Chapter 4 Basic Testing
Preparing to test
Verifying supported line rates
Before testing, verify that the optic can support the line rate for the circuit that you are
testing.
1
Press the Setup soft key.
2
Select Interface, then view the Connector tab.
The recommended rates are listed. Press the Results soft key to return to the results
screen.
If the line rate is not supported by the transceiver, "Recommended optic rates not avail-
able" appears. Turn the instrument off and try another transceiver.
Tuning SFP+ and XFP transceivers
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 SFP+ or XFP in our instrument, you
can use different channels or wavelengths. Most XFPs are designed for C-band wave-
lengths.
