STL completes PoC for its pFTTx stack with Chunghwa Telecom’s open broadband network

STL’s open source system allows Chunghwa Telecom to use devices and software from different providers, rather than being constrained by single vendor lock-ins.

STL today announced that it has successfully completed its proof-of-concept (PoC) for it programmable FTTx (pFTTx) software solutions with Chungwha Telecom’s open broadband access network.

The PoC collaboration demonstrated how STL’s fully virtualized OLT software stack will enable Chungwha to upgrade its Gigabit Passive Optical Network (GPON) to XGS-PON (10 Gig Symmetric PON). XGS-PON is a fiber access technology for symmetric broadband speeds of upto 10Gbps.

STL’s PoC successfully establishes pFTTx as a fully cloud native disaggregated and open networking compliant solution for last mile fixed access.

Chunghwa Telecom is adopting a virtualized, disaggregated and open access technology to evolve FTTx. STL’s pFTTX – a virtual OLT (Optical Line Terminal) software stack enables Chungwha to transform their FTTx network into a cloud native network architecture. pFTTx leverages white box partner hardware to provide a feature rich solution.

Chris Rice, CEO, Access Solutions, STL, said: “Virtualisation, disaggregation and openness, both in the wired and wireless domains, will shape the network landscape in the coming years. We are very glad to announce the successful integration of STL’s virtualised OLT software stack (pFTTx) into Chunghwa Telecom’s broadband access network. This successful Proof of Concept will go a long way in building and scaling open, disaggregated wired access networks, that will be critical in delivering 5G use cases to millions of customers.”

The trial further establishes connectivity with Chunghwa’s commercial network demonstrating use cases such as BNG (Broadband Network Gateway) integration and live IPTV server integration.

Dr. Lin, the President of Chunghwa Telecom Laboratories, notes that: “To effectively consolidate the potential of development, production, and marketing, while leveraging the 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.”
