Demonstration of high capacity in the LAMBDANET architecture: a multiwavelength optical network

Abstract
The letter presents transmission measurements in a multi-wavelength optical network, using 18 channels spaced 2 nm around 1.55 μm. Each channel was modulated at 1.5G bit/s and transmitted through 57.8 km of single-mode optical fibre. Experimental results demonstrate a bandwidth-distance product of l.56 Tbit s−1 km and a point-to-multipoint figure of merit of 21.5 Tbit s−1 km node.
