EN A new control algorithm for multi-plane banyantype switching fabrics has been proposed recently. It has been shown that using this algorithm such switching fabrics can be wide-sense nonblocking (WSNB) when the number of planes is lower than for the strictly nonblocking (SNB) one, and for even number of stages the WSNB switching fabric requires the same number of planes as rearrangeable one. The considered algorithm and WSNB conditions did not take into account crosstalk constraint, which is an important factor in photonic switching. This paper enhanced this algorithm to the case when the first order crosstalk in the switching fabric is not allowed. WSNB conditions for this enhanced algorithm are also derived. It is shown that the number of planes required is less than those derived earlier in other papers for WSNB multiplane banyantype switching fabrics under crosstalk constraint.
