Abstract
In OCDM systems, optical signals have hitherto been transmitted to the receiving end in the optical transmission channel assigned at the transmitting end. This type of transmission is rigid and makes possible only simple network topologies, such as, for example, point-to-point. The object of the invention is to make possible a flexible allocation of channels. The code converter according to the invention serves to convert an optical signal from a first optical transmission channel to a second optical transmission channel, and includes a first optical filter for filtering the first optical transmission channel, an optical broadband source and a second optical filter for filtering the second optical transmission channel.
Claims6
An optical OCDM code converter for converting an optical signal from a first optical transmission channel to a second optical transmission channel, comprising:
- a series connection of a first optical filter for filtering the first optical transmission channel, an optical coupler and an optical broadband sources;
- and a second optical filter for filtering the second optical transmission channel that is connected to the optical coupler,
- wherein the second optical transmission channel differs from the first optical transmission channel.
