A system of interconnected functionally identical modules for switching P optical signals to P locations in a non-blocking manner is disclosed. Each of the functionally identical modules provides a same function, which may or may not be provided in an identical manner. Each module has several of first ports and several second ports optically coupled to second ports of other modules. Switching means are provided for switching means for switching between the first ports and the second ports. Each module has at least a second port directly coupled to another second port. Providing a system wherein modules are identical provides numerous advantages. The architecture further provides the advantage of ease of repair within no disturbance to communications being handled by othermodules.

L'invention est un système de modules interconnectés fonctionnellement identiques servant à commuter P signaux lumineux à P emplacements sans blocage. Chacun de ces modules fonctionnellement identiques a la même fonction, laquelle n'est toutefois pas nécessairement présentée de la même façon d'un module à l'autre. Chaque module est doté de plusieurs premiers ports et de plusieurs seconds ports optiquement couplés à certains des seconds ports des autres modules. Des dispositifs de commutation sont utilisés pour effectuer des commutations entre les premiers ports et les seconds ports. Dans chaque module, un second port au moins est directement couplé à un autre second port. L'utilisation d'un système à modules identiques procure de nombreux avantages. L'architecture de ce type de système offre de plus l'avantage de faciliter les réparations sans perturbation des communications prises en charge par les autres modules.
