Abstract
We report a numerical investigation on the transmission techniques
to achieve the highest capacities for nx 40-Gb/s systems and such results
are used to design the lightpath distribution in a European network
operating with Tb/s traffic. We consider the return-to-zero (RZ)
transmission assuming different pulse duration to reach the highest
capacity both in the case of single-channel and of wavelength-division
multiplexing. We assume the transmission in links encompassing G.652
optical fibers since they are the most installed in the world, considering
the compensation of the chromatic dispersion with optical-fiber gratings.
Both the amplification with erbium-doped fiber amplifier (EDFA) and hybrid
Raman/EDFA is considered. We use a novel algorithm for wavelength
assignment in optical networks, taking into account both the traffic
requirements and the physical impairments of the networks that manifest in
the signal transmission. The algorithm is based on the technique of the
removing lightpaths. We report an application for a Pan European network
with 26 nodes.
