AT&T field tests Open ROADM technology

AT&T's Andre Fuetsch, president of AT&T Labs and the company's CTO, recently revealed in a blog that the service provider has conducted a field trial of Open ROADM technology. The technology initiative aims to promote the development of open standards for ROADMs with advanced software control features (see "AT&T to trial 400 Gigabit Ethernet in 2017").

AT&T's Andre Fuetsch, president of AT&T Labs and the company's CTO, recently revealed in a blog that the service provider has conducted a field trial of Open ROADM technology. The technology initiative aims to promote the development of open standards for ROADMs with advanced software control features (see "AT&T to trial 400 Gigabit Ethernet in 2017").

The trial saw AT&T connect a pair of IP/MPLS routers on its Dallas-area production network with Open ROADM compatible transponders and ROADMs from Ciena and Fujitsu. While Lightwave had speculated originally that Ciena supplied the ROADM technology and Fujitsu the transponders, based on an earlier blog from Fuetsch posted this past March describing the company's Open ROADM work, sources at Fujitsu have subsequently revealed that the company provided not only its T300 transport system but L100/110 ROADMs to the trial as well.

In accordance with the Open ROADM initiative, the transport systems were controlled and managed via NetConf/YANG APIs and information models defined in the Open ROADM Multi-Source Agreement. An SDN ROADM controller developed by Fujitsu and integrated into the AT&T ECOMP architecture provisioned the 100-Gbps wavelength transmitted during the trial.
