For a high-speed metropolitan area network (MAN), a ring network based on the wavelength-division multiplexing (WDM) technology has been deployed to solve global information explosions in the Internet. To enhance the network performance, we have studied the node configuration problem, particularly for the one with the double-ring architecture where each node is equipped with fast-tunable transmitters...
The wavelength-division multiplexing (WDM) technology has been extensively studied as a key technology to solve global information explosions. WDM multiplexes plural signal paths using different wavelengths into one optical fiber. Among WDM-based network architectures, this paper focuses on a double-ring network for a next-generation metropolitan area network (MAN). Each node is normally equipped...
A novel gain-clamping technique that controls the amplifier output power of the gain-clamp light by the ALC mechanism is proposed and experimentally confirmed. It yields signal-light gain controllability and stability in burst-mode PON signal amplification.
