Soliton collisions in wavelength-division-multiplexed dispersion-managed systems

In dense wavelength-division-multiplexed transmission with strong dispersion management, most pulses inevitably have many partial collisions with pulses of an interacting channel. These partial collisions, in conjunction with the effects of complete collisions, tend to produce unacceptably large timing jitter in high-bit-rate, long-distance transmission. With the use of frequency-guiding filters, however, the timing jitter is dramatically reduced and tends to remain indefinitely clamped to acceptably small levels. (C) 1999 Optical Society of America.
