Spectral Efficiency Limitation by Fiber Non- linearity in Optical OFDM Transmission Systems
نویسندگان
چکیده
In this paper performance limits of optical OFDM transmission systems are investigated. The maximum achievable spectral efficiency is limited by additive noise of optical amplifiers and non-linear fiber effects. In order to assess this measure, a “weakly nonlinear” system model is used. For a given transmission scenario, there is a minimum power of signal distortion at a specific optical launch power; from this measure an estimate for the maximum achievable spectral efficiency can be deduced.

Performances comparison of a coherent optical OFDM system
This paper addresses OFDM (orthogonal frequency division multiplexing) transmission over optical links with high spectral efficiency, i.e. by using high-order QAM-modulation schemes as a mapping method prior to the OFDM multicarrier representation. Here we address especially coherent optical OFDM modem in long distance. Numerical simulations of the coherent optical orthogonal frequency division...

متن کاملComparisons of spectrally-enhanced asymmetrically-clipped optical OFDM systems.
Asymmetrically clipped optical orthogonal frequency-division multiplexing (ACO-OFDM) is a technique that sacrifices spectral efficiency in order to transmit an orthogonally frequency-division multiplexed signal over a unipolar channel, such as a directly modulated direct-detection fiber or free-space channel. Several methods have been proposed to regain this spectral efficiency, including: asym...
