For optical fiber communication systems, the nonlinearity effects in fiber are significant impairments that reduce the maximum capacity of the optical network. In most fiber optic communication system, the significant nonlinearity effects we encounter is the Scattering effect and the Kerr nonlinearity that comes into play when there is a variation of the refractive index in the core and cladding of the fiber due to the signal intensity, which gives rise to SPM, XPM, FWM non-linear effects. In this paper, the symmetrical-symmetrical-post compensation technique has been implemented for the compensation of the FWM. An efficient 4, 8, 16, and 32-channel RoF system with Bessel filter incorporation has been illustrated. This system provides efficient results for the channel spacing (75GHz), launch power (20 mW), and no. of input channels (8).

摘要

For optical fiber communication systems, the nonlinearity effects in fiber are significant impairments that reduce the maximum capacity of the optical network. In most fiber optic communication system, the significant nonlinearity effects we encounter is the Scattering effect and the Kerr nonlinearity that comes into play when there is a variation of the refractive index in the core and cladding of the fiber due to the signal intensity, which gives rise to SPM, XPM, FWM non-linear effects. In this paper, the symmetrical-symmetrical-post compensation technique has been implemented for the compensation of the FWM. An efficient 4, 8, 16, and 32-channel RoF system with Bessel filter incorporation has been illustrated. This system provides efficient results for the channel spacing (75GHz), launch power (20 mW), and no. of input channels (8).
