Title:
RECONFIGURABLE POINT TO MULTIPOINT CONNECTIONS
Document Type and Number:
WIPO Patent Application WO/2019/138246
Kind Code:
A1
Abstract:
There is presented an apparatus for use with a Wavelength Division Multiplexed Passive Optical Network (WDM-PON). The apparatus comprises an electronic controller, optical transmitters and a wavelength multiplexer. The electronic controller is configured to receive first input electrical data signals, output electrical data signals on data channels based upon the input electrical data signals and change the data rate of at least a first of the output electrical data signals. The optical transmitters, which receive the electrical data signals, are each configured to receive, respectively on different data channels, electrical data signals output from the electronic controller. The optical transmitters output light signals corresponding to the received electrical data signals from the electronic controller. Respective light signals of each optical transmitter are centred on a different wavelength to the light signals of the other optical transmitters. The wavelength multiplexer is configured to receive the output light signals from the optical transmitters and output a wavelength multiplexed optical output signal.
