Abstract: An optical access network includes an optical hub having at least one processor, and a plurality of optical fiber strands. Each optical fiber strand has a first strand end connected to the optical hub. The network further includes a plurality of nodes connected to at least one segment of a first fiber strand of the plurality of optical fiber strands. Each node is sequentially disposed at respective locations along the first fiber strand at different differences from the optical hub, respectively. The network further includes a plurality of end-points. Each end-point includes a receiver. Each respective receiver (i) has a different optical signal-to-noise ratio (OSNR) from the other receivers, (ii) is operably coupled with at least one node of the plurality of nodes, and (iii) is configured to receive the same optical wavelength signal from the first fiber strand as received by the other receivers.

Abstract: Ein optisches Netzwerk beinhaltet einen Senderabschnitt, der dazu eingerichtet ist, einen digitalisierten Symbolstrom über eine digitale optische Verbindung zu übertragen, eine Mappingeinheit, die innerhalb des Senderabschnitts angeordnet und dazu eingerichtet ist, den übertragenen digitalisierten Symbolstrom mit einem Mappingcode vor der Übertragung über die digitale optische Verbindung zu kodieren, einen Empfängerabschnitt, der dazu eingerichtet ist, den kodierten Symbolstrom von der digitalen optischen Verbindung zurückzugewinnen, und eine Demappingeinheit, die innerhalb des Empfängerabschnitts angeordnet und dazu eingerichtet ist, den wiederhergestellten kodierten Symbolstrom in ein uncodiertes digitalisiertes Signal zu mappen, das dem digitalisierten Symbolstrom am Senderabschnitt vor der Kodierung durch die Abbildungseinheit entspricht.

Abstract: An optical network includes a transmitter portion configured to transmit a digitized stream of symbols over a digital optical link, a mapping unit disposed within the transmitter portion and configured to code the transmitted digitized stream of symbols with a mapping code prior to transmission over the digital optical link, a receiver portion configured to recover the coded stream of symbols from the digital optical link, and a demapping unit disposed within the receiver portion and configured to map the recovered coded stream of symbols into an uncoded digitized signal corresponding to the digitized stream of symbols at the transmitter portion prior to coding by the mapping unit.
