Abstract
A data transport card comprising an interface to receive high speed data streams from at least one client, and a pluggable conversion module which converts said data streams into optical data signals and couples these optical data signals into at least one wavelength division multiplexing channel for transport of said optical data signals via an optical fibre.
Claims21
A data transport card comprising:
- an interface to receive high speed data streams from at least one client;
- and
- a pluggable conversion module which converts said data streams into optical data signals and couples these optical data signals into at least one wavelength division multiplexing channel for transport of said optical data signals via an optical fibre,
- wherein said wavelength division multiplexing channel has a predetermined bandwidth and comprises a number of WDM subchannels corresponding to a number of received data streams.

A method for transporting data comprising the steps of:
- receiving data streams from at least one client;
- converting said data streams into optical data signals and coupling these optical data signals into wavelength division multiplexing subchannels of at least one wavelength division multiplexing channel for transport of said optical data signals via an optical fibre;
- reconverting the optical data signals received via said optical fibre in the different wavelength division multiplexing subchannels of said at least one wavelength division multiplexing channel into data streams;
- and
- supplying said reconverted data streams to at least one client.
