CenturyLink trials Adtran’s software-defined access platform

Adtran has announced that US operator CenturyLink is using its virtualised optical line terminal (OLT) in a field trial of next-generation access services.

This is the first US deployment of a disaggregated software-defined access (SD-Access) system, the vendor claims. The virtualised OLT can be programmed to deliver different technologies – in this case XGS-PON and NG-PON2 – from the same hardware, creating a more flexible, manageable and scalable access network infrastructure.

Call Flow picks Adtran-powered XGS-PON for future FTTH roll-outs

Call Flow wants to make a name for itself as the first operator in the UK to offer symmetric multi-gigabit access speeds.

The alternative broadband operator has been building out 100Mb/s fibre-to-the cabinet-based services across Southern England via sub-loop unbundling. To allow services to scale further, it has now decided to adopt a fibre-to-the-home (FTTH) strategy based on the XGS-PON architecture.

To this end, Call Flow has chosen XGS-PON equipment from US optical access systems provider Adtran.
