Latest Patents

One of Xiquan Dai's latest patents is the "Distributed base station signal transmission system and communication system." This invention provides a solution that includes a first multiplexing and demultiplexing unit, which is designed to multiplex a downlink signal emitted by the base band unit and output it to the remote radio unit. Additionally, a second multiplexing and demultiplexing unit is configured to multiplex an uplink signal emitted by the remote radio unit and output it to the base band unit. The system also features a first colorless optical module that receives and parses the uplink signal to generate the downlink signal, and a second colorless optical module that performs the reverse function. This innovative approach requires only one or a pair of fibers for interconnection between base band units and remote radio units, eliminating the need for a large number of fibers and a metro wavelength division multiplexing network.

Another notable patent by Dai is the "Optical module and fabrication method thereof." This optical module comprises an optical component, a substrate, and a laser, along with an electro-absorption modulator and a semiconductor optical amplifier that are integrated on the substrate. The electro-absorption modulator is strategically placed between the laser and the semiconductor optical amplifier, allowing for efficient signal modulation and amplification. The optical component is designed to deflect and converge the amplified optical signal, ensuring optimal output.
