AT&T announced it has successfully completed field trials of XGS-PON technology based on a variety of open source specifications. The trials, conducted in Atlanta and Dallas, featured XGS-PON network virtualization based on Open Source Access Manager Hardware Abstraction (OSAM-HA), which apparently is the new name for VOLTHA.

The completion of trial instills confidence in AT&T that people can use lightning-fast internet speeds at homes and businesses. The field tests included multi-gigabit internet traffic transmission, including delivery of AT&T DIRECTV NOW video. The service provider used a virtualized broadband network gateway function to manage subscribers. The exercise also confirmed that XGS-PON and GPON traffic can be delivered together over the same fibre.

XGS-PON is a fixed wavelength symmetrical 10Gbps passive optic network technology. It’s part of our plan to virtualize access functions within the last mile network. The trial is part of AT&T’s efforts to use software defined networking (SDN) and virtualization in its access networks. Use of Open Network Automation Platform (ONAP) software is a key enabler.

AT&T did not reveal the identities of technology vendors who supported the trial.
