(canceled)

A receiver for an optical network, the receiver comprising interface circuitry and processing circuity configured to:

• receive a data burst comprising a preamble, the preamble comprising a first subsection comprising a repetitive signal pattern, and a second subsection of the preamble subsequent to the first subsection, the second subsection comprising a predetermined signal sequence;
• and
• determine information for an error correction code or information for a non-linear equalizer using the predetermined signal sequence of the preamble.
