Abstract: Symbol multiplexing Physical Medium Attachment (PMA) may be provided. A plurality of first lanes may be received and then Alignment Markers (AMs) from the plurality of first lanes may be used to determine symbol boundaries and identify the plurality of first lanes. Next, groups of the plurality of first lanes may be de-skewed and checkerboard patterns in the plurality of first lanes may be undone. Then the plurality of first lanes may be symbol-wise multiplexed to a plurality of second lanes. The plurality of second lanes may then be sent.

Abstract: Devices, networks, systems, methods, and processes for determining receiver performance metric of a network device are described herein. A device may utilize one or more error patterns associated with the network device to retrieve one or more symbol errors from the one or more error patterns. The device can determine an error threshold for a segment based on a predefined Bit Error Rate (BER) level for the segment. The device may generate a performance metric for the segment based on the error threshold and the retrieved symbol errors. The device can generate a receiver performance metric based on performance metrics of segments. The device may determine a Code Error Ratio (CER) and can predict a Frame Loss ratio (FLR) associated with the network device based on the CER.
