Latest Patents

One of his latest inventions is a bidirectional optical amplifier arrangement. This invention relates to a bidirectional optical amplifier array that is primarily used in passive optical network (PON) systems. The amplifier is strategically placed between a first line termination (OLT) and a second line termination (ONU). It facilitates the transmission of an optical downstream signal in one direction and an optical upstream signal in the opposite direction. The array consists of two branching and combining units, a unidirectional optical amplifier, and a transponder that separately amplifies the downstream and upstream signals. The bidirectional amplifier maintains a constant gain, ensuring stable operation for the upstream signal regardless of signal bursts.

Another notable patent involves methods and arrangements for improving signal quality. This invention features a bandpass filter mounted downstream of an optical amplifier, which significantly reduces noise. The bandpass filter is designed to optimally receive burst signals transmitted by multiple user devices in a central node. It achieves this by being preset to the respective received carrier frequencies, allowing for efficient signal processing.
