Optical phase conjugation in phase-modulated transmission systems: experimental comparison of different nonlinearity-compensation methods.

Optical Phase Conjugation for Dispersion and Nonlinearity Compensation in a 1600km, 42 Gb/s Quasi-Lossless System

We experimentally investigate a long-distance, high-bit-rate transmission system which combines optical-phase-conjugation with quasi-lossless amplification. Comparison with a conventional system configuration demonstrates the possibility of obtaining both dispersion compensation and improved nonlinear tolerance using proposed scheme. ©2009 Optical Society of America OCIS codes: (060.4510) Optic...

Two Means of Compensating Fiber Nonlinearity Using Optical Phase Conjugation

The growing demand of higher capacity over longer transmission distances has seen fiber nonlinearity as a major limiting factor in modern optical transmission systems [1, 2]. Among the methods under investigation, nonlinearity compensation using optical phase conjugation (OPC) has emerged as an effective means of suppressing the nonlinear impairments [3, 4, 5]. This paper shall discuss two type...

Simultaneous nonlinearity suppression and wide-band dispersion compensation using optical phase conjugation.

Optical phase conjugation is demonstrated to enable simultaneous wide-band compensation of the residual dispersion and the fiber nonlinearities in dispersion-managed fiber transmission lines employing slope-compensating fibers. When the dispersion slope of transmission fibers is equalized by slope-compensating fibers, the residual dispersion and the slope of dispersion slope are compensated by ...

uncompensated link with backward-pumped distributed Raman amplification

We present experimental and numerical investigations of Kerr nonlinearity compensation in a 400-km standard single-mode fiber link with distributed Raman amplification with backward pumping. A dual-pump polarization-independent fiber-based optical parametric amplifier is used for mid-link spectral inversion of 5 × 28-GBd polarization-multiplexed 16QAM signals. Signal quality factor (Q-factor) i...
