Tuning XFPs The ITU-T G.694.2 standard provides a frequency grid for
DWDM which creates channel spacing from 12.5 GHz to
100 GHz. The channel spacing allows different carriers to run
on the same fiber. Using a tunable XFP in our instrument, you
can use different channels or wavelengths. Most XFPs are
designed for C-band wavelengths.
To tune a XFP
1 Verify whether your XFP supports tuning by viewing the
Connector Setup.
This screen varies depending on the XFP device.
Notice the first two lines. The first line indicates that the
XFP is tunable, and may show which wavelengths are
tunable. The second line indicates which types of tuning
are supported.
