DIGITAL SUBCARRIER OPTICAL NETWORK UTILIZING DIGITAL SUBCARRIER CROSS-CONNECTS WITH INCREASED ENERGY EFFICIENCY

摘要

The present invention provides reduced power dissipation and other benefits at the optical transport network layer by utilizing a digital subcarrier optical network comprising multiple digital subcarrier cross-connect switches. This offers several advantages for optical networks, including spectral efficiency and robustness against signal corruption and consumption of less energy than traditional TDM-based electric switches (OTN/SONET/SDH).
