Beschreibung
Zusammenfassung:	An apparatus (802) for transmitting and a method for use in a transmitter of a passive optical network, PON, (810) wherein the method comprises: sending a first frame of a first modulation format that is suitable for a first group of receivers before sending a second frame of a second modulation format that is suitable for a second group of receivers, wherein the first modulation format is a higher modulation format than the second modulation format, and wherein the method further comprises inserting into the first frame at least one symbol of the second modulation format at at least one outer edge of the first frame. An apparatus (804) for receiving and a method for use in a receiver of a passive optical network, PON, (810) wherein the method comprises: receiving a first frame of a first modulation format that is suitable for a first group of receivers before receiving a second frame of a second modulation format that is suitable for a second group of receivers, wherein the first modulation format is a higher modulation format than the second modulation format, and wherein the method further comprises treating at least one bit related with at least one symbol in the first frame at at least one outer edge of the first frame as unknown.
