SYNCHRONISATION STRUCTURE OF FRAME OF DOWNLINK OF DATA TRANSFER OF TEN-GIGABIT PASSIVE OPTIC NETWORK PROTECTED WITH ERROR CONTROL IN HEADER

摘要

FIELD: information technology.SUBSTANCE: device containing optic line terminal (OLT) having a possibility of being connected to a variety of optic network modules (ONU) and transferring a variety of frames of downlink transfer to ONU, in which each of the frames of downlink transfer includes a variety of code words of forward error correction (FEC) and a variety of additional non-FEC coded bites that contain synchronisation information protected with a header error control code (HEC).EFFECT: improvement of reliability and efficiency of transfer of data frames.20 cl, 8 dwg
