Latest Patents

One of Tomas Valis's latest patents is the "WDM optical network with passive pass-through at each node." This innovative communications network consists of multiple nodes interconnected by an optical transmission medium. The medium is capable of carrying a variety of wavelengths organized into bands. Each node is equipped with a filter that drops a specific band while passively forwarding other bands through the transmission medium. Additionally, a device at each node allows for the addition of a band to the transmission medium. This design enables direct communication between pairs of nodes sharing a common band without the need for active intervention from any intervening node. The network's protocol independence and low losses incurred by passive filters facilitate relatively long path lengths without requiring optical amplification.
