Abstract

Method for coordinating measurements and calibrations in a passive optical network, PON, in particular in a Gigabit PON, the method comprising: generating, in an optical line termination (3), OLT, a downstream frame (25), transmitting the downstream frame (25) from the OLT to a plurality of optical network terminations (6.1 to 6.n), ONTs, the downstream frame (25) comprising at least one allocation structure (10) for allocating to at least one targeted ONT (6.1 to 6.n) a time slot for transmitting upstream data, the allocation structure (10) indicating that the type of upstream data to be transmitted during the allocated time slot is measurement data (26) or calibration data.
