Adtran launches 10G-EPON virtual remote OLTs

Optical access equipment specialist Adtran has expanded its software-defined access (SD-Access) portfolio with an environmentally sealed and compact 10G-EPON virtual remote optical line terminal (R-OLT) unit.

Aimed at cable operators looking to upgrade their networks with fibre to the home and distributed access architectures (DAA), these new elements make it possible for them to implement the latest technologies, while seamlessly integrating into their existing DOCSIS back office provisioning and operational systems.

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.
