Simulation of the effects of laser clipping on the performance of AM SCM lightwave systems

Hybrid Fiber Radio Systems: Features and Performance

“…Furthermore, even if the laser characteristic was linear above its threshold current, signal distortion occurs also because the laser intensity is occasionally clipped by the large negative excursions of the modulating current. This phenomenon called clipping, gives rise to impulsive noise that deteriorates the system performance [5]. Optical source non-linearity is sketched in figure 2.…”

Performance evaluation of optical fiber link in microcellular mobile communications systems

“…The static intermodulation noise power that falls into the w x ith carrier bandwidth is given by 2 where r q s y t s i, 1 F r s, t F N and a is the third-order 3 parameter of nonlinearity.…”
