Abstract
An optical reconfigurable service ring (RSR) architecture based on a RSR channel and WDM channel plan matrix, and method for operation in a fiber network that provides WDM wavelength networking functionalities such as provisional wavelength services, optical circuit switching, optical layer 2 packet switching, optical storage switching, and optical layer 3 packet routing, are proposed. In one embodiment, sixteen wavelength are dynamically switching, routed, or distributed among five optical add/drop nodes using narrowly wavelength tunable transmitters and fixed optical add/drop multiplexer modules.
