Abstract: A method includes mapping, by an optical transceiver, a received first OTU4 signal to a first FlexO frame without interleaving the first OTU4 signal into an ODUC signal prior to mapping the first OTU4 signal to the first FlexO frame. The method also includes communicating, by the optical transceiver, the first FlexO frame with the mapped first OTU4 signal to a coherent DSP over a first FOIC.

Abstract: Embodiments herein describe re-ordering bit-interleaved data to be byte-interleaved data before transmitting the data on an OTN. For example, a transmitter can receive interleaved bits for different symbols that are part of an error correction code to be transmitted in an optical transport network. The transmitter re-orders the interleaved bits into interleaved bytes where each of the interleaved bytes correspond to one of the different symbols. The interleaved bytes can then be transmitted on the OTN.
