ABSTRACT:
A method and system for setting a variable forward error correction overhead in an optical transport network frame for an optical link at a node are disclosed. In one embodiment, a method includes selecting a forward error correction overhead, signaling an optical node the selected forward error correction overhead, and setting the forward error correction overhead in the optical network transport frame for use in transmission of data over the optical link. In one embodiment, the forward error correction overhead is complementary to the data payload to maintain total transmission rate.
