Data transmission methods, optical line terminal, optical network unit and readable medium

Abstract

Provided in the present disclosure is a data transmission method in an uplink direction, including: receiving an uplink optical signal; generating, according to the uplink optical signal, second uplink electrical signals in a plurality of channels; and performing, according to an uplink granularity, channel alignment on the second uplink electrical signals in the plurality of channels for recovering and obtaining a target uplink signal after the alignment. Further disclosed is a data transmission method in a downlink direction, including: receiving a downlink optical signal; generating, according to the downlink optical signal, second downlink electrical signals in a plurality of channels; and performing, according to a downlink granularity, channel alignment on the second downlink electrical signals in the plurality of channels for recovering and obtaining a target downlink signal after the alignment. Also provided in the present disclosure are an OLT, an ONU, and a computer-readable medium.

Dependencies are inferred from the claim text.
