1 Tb/s·km WDM transmission over multimode fibre link

2008

We demonstrate 1 Tb/smiddotkm WDM error-free transmission (highest reported value to our knowledge) over a MMF link by a combination of low-linewidth lasers and central launch.

CSRZ-ASK and DPSK 40 Gb/s All-Raman WDM Transmission Based on UltraWave Fiber

2006

In this paper, we report a complete experimental and numerical analysis of 40 Gb/s WDM ultra long-haul (ULH) transmission using CSRZ-DPSK and CSRZ-ASK modulation formats on UltraWavetrade fiber spans. Experimental results compare well with full numerical simulations

Polarization modulation instability in a Manakov fiber system

2015

International audience; The Manakov model is the simplest multicomponent model of nonlinear wave theory: It describes elementary stable soliton propagation and multisoliton solutions, and it applies to nonlinear optics, hydrodynamics, and Bose-Einstein condensates. It is also of fundamental interest as an asymptotic model in the context of the widely used wavelength-division-multiplexed optical fiber transmission systems. However, although its physical relevance was confirmed by the experimental observation of Manakov (vector) solitons in a planar waveguide in 1996, there have in fact been no quantitative experiments confirming its validity for nonlinear dynamics other than soliton formatio…

Performance Comparison of SSMF and UltraWave Fibers for Ultra-Long-Haul 40-Gb/s WDM Transmission

2007

International audience; We experimentally compare the performance of standard single-mode fiber (SSMF) and UltraWave fiber (UWF) for ultra-long-haul (ULH) 40-Gb/s wavelength-division-multiplexing transmissions. We used the carrier-suppressed return-to-zero amplitude-shift-keying (CSRZ-ASK) and the carrier-suppressed return-to-zero differential-phase-shift-keying (CSRZ-DPSK) formats, which are particularly well-adapted to 40-Gb/s pulse-overlapped propagation. We demonstrate that transmission distance well beyond 2000 km can be reached on UWF with both the CSRZ-ASK and CSRZ-DPSK formats, or on SSMF with the CSRZ-DPSK format only, thus indicating that SSMF-based infrastructure of incumbent car…

Input pulse optimization in wavelength-division-multiplexed soliton transmissions

1997

Abstract Amplitudes of input pulses in different channels of wavelength-division-multiplexed soliton transmissions should be adjusted according to their wavelength shift. The optimal distribution of input amplitudes maintains the initial time width and minimizes the radiations. Numerical simulations indicate that using this simple method, WDM transmission capacities of 80 Gbit/s over transoceanic distances may be possible in dispersion-managed fiber links without introducing any in-line soliton controls.
