A recently granted patent (Publication Number: US11966083B2) discloses a communication device designed with specific components to facilitate the transmission and reception of optical signals. The device includes a transmission unit for sending out optical signals, a reception unit for receiving incoming optical signals, a transmission port connected to a first core, and a reception port connected to a second core. An isolator is integrated into the device to allow only transmission optical signals to pass through while blocking signals traveling towards the transmission unit. Additionally, an optical coupler is included to manage the output of transmission and reception optical signals to the respective ports and units within the device.

The key innovation of this communication device lies in the utilization of the isolator and optical coupler to ensure the efficient transmission and reception of optical signals. By allowing only signals propagating in different directions to pass through the cores, the device can effectively manage the flow of optical signals within its components. The optical coupler plays a crucial role in directing the transmission and reception signals to the appropriate ports and units, enhancing the overall functionality of the communication device. This patented technology showcases advancements in optical communication systems, offering a more streamlined and effective approach to signal transmission and reception.
