A one million km soliton transmission was achieved in 1991 through the use of soliton controls in the time and frequency domains . Synchronous modulation enables us to retime the soliton pulse position which experiences jitter as a result of amplified spontaneous emission (ASE) noise (Gordon-Haus Jitter ). It is also possible to remove the interaction forces which inevitably occur between closely adjacent solitons. It has been proven theoretically that soliton data transmission over unlimited distances is possible with this technique since periodic synchronous modulation can reduce the ASE noise to a significantly low level .
