operator polls edfaConfigTable/edfaConfigEntry indexed by edfaIfIndex to check each amplifier card's edfaPumpTemp for overheating and edfaRxPower to confirm incoming optical power is within expected bounds. Comparing edfaPumpAdminStatus against edfaPumpOperStatus reveals a pump laser that has been enabled administratively but has actually failed to come up, while edfaStatus gives an overall card health summary. edfaVoa and edfaAutomaticMode/edfaAdminControlMode/edfaOperControlMode show whether the amplifier's attenuation is being managed automatically or manually, and a subscription to edfaTraps0 would alert the NOC immediately if a pump failure occurs.

What Can Be Monitored

pump laser temperature
received optical power (Rx)
pump admin/operational status
overall EDFA card status
VOA attenuation setting
control mode (auto/manual, admin/oper)

How to Use in IPNetwork Monitor

Example using edfaPumpTemp OID:

Select a Smartoptics SiteLight optical transport platform, EDFA card (pump temperature/power/status) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type edfaPumpTemp into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The pump temperture (in Kelvin). On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the reported value exceeds the level expected for healthy operation, since sustained high temperature often precedes thermal shutdown or hardware degradation. Click Finish to create the monitor; you can adjust any parameter later.
