Abstract: In one embodiment an apparatus, method, and system is described, the embodiment an apparatus, method including receiving a stream of data frames at an input interface, the data frames one of including security frames, or being included in security frames, wherein the security frames include payload data, performing forward error correction on the data frames a forward error correction (FEC) decoder, buffering received data frames at a buffer and blanker engine and building a complete security frame of the received data frames, determining whether or not to suppress taking a consequent action based on a frequency of authentication errors at an authentication engine, wherein the consequent action to be taken or suppressed, when taken, is taken upon payload data of one or more security frames including a data frame upon which an authentication error occurred. Related apparatus, methods and systems are also described.

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.
