4.3.1.4 SFP Module Information
The WGSW-48040HP has supported the SFP module with digital diagnostics monitoring (DDM) function. This feature is also
known as digital optical monitoring (DOM). You can check the physical or operational status of an SFP module via the SFP
Module Information page. This page shows the operational status, such as the transceiver type, speed, wavelength, optical
output power, optical input power, temperature, laser bias current and transceiver supply voltage in real time. You can also use
the hyperlink of port no. to check the statistics on a specific interface. The SFP Module Information screen in
appears.
