1/13/2022, Optical Fiber Online News, on the afternoon of January 8, the Jiangsu Provincial Department of Industry and Information Technology organized experts to hold the 2021 provincial new product and new technology appraisal meeting in ETERN. ETERN's 11 new products and new technologies have passed the appraisal successfully, of which 6 new product prototypes (products) were identified as leading domestically (2 products were domestic first), 2 new product prototypes (products) were identified as international leading and domestic first, 1 1 new product prototype (product) was identified as the international advanced; 1 new technology was identified as the domestic leading; 1 new product was identified as the international leading.

The high-performance 100GHz 4-hop 0 DWDM filter and the high-performance 100GHz DWDM filter developed by ETERN have won the highest evaluation from the appraisal committee. ; In addition, ETERN's compact coarse wavelength division multiplexer is the international leading level. Both products are key optical components in the deployment of 5G fronthaul networks. In this appraisal, ETERN's FTTR indoor wiring photoelectric composite cable and non-metal rodent-proof indoor and outdoor wiring CFU optical cable were rated as the domestic leading and domestic first level; the high stability and high reliability athermal arrayed waveguide grating was rated as the domestic leading level.

ETERN is a time-honored brand in China's optical communication field and one of the earliest listed companies. As an important part of the new development plan of ETERN Group, Etern Optoelectronics has been working hard in recent years, and the new products participating in the appraisal this time embody the development achievements and goals of Etern Optoelectronics. 4-hop 0 DWDM filter has always been a difficult problem in the filter manufacturing industry. Etern Optoelectronics has been working hard over the years, insisting on the spirit of craftsmanship and technological innovation, and finally broke through this technology. The 100GHz DWDM series filter has successfully achieved mass production, In the domestic optical passive device manufacturers can be one step ahead. Not only that, their CCWDM devices have passed 6,500 hours of reliability testing, and they have also made a lot of preparations for automated manufacturing of products, with modern, industrialized, automated, and large-scale production capabilities. The automated production line gives ETERN's CCWDM devices an unparalleled competitive advantage in terms of performance and cost.

It was introduced in the meeting that just a few days ago, China Telecom released a new round of 5G fronthaul wavelength diversity acquisition plan, including the procurement plan for circulators, which was organized by Wuhan Optical Fiber Online more than a year ago. On the WIOF forum, Du Zhe of Shanghai Telecom Research Institute introduced on behalf of Telecom. During the standard formulation and pilot process of this scheme, the ETERN team deeply participated in the new 5G fronthaul scheme of circulator + CWDM proposed by Shanghai Telecom Research Institute: In terms of standards, considering the addition of circulator, the passive wavelength division insertion loss is too large and the Due to the difference in climate between the north and the south, ETERN and the China Telecom Research Institute jointly established the solution of using circulator + CCWDM to meet the working temperature environment to reduce insertion loss and optimize performance indicators; in terms of pilot tests, ETERN won two exclusive bids from 2019 to 2021 Regarding the CCWDM+ circulator project of Shanghai Telecom Research Institute, Shanghai Telecom Research Institute has deployed and used 8 5G base stations in Shanghai, Suzhou, Changzhou, Nantong, etc., and the trial operation data of the current network is good. At the same time, Shanghai Telecom Research Institute released a technical article on "5G Fronthaul Optical Modules and Devices Based on CWDM/Circulator Technology" in November 2020. Up to now, based on this technical solution, Shanghai Telecom Research Institute has deployed CCWDM+ circulator solution pilots in dozens of existing network base stations in Xinjiang and other places across the country. After more than one year of data testing, it has been shown that all are running well.

SGS' Bellcore Reliability Test Report High Temperature

Li Xin, general manager of Etern Optoelectronics, emphasized that in terms of quality: ETERN's CCWDM products have made a lot of efforts in reliability. Multiple reliability verifications such as mechanical vibration, mechanical shock, temperature shock, etc., at the same time, the company has put forward higher challenges for high temperature storage, low temperature storage, temperature cycle, double 85, etc. Up to now, the company's internal temperature cycle, double 85 The two projects have passed 6500 hours of reliability verification and meet the insertion loss variation within 0.5dB. Market: By the end of 2021, ETERN's CCWDM has been recognized by many domestic equipment and module manufacturers, with a cumulative shipment of 200K channels and above, and an annual failure rate of 0.

Finally, Li Xin told the editor: After years of preparation, Etern Optoelectronics is ready to shine in the new year. In both R&D and manufacturing, they are ready. Now that China Telecom's bidding has given them a new opportunity for development, it is time to let more friends in the industry understand the strength of Etern Optoelectronics.
