“…As discussed below, it is yet possible to make the regeneration function and transmission work independently in such a way that any type of RZ signals (soliton or non-soliton) can be transmitted through the system. We refer to this approach as 'black box' optical regeneration (BBOR) [27].…”

“…Fig. 11 shows the BBOR structure enabling the successful association of DM propagation and SM regeneration by SM [27]. The actual experimental demonstration of the BBOR approach and its superiority over the 'classical' SM-based scheme for DM transmission was experimentally investigated in 40 Gbit/s DM loop transmission [31].…”

As optical amplifiers have opened new perspectives for optical communication systems with ultra-high capacities and longhaul transmission distances (more than 1 Tbit/s over 10 000 km), fundamental limits are being reached. In order to overcome these propagation impairments, another technology revolution is soon required. Promising developments concern in-line alloptical regeneration, which makes it possible to transmit optical data over virtually unlimited distances. In this article, we recall the basic principle of Optical Regeneration in optical communication systems and review the current technology alternatives foreseen for future 40 Gbit/s transmission system implementation. The alternative offered by opto-electronic regeneration is also discussed, as to identify and highlight the advantages of the all-optical approach. To cite this article: O. Leclerc et al., C. R.

RésuméL'avènement des amplificateurs optiques ayant ouvert de nouvelles perspectives pour les systèmes de communications optiques ultra longue distance et à ultra grande capacité (plus d'un Terabit/s sur 10 000 km), des limites fondamentales semblent aujourd'hui être atteintes. Afin de s'affranchir partiellement des dégradations du signal ayant trait à la propagation, une révolution technologique est devenue nécessaire. A ce titre, les techniques de régénération optique du signal en ligne permettant la transmission de données en optique sur des distances virtuellement infinies ont fait l'objet de récents développements prometteurs. Dans cet article, nous introduirons les principes de base de la Régénération Optique dans les systèmes optiques et nous détaillerons les différentes technologies envisagées pour son implantation dans les futurs systèmes de transmission à 40 Gbit/s. La solution offerte par la régénération opto-électronique sera aussi abordée afin notamment d'identifier et de mettre en avant les avantages des approches tout-optiques.

“…A possible implementation for all-optical regenerator involves in-line synchronous intensity/phase modulation (SM) and optical narrowband filtering (NF), as initially proposed in Though optical regeneration by SM/NF intrinsically requires nonlinear pulses, soliton transmission through the system is not a prerequisite; indeed, periodic nonsoliton-to-soliton conversion makes possible to apply the regeneration technique, regardless the RZ data type (linear RZ, DM-soliton, CRZ, etc) [6]. Using this regenerator configuration, we demonstrated the theoretical feasibility of 1.28Tbit/s (32x40Gbit/s) transoceanic systems with 0.23bit/s/Hz spectral efficiency [7].…”

The irresistible growth in capacity demand for optical transmission systems calls for an increase in both channel granularity and bit rate, while maintaining signal quality. The document reviews recent developments in the field of all-optical regeneration and show its potential to meet the challenge with costeffective implementation. We also report a 160Gbit/s all-optical regenerator based on the simultaneous optical regeneration of four 40Gbit/s WDM channels in a single polarization-insensitive modulator chip by using an alloptical cad simulation tool. Regenerated transmission with 0.2(bit/s)/Hz spectral efficiency is achieved over 10,000km distance.

“…Effective pulse stabilization can be achieved in quasi-linear systems if the signal pulses propagate for some short distance under conditions such that they approximate solitons and are then passed through a narrow bandwidth optical filter [8]. Pulses are transformed into solitons in a DSF.…”

Abstract-The use of multiple quantum well (MQW) saturable absorbers (SAs) for signal regeneration in periodically amplified fiber transmission systems is explored. A systematic study of signal destabilization resulting from incomplete saturation of MQW SAs used for regeneration, and of means of overcoming such destabilization, is presented.A computer model for MQW SAs, which considers the asymmetric Fabry-Pérot (AFP) cavity structure commonly employed to increase the contrast of such devices, is presented. The model is used to simulate nitrogen-implanted MQW SAs with < 5 ps recovery time in a transmission system. A comparison is made with results previously obtained for a 10 Gb/s standard single-mode fiber (SMF) recirculating loop transmission experiment using MQW SAs and temporary soliton propagation for signal regeneration. The simulations allow the benefits derived from the two parts of the regenerator to be identified, as well as their contributions to the destabilization of the propagating signal. The error-free transmission distance is improved from ∼ 2000 to > 7000 km when the two components are combined.
