Abstract
A transmitter for generating, starting from a data-packet traffic at input, flows of information to be conveyed via optical signals with different wavelengths towards a plurality of targets in a communications network, the transmitter including: a destination decoder to identify, for each packet in the input packet traffic, a respective destination target in the plurality of targets; a plurality of emitter modules operating at different wavelengths for converting the electrical signals into optical signals; and a de-multiplexer, which is controlled by the destination decoder and is able to drive the emitter modules by sending selectively to each emitter module the electrical signals corresponding to a given packet of the input packet traffic according to the respective destination target identified by the destination decoder. A serialization module is set upstream of the de-multiplexer for converting the packet traffic into a serial flow of bits. The transmitter also includes an optional transmission optical bus inverter for implementing a source coding on the electrical signals sent to the emitter modules.
