Latest Patents

One of his latest patents is titled "Method and system for controlling amplifier power in an optical communications network having add/drop capability." This invention includes a method for controlling amplifier output power in an optical communications network that has channel add/drop capability. The method involves determining a first transmission parameter and a second transmission parameter at a first amplifier. In this exemplary embodiment, the first transmission parameter is a composite express signal-to-noise ratio, while the second transmission parameter is a composite signal-to-noise ratio. The total output power of a downstream amplifier is adjusted in response to these parameters. A system for implementing this method is also disclosed.

Another significant patent is "Method and system for suppressing ASE on a WDM network." This invention provides a method and apparatus for assigning channel bands to a wavelength division multiplexed (WDM) system. The WDM system includes an arrangement of optical amplifiers, banded optical add-drop multiplexers (OADMs) with blocking filters, and a tunable edge filter. The channel band assignment method effectively suppresses amplified stimulated emissions (ASE) in a partially populated system where at least one of the blocking filters is not in the transmission path. The method involves assigning channel bands sequentially from one edge of an amplified transmission window to the other, while adjusting the tunable edge filter to attenuate ASE wavelengths not blocked by the filters.
