Chunghwa Telecom completes proof of concept for Open Access Network
TAIPEI, Taiwan, R.O.C. July 1, 2021 - Chunghwa Telecom Co., Ltd. (TAIEX: 2412, NYSE: CHT) (“Chunghwa” or “the Company”) today announced it completes proof of concept for Open Access Network.
In response to the development trend of software-defined everything, cloud native, and open networking, Chunghwa Telecom teamed up with partner suppliers to demonstrate a multi-vendor Fiber-To-The-Home (FTTH) system as an open access network in Taiwan on June 29th. The system is based on the software functions running on the general cloud infrastructure and the network equipment from local suppliers. Besides providing high-speed broadband access and IPTV/MOD services, it achieves flexible hardware construction and rapid software customization. As the international leading telecoms in the United States and Germany have already developed commercial use cases, Chunghwa Telecom is the first operator in Taiwan to independently carry out multi-vendor integration and successfully verified the open access network architecture.
Based on the experience in FTTH deployment and maintenance, Chunghwa Telecom invited local and global suppliers to participate in this joint effort. By incorporating XGS-PON OLT network equipment of Edgecore, XGS-PON ONU network of Zyxel and Alpha, the virtualized OLT software functions of foreign suppliers Netsia, Radisys, and STL (Sterlite Technologies Limited) (Note), Chunghwa Telecom Laboratories successfully completed the integration of the open access network system; in addition, Chunghwa Telecom Laboratories also evaluated Nokia's virtualized OLT software functions which are compatible with legacy FTTH network. Both approaches have been successfully verified to provide Gbps-level high-speed Internet access and high-quality MODTM (Multimedia On Demand) services.
The verification is based on the telco-cloud architecture, with which we can overcome the limitations of legacy network equipment software and hardware binding. The virtual network functions constructed from software modules that support open interfaces have attracted suppliers to join the open access network market, and the supply chain is gradually taking shape. To further enhance high-speed Internet services and assist local suppliers in expanding to overseas markets, Chunghwa Telecommunications Laboratories will continue its active participation in open source communities and global standards organizations, and develop telco-cloud-related technologies with all partners.
Chau-Young Lin, the President of Chunghwa Telecom Laboratories, notes that: " To effectively consolidate development, production, marketing and technical capability to build a robust ecosystem is not only a challenge but also an opportunity for Chunghwa Telecom. Chunghwa Telecom Laboratories embraces open networking standards and will continue our collaboration with software/hardware partners in exploring the advantages of network infrastructure and cloud architecture." Chunghwa Telecom Laboratories pursues to deepen the open networking capability in various fields. Working with all partners, Chunghwa Telecom Laboratories strive to realize the vision of Open Network.
