Abstract: A data transmission method and a related device. The method includes an OLT obtains a first uplink transmission parameter of a first terminal corresponding to a first ONU. Then the OLT determines, based on the first uplink transmission parameter, a cycle period for performing data transmission with the first ONU, where each cycle period includes an uplink time window and a downlink time window, the uplink time window includes a first uplink transmission timeslot used by the first ONU to send uplink data, and the downlink time window is used by the OLT to send downlink data. Then the OLT sends an uplink grant message to the first ONU.

Abstract: An information processing apparatus includes: a decoding module, configured to receive M first codewords from at least one peer device, where each first codeword includes first service data with a K-unit length and an error correction code with an R-unit length, where the decoding module is further configured to decode the M first codewords to obtain M second codewords, where a length of each second codeword is a sum of the K-unit length and the R-unit length, each second codeword includes second service data with the K-unit length and error correction information, the second service data is error-corrected first service data; and a classification and statistics collection module, configured to determine a bit error rate of the first service data based on the error correction information.
