Abstract
A method and a device for conveying optical data are provided, wherein an optical network unit conveys data to a terminal via dual sideband modulation, wherein the terminal processes only the upper or only the lower sideband received from the optical network unit, and wherein several dual sideband modulated signals from several optical network units partially overlap when being received at the terminal. Furthermore, a communication system is suggested comprising at least one such device.
Claims13
A method, comprising;
- receiving data that has been modulated via dual sideband modulation at a terminal,
- processing only an upper sideband or only a lower sideband of the data received from the optical network unit, and
- wherein several dual sideband modulated signals from several optical network units partially overlap when being received at the terminal.
An optical line terminal device comprising a processing unit, the device including:
- a component for receiving data from at least two optical network units, which data is dual sideband modulated, wherein spectra of the data received from two optical network units overlap;
- and
- a component for processing only an upper sideband or only the a lower sideband of the data received to reconstruct data from one of the optical network units.
An optical network unit comprising a processing unit, the optical network unit including:
- a component for dual sideband modulating and
- a component for transmitting data to an optical line terminal,
- wherein a spectrum of the data transmitted at least partially overlap with at least one spectrum used by another optical network unit such that an upper sideband or a lower sideband received by the optical line terminal can be used to reconstruct data from the optical network unit.
