Abstract
A metro wavelength division multiplexing network is disclosed and includes a plurality of optical repeaters, connected through an optical-fiber link, each of the optical repeaters having a Raman-gain medium for Raman-amplifying an inputted optical signal, and a semiconductor optical amplifier for amplifying the Raman-amplified optical signal, wherein each of the optical repeaters accepts a pump light having a designated wavelength for pumping the corresponding Raman-gain medium.
