“…75 In addition, high capacity transmission experiments have also been demonstrated without soliton control. 76,77 The dispersion-tuned synchronous modulation technique has also been reported as an alternative to delay time control. 78 When the in-line modulation method is used, it is highly advantageous to increase the bit rate as it is similar to laser mode locking at an ultrahigh repetition rate.…”

“…The key to successfully increasing the system performance from 100 to 160 Gbit/s is the adoption of a polarization scrambler and a phase modulator at the input. [75][76][77] The amplifier spacing was 50 km and the average fiber loss for one span was 12.5 dB. We used eight wavelength-stabilized cw LDs which were equally spaced between 1552.0 and 1562.5 nm at 1.5 nm intervals.…”

Recent progress on time-division multiplexed (TDM) and wavelength-division multiplexed (WDM) soliton transmission is described, in which dispersion management plays an important role in increasing the power margin and the dispersion tolerance. The characteristics of the dispersion-managed soliton are compared with those of return to zero and nonreturn to zero pulses. With a small dispersion swing, the system can still be described as an average soliton using the nonlinear Schrodinger equation, while with a large dispersion swing, the solitonlike steady-state pulse becomes a chirped Gaussian pulse, in which the governing equation is closer to a linear Schrodinger equation with a parabolic potential well. We describe an in-line modulation scheme for up to 80 Gbit/s per channel and its two channel WDM transmission over 10 000 km. Finally, we describe 640 Gbit/s (40 Gbit/sx16 channels) WDM soliton transmission over 1000 km with a dispersion-managed single-mode fiber. (c) 2000 American Institute of Physics.
