Abstract
A reconfigurable electrical add/drop multiplexing node, a network, and optoelectronic integrated circuit form a novel high capacity fiber-optic integrated transmission and switching system with a baseline target capacity in excess of 1 Tbps. The node, network, and circuit can leverage optoelectronic integration of transmission and switching components along with using the full “transparency” window of modern optical fibers from about 1270 nm to about 1670 nm for a large number of relatively low-rate wavelengths. The electrical switching fabric can be part of a Reconfigurable Electrical Add/Drop Multiplexer (READM) with similar functionality as a Reconfigurable Optical Add/Drop Multiplexer (ROADM) except in a highly integrated fashion with the transmission components. The electrical switching fabric can implement flow switching on a composite signal to provide comparable functionality to optical components in electrical circuitry such as in Complementary metal-oxide-semiconductors.
