Abstract

Various example embodiments of the present disclosure relates to a physical layer, PHY, circuitry for an optical line terminal, OLT, the PHY circuitry being configured to receive a control signal including an identification of a transmitting ONT for pre-loading an equalization configuration associated with the identification of the transmitting ONT. Other example embodiments relate to a medium access control, MAC, circuitry for OLT, the MAC circuitry being configured to determine an upstream allocation map for optical network terminals, ONTs, and to generate a control signal for a PHY circuitry including synchronization information for receiving upstream optical signal bursts from a transmitting ONT and an identification of the transmitting ONT based on the upstream allocation map. Further example embodiments related to an optical line terminal, OLT, and a method therefor.
