STL has completed a proof-of-concept (PoC) for its programmable FTTx (pFTTx) software with Chunghwa Telecom’s open broadband access network.

The PoC showed how STL’s virtualised Optical Line Terminal (OLT) software stack enables Chunghwa to upgrade its Gigabit Passive Optical Network (GPON) to XGS-PON (10 Gig Symmetric PON) - a fibre access technology for symmetric broadband speeds of up to 10Gbps.

At the same time, it establishes pFTTx as a fully cloud native, disaggregated and open networking compliant solution for last mile fixed access. 

“Virtualisation, disaggregation and openness, both in the wired and wireless domains, will shape the network landscape in the coming years,” said Chris Rice (pictured), CEO of access solutions at STL.

“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.”

As the largest integrated telco in Taiwan, Chunghwa Telecom is looking to evolve FTTx and adopt a virtualised, disaggregated and open access technology. As such, STL’s pFTTx solution enables Chunghwa to transform their FTTx network into a cloud native network architecture, using white box partner hardware to provide a feature rich solution.

In addition, the trial further established connectivity with Chunghwa’s commercial network demonstrating use cases such as Broadband Network Gateway integration and live IPTV server integration.

"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,” said Dr Lin, president of Chunghwa Telecom Laboratories.

“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."

Additionally, STL’s open source system enables interoperability allowing Chunghwa Telecom to use devices and software from different providers.
