Open the CIPO recordAbstract From the Canadian patent
In communication systems based on optical networks electrical power flow rates can be adapted to optical flow rates through time-division multiplexing with pulses compressed to form the optical data transmitted. The invention concerns a process for performing pulse decompression at the receiving end by fully optical means. The process consists in: - forming q auxiliary signals (Se-Sh) obtained through modulating by the received signal (S'1) q optical carrier waves of different wavelengths (.gamma.e-gamma.h) and - combining q delayed auxiliary signals (Re-Rh) obtained by applying delays to the auxiliary signals (Se-Sh) such that any two consecutive delayed auxiliary signals (Re-Rh) are …

Why it's free to use
- Filed April 27, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 27, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 27, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
