High-speed soliton transmission in dense periodic fibers

Abstract

An 80-Gbit/s soliton can be transmitted over a cross-Pacific distance in a dense periodic fiber, even in the presence of higher-order effects. Such a dense dispersion-managed soliton is generally more stable and faces fewer mutual interactions than a conventional dispersion-managed soliton.

Design rules for dispersion-managed soliton systems

“…Moreover, the section lengths reduce to only l i % 0:6 km if it is necessary to use larger local dispersion values of AE4 ps 2 =km to avoid four-wave mixing in WDM applications. This result explains why dense dispersion management is a necessity for designing systems at bit rates > 40 Gb/s [4][5][6][7].…”

“…1 represent the loss-less case ða ¼ 0Þ and dashed curves correspond to a loss of 0.25 dB/km in each fiber section. We focus on the case of dense dispersion management [4][5][6][7] in the case of map A and assume that the amplification period…”

Practical design rules for single-channel ultra high-speed dense dispersion management telecommunication systems

“…The propagation distance is therefore mainly limited by intrachannel nonlinear effects such as intrachannel four wave mixing (IFWM) or intrachannel cross-phase modulation (IXPM) [3]- [5]. The second technique, known as "dense dispersion management" (DDM), consists of alternating the fiber dispersion over distances much shorter than the amplification span (typically every kilometer) [6]- [7]. In such systems, pulses propagate with a strongly reduced breathing, leading to a significant reduction of the intrachannel interactions [6].…”

“…In such systems, pulses propagate with a strongly reduced breathing, leading to a significant reduction of the intrachannel interactions [6]. This DDM technique was then considered in several numerical and experimental investigations [6]- [22]. In particular Maruta et al were first to experimentally demonstrate the capacity of this kind of transmission regime through the propagation of a 87-GHz pulse train [12].…”
