FEC TX

FEC TX

Press TEST, OTUk, and FEC (under OTUk TX).

Configuration

Enable FEC allows detecting, reporting and correcting up to 8 symbol
errors (Correctable) per codeword. Over 8 symbol errors, they are
detected and reported as uncorrectable errors. This setting is enabled by
default.

Note: Enable FEC must be selected when Enable Scrambler is not selected in

order to prevent potential alarms caused by a lack of transition on the
optical signal. To disable FEC, first select Enable Scrambler then clear
Enable FEC. See OTU TX
on page 157 for more information on Enable
Scrambler
.

Error Injection

Allows manual or automated error injection.

Note: Error injection is only available when the Enable FEC check box is selected.
