Enable Scrambler
provides enough “0” and “1” transitions on the optical
signal for clock recovery. The
Enable Scrambler
check box is selected by
default.
Note:
Enable Scrambler
must be selected when
Enable FEC
is not selected in
order to prevent potential alarms caused by a lack of transition on the
optical signal. To disable
Scrambler
, first select the
Enable FEC
check box
then clear the
Enable Scrambler
check box. See FEC TX
on page 130
for
more information on Enable FEC.
