Abstract
Abstract A lightwave telecommunications matrix configuration for use in a fiber-optic telecommunications network includes a first set of interface circuits for interfacing with a first external fiber-optic circuit. A second set of interface circuits interfacing with a second external fiber-optic circuit. A plurality of time slot matrices associate between the first and second sets of interface circuits for routing lightwave transmissions within the fiber-optic network. The matrix configuration is optimized for a variety of telecommunication switch architectures, including add/drop matrix, ring, and terminal configurations. Accordingly, the matrix configuration is easily scalable to a wide range of telecommunications network sizes and data rates.
