Open the CIPO recordAbstract From the Canadian patent
A method of making an optics package is described in which an exposed length of optical fibre (10) is deliberately subject to a predetermined bend. The relationship between the exposed length of the optical fibre and a distance between a location at which it is supported (P2) and a fixing point (P1) on an optical device (4) is determined taking into account the induced strain in the optical fibre. An optics package designed according to the method is also set forward.

Why it's free to use
- Filed May 12, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 12, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 12, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
