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

In dense wavelength-division-multiplexed transmission with strong dispersio n management, most pulses inevitably have many partial collisions with puls es of an interacting channel. These partial collisions, in conjunction with the effects of complete collisions, tend to produce unacceptably large tim ing jitter in high-bit-rate, long-distance transmission. With the use of fr equency-guiding filters, however, the timing jitter is dramatically reduced and tends to remain indefinitely clamped to acceptably small levels.
