Heavyweight! 100Gbps rate space optical communication products on the market!

After two years of research and development, on the morning of May 11, 2022, Wuhan Liubo Optoelectronic Technology Co., Ltd. and Wuhan University Laser Communication Laboratory jointly developed the LB50JAA-15FFF ultra high speed laser communication product, which successfully completed a 100Gbps rate space laser communication test in Wuhan. The communication test distance was 400 meters, and the test lasted for 3 hours, achieving zero error transmission.

The development work of this product has received key support from the 2020 Wuhan Science and Technology Bureau's application foundation cutting-edge project "Key Technologies for High Speed and Long Distance Wireless Optical Communication". The product includes a precision tracking system that can compensate for real-time spot jitter caused by atmospheric turbulence and stabilize the spot, achieving stable communication. Due to the adoption of patented technology for coaxial transmission and reception structures, high-precision ensures the coaxiality of the receiving and emitting axes, enabling precise alignment and stable communication of bidirectional optical paths, and significantly reducing the volume of the system's optical mechanical structure and the complexity of optical axis adjustment.

Experimental scenario diagram

The antenna head of this product adopts a fiber optic transmission mode, which can transmit fiber optic data transparently without being constrained by communication protocols and communication rates. In theory, the bandwidth (T) that the fiber optic can carry can be transmitted. This laser communication experiment uses Huawei OptiX OSN 1800 multi-service optical transmission platform, which synthesizes 10 channels of a single 10Gbps signal into a 100Gbps signal, achieving 100Gbps rate spatial laser signal transmission. This product has the characteristics of light weight, small size, low power consumption, and high stability, and has broad application prospects in fields such as 5G and 6G communication.
