Abstract:
A method for providing multiple classes of services on a communication platform through a Wavelength Division Multiplexing optical network, the optical network having a plurality of user terminals connected thereto, the method comprising:selecting a predetermined group of light channels; partitioning one or more subsets of light channels from the predetermined group of light channels based on the light channels' wavelengths; enabling each user terminal to monitor an availability of one or more orthogonal codes from a predetermined set of orthogonal codes shared by the predetermined group of light channels, wherein each orthogonal code is for modulating a light channel to provide communication services; selecting at least one available orthogonal code; and orthogonally modulating a light channel using the selected available orthogonal code, wherein each partitioned subset of light channels is used for supporting a class of service on the optical network.
