K. Rottwitt et al., ADIABATIC SOLITON TRANSMISSION AT VERY HIGH BIT RATES, Journal of the Optical Society of America. B, Optical physics, 12(7), 1995, pp. 1307-1310
The dynamic behavior of ultrahigh-bit-rate solitons is studied. We pre
dict the radiated energy from a soliton by employing perturbation theo
ry. The process of loss cancellation is analyzed, and it is shown that
distributed erbium-doped fibers, tens of soliton periods long, provid
e an improved transmission compared with that for lumped amplification
.
