Open the CIPO recordAbstract From the Canadian patent
An optical switch for fast cell-switching networks comprises an optical interconnection network and an electrical control network. In order to fully exploit optical component capabilities and to overcome the constraints imposed by operating speed limits of electronic components, each input of the interconnection network is associated with components which form aggregates of cells which are to follow a similar path through the interconnection network and time-compress the aggregates and each output is associated with components for the time expansion of the aggregates and separation of the aggregated cells.

Why it's free to use
- Filed June 14, 1993 and granted June 24, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 14, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 14, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
