Paper Abstract

In optical networks using wavelength routing the ability to assign wavelength channels independently on each link is very useful but to maintain optical transparency then becomes very difficult. In fact optical transparency is not a specific requirement of networks that transmit signals independent of their format. Transponders can provide wavelength conversion if adequate performance can be achieved in the electronic routing of signals independent of format. We demonstrate experimentally a 10 multiplied by 10 matrix switch that is bit-rate, format, and modulation transparent for analogue signals and data at various rates up to 2.5 Gbps. The switch architecture is suitable for use in a wavelength converting transponder node. Prospects for staging these devices at OC-48 and OC-192 rates are discussed.
