Ultrahigh-Bit-Rate Soliton Communication Systems Using Dispersion-DecreasingFibers and Parametric Amplifiers

摘要

We study analytically and numerically soliton communication links made by use ofdispersion decreasing fibers and parametric amplifiers. We show that bit rates greater than 100 Gbits/s (one channel, one polarization) can be achieved with large amplifier spacings (as high as 120 km). The Raman effect and soliton interactions are compensated through optical phase conjugation, whereas fiber losses and third order dispersion are handled through tailoring of the dispersion profile of a dispersion decreasing fiber.
