Title: The Innovations of Doutje Van Veen
Introduction
Doutje Van Veen is a notable inventor based in New Providence, NJ (US). He has made significant contributions to the field of optical communications, holding a total of 7 patents. His work focuses on enhancing the efficiency and performance of optical networks.
Latest Patents
One of his latest patents is the "Presetting equalizer for burst mode optical receiver." This invention introduces a technique for presetting the tap values of the equalizer component of an Optical Line Terminal (OLT) burst mode receiver. The goal is to eliminate or shorten the conventional equalizer training period, which typically delays the transmission of useful data from the Optical Network Unit (ONU) to the OLT. The technique relies on three known frequency responses: the ONU transmitter response, the OLT receiver response, and a specific fiber frequency response calculated for the span connecting the transmitter and receiver.
Another significant patent is the "System and method for multimodulation in a passive optical network." This invention allows an OLT in a flexible passive optical network (PON) to transmit a downstream signal using two or more modulation formats. At least one of these formats is a modified PAMx modulation format, where x is greater than 2. This modified modulation encodes data bits in a way that alters the probability of specific transitions between amplitude levels, enhancing the overall performance of the network.
