Abstract :
Eight-wavelength, densely-spaced coherent CPFSK recirculating-loop experiments at 2.5 Gbit/s have been demonstrated over 600 km through 30 cascaded EDFAs. The WDM signals were densely packed in a bandwidth of only 1.4 nm, indicating the effective use of optical frequency resources by coherent schemes
