Abstract
An apparatus for marking errors in FlexO/ZR data includes circuitry configured to receive an Open Forward Error Correction (OFEC) block, decode a plurality of checksums in a payload area of the OFEC block, detect errors in the payload area based on the decoded plurality of checksums, and mark the detected errors in the payload area. The plurality of checksums are added during adaptation of the FlexO/ZR data to the OFEC block.
Claims20
An apparatus for marking errors in FlexO/ZR data, the apparatus comprising circuitry configured to:
- receive an Open Forward Error Correction (OFEC) block,
- decode a plurality of checksums in a payload area of the OFEC block,
- detect errors in the payload area based on the decoded plurality of checksums, and
- mark the detected errors in the payload area.
A method for marking errors in FlexO/ZR data, the methods comprising steps of:
- receiving an Open Forward Error Correction (OFEC) block;
- decoding a plurality of checksums in a payload area of the OFEC block;
- detecting errors in the payload area based on the decoded plurality of checksums;
- and
- marking the detected errors in the payload area.
A FlexO/ZR interface comprising:
- circuitry configured to adapt the FlexO/ZR to a first Open Forward Error Correction (OFEC) block for transmission with the first OFEC blocking including a first plurality of checksums distributed throughout a payload area of the first OFEC block;
- and
- circuitry configured to receive a second OFEC block with the second OFEC blocking including a second plurality of checksums distributed throughout a payload area of the second OFEC block, and to mark error locations based on the second plurality of checksums.
