Abstract
Switching technology may be incorporated into various systems, components, and/or architectures in a fiber optic network to promote network reconfigurability and design flexibility. A signal access unit comprises an input, an output, an access port, a switch arrangement including a switch, and a controller. The switch optically couples the input to the output and not to the access port when in a first configuration, and optically couples the access port to at least one of the input and the output without optically coupling the input and the output together when in a second configuration. The controller is configured to receive an indication of a selected wavelength and to operate the switch arrangement to change the switch between the first and second configurations based on the indication of the selected wavelength.
