Abstract: A media converter, a system and a method for converting packet based data into serial data and vice versa are provided. The media converter comprises a first interface configured to receive and provide a first type of data stream based on data packets, a second interface configured to receive and provide a second type of data stream based on a continuous serial bit stream, and a signal processor connected to the first and second interfaces and configured to convert said first type of data stream into said second type of data stream and vice versa on the basis of a block encoding/decoding algorithm and a line encoding/decoding algorithm. Thus, enhanced bit error rate may be obtained, thereby allowing the use of optical transmission channels of increased length.

Abstract: An optical modulator has an optical splitter for splitting an input light beam into a first and second light beam; a first and a second wave-guide arm connected to the optical splitter for receiving and transmitting therethrough the first and second light beam, respectively, the waveguide arms each including a core region having group IV semiconductor material or a combination of group IV semiconductor materials; an optical combiner connected to the first and second waveguide arm for receiving the first and second light beam and combining them into an output light beam; a first and a second electrode structure associated with the first and second waveguide arm, respectively; and a driving circuit for supplying voltage to the first and second electrode structure. The driving circuit is adapted to supply a first modulation voltage super-imposed to a first bias voltage to the first electrode structure and a second modulation voltage superimposed to a second bias voltage to the second electrode structure.
