“…With the development of optical fiber amplifiers, 1R (reshaping) repeating transmission methods for transmission distances of 1000 km or more are being studied [1,2]. Problems in such transmission systems are optical nonlinear effects in the fibers due to the use of optical fiber amplifiers (FWM: four-wave mixing; SBS: stimulated Brillouin scattering; and SPM: self-phase modulation) and the polarization mode dispersion and chromatic dispersion [3,4].…”

The development of optical fiber amplifiers has spurred study of the 1R (reshaping) repeating transmission method for transmission distances over 1000 km. As transmission distances become longer, there is the possibility that polarization mode dispersion and chromatic dispersion will limit transmission distances. In particular, polarization mode dispersion can be altered by the ambient temperature, cable structure, and situation of installation. The effects of such factors with respect to the polarization mode dispersion in submarine optical fiber cables have not been sufficiently clarified. Therefore, in this article, the authors investigate the polarization mode dispersion by using a submarine optical fiber cable with 12 fibers roughly 10 km in length to clarify the characteristics of a submarine optical fiber cable for application in long‐distance transmission systems with optical fiber amplifiers. The results show that there is a correlation between the changes in the polarization mode dispersion after each cable manufacturing process and the change in the strain, as well as accompanying changes in lateral force. Finally, the temperature dependence (from 5 °C to 30 °C) of the polarization mode dispersion is also described. © 2000 Scripta Technica, Electron Comm Jpn Pt 1, 83(8): 76–84, 2000

“…A large amount of theoretical and experimental study has been devoted to very long span optical systems (with a span within 1500-9000 km) also considering WDM and FDM [5][6][7]10]. If FDM links with a span within 200-600 km and a capacity of a few hundreds of Gbit/s are considered, a certain number of experimental results have been published [8,9]; however, at the author's knowledge, an accurate theoretical analysis is still lacking.…”

In this paper the performance of FDM systems with a capacity of the order of a few hundreds of Gbit/s and a span up to 500 km is analysed by means of an analytical model. These systems can be important in the future high speed digital optical network.The comparison between IM-DD and coherend systems gives quite different results if transoceanic single channel systems or very high capacity FDM systems with a span of a few hundreds of km (300-500 km) are considered. While in the first case it is well known that IM-DD exhibits better performance the situation is different in the second case. Coherent systems exhibit better performance: up to 300 Gbit/s can be transmitted over a distance of 500 km adopting homodyne PSK technique.

Extension of the Transmission Length of Optical FDM System by using Distributed In-Line Group-Delay Equalizers

Optical frequency division multiplexing (FDM) transmission systems are promising to realize the large capacity. In such optical FDM transmission systems, the fourwave-mixing (FWM) occurs as a serious limiting factor. The FWM can be suppressed by the fiber dispersion, however, which must be compensated by the group-delay equalizers.In this paper, an optical FDM transmission system of equally spaced channels with the distributed in-line group-delay equalizers is proposed and evaluated by the computer simulations. The simulations show that in the optical FDM transmission system with the distributed in-line equalizers, both the FWM and the random interaction between the fiber dispersion and the XPM/SPM can be suppressed effectively. Consequently, the system makes the transmission length about 2.2 times longer than that of the systems with one receiving-end equalizer. Moreover, among the methods for realizing the middle-haul and large capacity systems, the optical FDM transmission system with the distributed in-line equalizers has been confirmed to be most promising.
