After a long absence, the Shenzhen World Exhibition & Convention Center is once again packed with industry partners from all over the country who have come to chase the "light". This time, ETU-LINK Optoelectronic Communication, is here with a full suite of equipment. Booth: 13A09.

Our booth, meanwhile, was already in full swing. 800G and 400G high-speed optical modules, DAC/AOC high-speed cables, and computing power interconnection solutions were neatly displayed, awaiting inspection. Many passing peers and customers were attracted by the exhibits and stopped to discuss everything from the high-speed requirements of computing power data centers to the implementation of customized solutions. Sales partners warmly received visitors, and technical experts provided online "problem-solving," leading to lively discussions on various technical topics. A face-to-face meeting. I was pleasantly surprised to bump into many old friends I hadn't seen in a long time, exchanging pleasantries and chatting; I also met quite a few new partners, exchanging ideas and brainstorming new approaches. Tea was provided in the meeting area, so there was no need to rush; we could sit down and leisurely discuss our needs and explore collaborations. Stealing a moment from our busy schedules, we also became exhibition visitors, wandering through various exhibition halls, listening to industry forums, capturing new trends in the optical communication field, and recharging ourselves. The exhibition has two more days of exciting events left! For those who haven't checked in yet, don't just watch online! Head straight to Booth 13A09 to chat with us about optical modules, unlock more possibilities for high-speed interconnection, and we'll be waiting for you!
