Starting in 2015, we began R&D on high-frequency cable-related equipment, focusing on a zero-tension taping machine (also known as a taping or winding machine). With the widespread adoption of 5G technology and the growing application of next-generation information technologies — including cloud computing, big data, high-end software, information communication and network equipment, the Internet of Things (IoT), and smart city solutions, as well as network information security — conventional 40G QSFP assemblies can no longer meet the rapidly evolving demands of high-speed communications. High-speed cables such as 100Gbps QSFP and 200Gbps QSFP-DD have emerged accordingly.

These ultra-high transmission speeds demand superior electrical characteristic stability, which in turn requires higher precision and stability from manufacturing equipment. To address this challenge, we invented a zero-tension active tape-feeding spindle structure, effectively resolving instability issues in the taping process that could compromise electrical performance. This invention is protected under our patent (Patent No.: 202010530937.5).
