%X Based on the theory of queue, a blocking probability model M/M/T/T is presented for a simple and cost-effective architecture of all optical wavelength router to investigate the blocking probability of the wavelength router in WDM wavelength routed all-optical network. It is found that the blocking probability is relevant to the number of wavelength per link and the number of access fiber link ports, and with or without wavelength conversion. Especially, more attention is paid to the blocking performance of the router with limited wavelength convertible capability. And it is seen by the numerical computing that low conversion degree of the wavelength converter is more realistic to construct a wavelength router system with accurately tunable devices not used, not only switching time is to be minished, but also the complexity of carrying out in engineering is reduced.
