Paper Abstract

In the past the concept of normalized transmission sections for WDM systems, where each link of a network is divided into equally spaced amplifier sites of 80 km length and appropriate dispersion compensation, has been validated theoretically and experimentally. The advantage of such a concept compared to traditional link design is that from a network point of view the performance along any transparent transmission path within this network can be easily predicted since every section of a path is built by cascading the same building blocks e.g. amplifiers and dispersion compensating fibers. However, for a field deployment in a real network this concept is not very practical, since lengths distribution of the housing stations and spare use of the dispersion compensating fibers along the transmission path, are not considered. In this paper we will compare different approaches to reduce and simplify the design complexity of such optical transmission systems taking into account DCF modules with limited compensation range e.g. DCF-80, DCF-20 or DCF-5 to compensate for 80, 20 or 5 km of standard single-mode fiber and a typical field distribution for the span lengths. As results distributions of the system penalty are analyzed for the different cases and specified target lengths for e.g. a national European network of 800 and 1600 km length with field values for the amplifier sites to guarantee a robust system design taking into account dispersion, fiber nonlinearity and amplifier noise.
