An Eight-Wavelength 160-Km Transparent Metro WDM Ring Network Featuring Cascaded Erbium-Doped Waveguide Amplifiers

We demonstrate an 8x2.5 Gb/s Wavelength-division-multiplexing metropolitan ring network in which each network-sourced wavelength constitutes a distinct multiuser virtual ring. The ring's four nodes feature erbium-doped waveguide amplifiers, which promise future integrability.
