Latest Patents

Fredrik Lidén holds a patent for "Path monitoring in optical communication systems." This invention involves an optical communication line equipped with optical fiber amplifiers, including a pump laser. The technology 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 invention also eliminates the risk of confusing reflections from a working line with light emitted by the standby amplifier. The light emitted by the standby amplifier is modulated by a low-frequency control tone, which helps in monitoring the functionality of the connection downstream of the amplifier.
