Research Laboratories

DE502_-_PolyU_Huawei_Joint_LabA joint research laboratory on Optical Interconnection Network and Advanced Computing System was established in November 2016. The joint laboratory between The Hong Kong Polytechnic University and Huawei Technologies Co., Ltd., one of the largest telecommunication equipment vendors in the world aims to provide a platform for academic and research staff as well as students to collaborate with Huawei in various research areas in the University. There are many advanced experimental platforms for research studies on long haul optical communication systems, short reach optical communication systems for data centre interconnects, distributed optical fibre sensing systems as well as advanced optical devices.


The PolyU-Innovation Technology (HK) Audio and Speech Signal Processing Joint Laboratory is established to support and promote the research and education in the area of audio and speech signal processing. This joint laboratory between The Hong Kong Polytechnic University and Innovation Technology (HK) Ltd. is installed with the state-of-the-art audio and speech signal processing equipment such as an industrial graded acoustic room, head and torso simulator, audio analyzer, real-time system emulator, high frequency oscilloscopes and artificial intelligent servers. The laboratory aims at providing students with up-to-date knowledge in the areas of audio and speech signal processing to prepare them for participating in the related industry.
