Abstract
The invention concerns a fiber optic soliton signal transmission system comprising a signal amplifier means and signal regenerator means, in-line first filter means and second filter means associated with the regenerator means, the second filter means being different from the first filter means. Independent optimization of the in-line filter means and the filter means associated with the regenerator improves the performance of the transmission system. In the case of wavelength division multiplexed systems, the invention reduces the effects of jitter induced by collisions between solitons.

A fiber optic soliton signal transmission system comprising signal amplifier means and signal regenerator means, in-line first filter means and second filter means associated with the regenerator means, the second filter means having different filter characteristics from the first filter means and applying selective losses to the soliton signal thereby improving the regeneration.
A method of transmitting soliton signals including a step of amplifying the soliton signals, a step of of regenerating the soliton signals, an in-line filtering step effected by a first filter means filtering said soliton signals, and a regeneration filter step effected by second filter means filtering said soliton signals, wherein said second filter is different from the first filter means.
A fiber optic soliton signal transmission system comprising:
- a signal amplifier;
- a signal regenerator;
- an in-line first filter;
- and
- a second regeneration filter, wherein the second filter applies selective losses to soliton signals for improved regeneration.
