Latest Patents
One of Öberg's latest patents is titled "Path monitoring in optical communication systems." This invention involves an optical communication line equipped with optical fiber amplifiers, including a pump laser. The system is designed to suppress the transmission of optical signals by reducing the power of the pump laser. This allows for monitoring of the line downstream of the amplifier for fiber breaks while minimizing crosstalk with a parallel working line. The light emitted by the standby amplifier is modulated by a low-frequency control tone, which helps in detecting functional connections downstream.
Another significant patent is "Optical WDM network having an efficient use of wavelengths and a node therefor." This invention describes a Wavelength Division Multiplexing (WDM) optical fiber network that consists of two fibers carrying light signals in opposite directions, arranged in a ring configuration. The network includes a standby link that activates if an active link fails. The add and drop node utilizes band blocking filters to manage light power and wavelength channels efficiently, ensuring minimal in-line components and optimal use of wavelength channels.
