Physical Interface
Interface/Rate allows the selection of the loopback tool interface rate:
10/100/1000M Electrical (default), 100M Optical, 1GE Optical, or
10GE LAN.
Connector displays the unused module’s port (on the same
transceiver system when applicable) for the selected interface/rate.
Ethernet 10/100/1000M electrical is supported on optical connector
when using an active copper SFP.
Clock Mode: Displays the clock mode
Internal: Internal clock of the unit (STRATUM 3).
Recovered: Line clock from the input port signal involved in the tool.
Wa ve le ng th (nm) indicates, when supported, the detected
wavelength.
Modify button, available with tunable transceivers when the
TunableOptics
software option is enabled, is used to configure the
transceiver wavelength.
Wavelength (nm) indicates the actual wavelength value selected.
Use the scroll box and/or the -/+ buttons to select the wavelength.
The minimum and maximum wavelength values are displayed.
Channel Number indicates the actual ITU channel number based
on ITU Grid.
Frequency (THz) indicates the actual Frequency based on ITU Grid
Channel Spacing (GHz) indicates the difference in frequency
between two adjacent channel detected from the transceiver
device.
Restore Previous restores the current value present in the
transceiver device.
