Based on 4×4 and 8×8 optical switches and static wavelength converters in a novel optical switch matrix, a large capacity intelligent all-optical wavelength cross and converter connect (OWXC) is proposed. It can realize a low crosstalk and low delay zero-blocking probability for a link setup which can reduce cost to 30%. In the intelligent control software, a very simple control frame for control information transportation is proposed along with an optical link setup method by using three kinds of resource lock threshold to realize a classification of service (CoS) of link establishment. The experiment shows that the time from a link blocking to establishing is 22 ms. And it can realize automatic, self-automatic and human modes three link establishment methods. The whole cross capacity is 960 Gb/s with three fibers and 24 wavelengths and zero-blocking probability which is very useful for automatic switching optical network (ASON).
