Open the CIPO recordAbstract From the Canadian patent
An optical fiber mechanical splice comprises a pair of gripping members (110 140) and a resilient biasing member (150). Each gripping member has a plastically deformable gripping surface (124 142). One of the gripping surfaces has a v-groove (144) for receiving and aligning optical fiber ends. The resilient biasing means acts between the gripping members to resiliently bias the gripping surfaces of the gripping members toward one another. In use of the mechanical splice the gripping surfaces are urged, toward one another with optical fiber ends in abutting alignment in the v-groove. The gripping surfaces plastically deform around the fiber ends to provide a larger area of contact between …

Why it's free to use
- Filed May 30, 1991 and granted April 15, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 30, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 30, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
