The
Global Signal
screen (fiber ports only) displays the optical level measured by the SFP or XFP transceiver. Page 1 displays
the level measurement in dBm for the optical signal.
Loss of Signal (LOS) and the Saturation level for optical signals are shown graphically including the level measurement in dBm.
Signal (Page 2)
Page 2 displays the Optical module (SFP or XFP) information which includes Vendor name, Part Number and Optical
Wavelength. Tap on the
Decode
button to view additional information on SFP optics.
Signal (Page 3)
The received signal frequency and offset is measured and performed on the optical interface (SFP or XFP).
Current:
Indicates the frequency of the input signal.
Offset:
Indicates the difference between the standard rate and the rate of the input signal.
Min (ppm):
Indicates the difference between the standard rate and the minimum deviation detected in the input signal.
Max (ppm):
Indicates the difference between the standard rate and the maximum deviation detected in the input signal.
