Note: The following signal configuration parameters are available from the
interface block.

and on the Signal tab.

Note: At least one of the two check boxes, FEC or Scrambler, must be selected in
order to prevent potential alarms caused by a lack of bit transition on the
optical signal. For example to disable FEC, first select the Scrambler check
box then clear the FEC check box.
FEC check box, when selected (default), enables the FEC in TX/RX
and allows to detect, report, and correct up to 8 symbol errors
(Correctable) per codeword. If there are over 8 symbol errors
detected, they are reported as uncorrectable errors.
Scrambler check box, when selected (default), provides enough
“0” and “1” transitions on the optical signal for clock recovery.
