Open the CIPO recordAbstract From the Canadian patent
An optical assembly has a number of optical fibres (7) which terminate at connectors (3) which connect to short legths of optical fibre (11-18) which connect in turn to an optical back plane (4) mounted within a housing (1). It is desirable to withdraw the connectors (3) from the housing for inspection but this can be difficult as the short fibres (11-18) can be of different lengths. The assembly is therefore provided with a plurality of fixed paths of different predetermined lengths obtained with curved guides of different curvatures.

Why it's free to use
- Filed April 27, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 27, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 27, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
