- Bandwidth improvement using Pulse compression within an electro optic system for high bit rate telecommunications
- Published at:The first GCC Industrial Electrical & Electronics Conference
The dispersive and attenuation properties of multilayer telecommunication line cards are discussed as part of 10 Gbit/s OC192 telecommunications systems. A number of different methodologies are described to compensate for dispersion, attenuation and general signal distortion within high bit rate electro-optic telecommunications systems. This work will report the use of pulse compression techniques to reduce distortion within conventional multilayer circuit boards. This is achieved using a non-linear transmission line which uses the non-linear capacitance-voltage (CV) characteristic of hyper-abrupt Schottky diodes to provide the non-linear function. The development of the Schottky diode based on silicon technology is reported and is explained. The special circuit topology chosen for this circuit enables both rising and falling edge compression. Using this approach the higher harmonic content of fast pulses is reconstructed and signal dispersion in the transmission line is compensated.
