4.4.4 SFP Module Information
The WGSD-10020HP 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 Figure 4-4-4
appears.

The page includes the following fields:
Object Description
 Type Display the type of the current SFP module and the possible types are:

10GBase-SR

10GBase-LR

1000BASE-SX

1000Base-LX

100Base-FX
 Speed Display the speed of the current SFP module; the speed value or description is
taken from the SFP module. Different vendors’ SFP modules might show different
speed information.
 Wave Length(nm) Display the wavelength of current SFP module; the wavelength value is obtained
from the SFP module. Use this column to check if the wavelength values of two
nodes match while the fiber connection fails.
 Distance(m) Display the support distance of the current SFP module; the distance value is
obtained from the SFP module.
 Temperature(C)
– SFP DDM Module Only
Display the temperature of the current SFP DDM module; the temperature value
is obtained from the SFP DDM module.
 Voltage(V)
– SFP DDM Module Only
Display the voltage of the current SFP DDM module; the voltage value is
obtained from the SFP DDM module.
 Current(mA)
– SFP DDM Module Only
Display the Ampere of the current SFP DDM module; the Ampere value is
obtained from the SFP DDM module.
