Xunshi Interview with Yongding Optoelectronics: Open up the layout of the optical device industry to build the future core competitiveness.

ICC News recently visited Jiangsu Yongding Optoelectronics Co., Ltd., which belongs to Wuhan Yongding Optoelectronics Group (hereinafter referred to as Yongding Optoelectronics), which is a subsidiary of Jiangsu Etern Co., Ltd. (stock code 600105, Yongding shares) and is also the core layout of Yongding shares in optical network transmission.

It is understood that in addition to Jiangsu Yongding Optoelectronics Co., Ltd., Yongding Optoelectronics also has several subsidiaries, including Wuhan Yongding Optoelectronics Technology Co., Ltd., Wuhan Yongding Wrui Chuangxin Technology Co., Ltd., Suzhou Dingxin Optoelectronics Technology Co., Ltd., Suzhou Yongding International Trade Co., Ltd., and Chengdu Dingji Information Technology Co., Ltd., which are located in Suzhou, Wuhan and Chengdu respectively.

Mr. Li Xin, general manager of Yongding Optoelectronics, told Xunshi that Yongding Optoelectronics actively cooperated with the research and test of the 5G forward transmission wave division innovation scheme of the three major operators to provide operators and communication equipment manufacturers with a full range of passive wave division multiplexer solutions for 5G forward transmission. For different application scenarios, the company can provide customized temperature-free AWG solutions, pure passive and semi-active CWDM, MWDM, LWDM, DWDM solutions, successfully in domestic and foreign 5G networks in large quantities, to help operators customers 5G deployment, to promote the development of the next generation of optical networks.

For the CWDM scheme commonly used by telecom operators 5G fronthaul, Yongding Optoelectronics can provide cost-effective CCWDM products. Mr. Li believes that compared with traditional three-port CWDM products, CCWDM can better meet the requirements of operators on cost, reliability and optical performance. In terms of core process, CCWDM module adopts thin film filter (TFF) technology and free space packaging technology, which can be used for four or eight channel CWDM wavelength Mux/Demux, and the working wavelength covers 1271-1611nm. In terms of ensuring the competitiveness of CCWDM products, Yongding Optoelectronics improves production efficiency by investing in automation equipment, with a monthly production capacity of 800K ports. At the same time, the company's production line strictly implements standard quality verification, has passed 6500 hours of reliability test and continuous ORT test.

As China continues to improve the coverage of 5G dual-gigabit network, 5G front-pass network, OTN all-optical network, metropolitan area network construction is rapidly advancing, supporting the 5G era of high-speed transmission of optoelectronic chips, optical devices, optical modules and other products demand is increasing. Following the market demand and product development trend of optical communication, Yongding Optoelectronics has successfully introduced mass commercial DWDM thin film filters. Based on high-end coating machines and high-precision production and testing equipment, it adopts advanced ion-assisted deposition IAD technology to achieve ultra-smooth polishing flatness of less than 0.3nm and temperature drift of less than 0.11pm/℃, making the company one of the leading DWDM TFF chip suppliers in the world.

Based on the far-sighted optical communication strategy, Yongding Optoelectronics actively layout the entire industry chain of optoelectronic devices. Li Zong introduced to Xunshi, in the upstream of the industry, relying on the listed company Yongding shares and South Korea WOORIRO to set up a joint venture subsidiary Wuhan Yongding Wushi Core, focusing on AWG passive optical chip research and development and production. At the same time, Yongding Optoelectronics also invested heavily in the establishment of a subsidiary Suzhou Dingxin Optoelectronics, focusing on communication semiconductor VCSEL and DFB lasers and other active optical chips. In the downstream of the industry, Yongding Optoelectronics has set up a subsidiary, Chengdu Dingji Information, to provide technologically innovative DCI (Data Center Interconnection) products through independent research and development of open decoupling WDM equipment and self-developed network management controllers, providing low-cost, low-delay, efficient and simple data center interconnection systems for operators and Internet cloud service providers.

Xunshi believes that with the optical network as the base to build the future all-optical interconnection, all-optical driving, smart family and even the urban ecology of the meta-universe, it is necessary to deploy high-speed, low-delay and more reliable optoelectronic components, and having comprehensive optical device capability will be the key guarantee for people to build the future all-things interconnection ecology. Yongding Optoelectronics will focus on Filter chips, AWG chips and laser chips as a grasping hand, do deep optical communications industry, and gradually and steadily sink into the civilian field. The layout of the whole industry chain from chip to device to module final system integration is the core competitiveness of Yongding Optoelectronics in the market in the future.
