Open the CIPO recordAbstract From the Canadian patent
We have determined that unlike the most multimode silica fiber multimode polymer fiber often exhibits a delay characteristic that has a broad low dispersion region where propagation delay of spatially restricted optical pulses remains relatively constant. This low dispersion region is centered around the center axis of the fiber core as a function of launch position. By directing a transmitted optical pulse to this region we have determined that, optical pulse dispersion can be significantly reduced without the need for using, the prior art technique of using a single mode fiber spliced in series with the, multimode fiber to reduce dispersion. A polymer fiber based optical transmission …

Why it's free to use
- Filed September 22, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 22, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 22, 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.
