Latest Patents

One of Harstead's latest patents is titled "Protection scheme for single fiber bidirectional passive optical point-to-multipoint network architectures." This invention provides a point-to-multipoint protected network and related equipment that safeguards against fiber and/or interface failures while minimizing fiber redundancy requirements. The design features a head end connected to a ring network through a passive splitter, allowing the downstream signal to be transmitted in both clockwise and counterclockwise directions. Each network terminal is linked to the ring via an optical circuit that includes a 1:2 optical switch and two passive optical taps, ensuring robust connectivity.

Another significant patent is "Call admission control in cellular networks." This innovation assigns a unique time slot to each wavelength emitted by a centralized wavelength division multiplexed optical source, creating a 'bit interleaved' WDM signal. The developed signal is replicated through multiple stages of amplification and power splitting before data is encoded for various frequency-dependent receivers. This approach allows for efficient data delivery to potentially tens of thousands of subscribers using a limited number of time division multiplexing modulators.
