Fujitsu Demos Open ROADM Interoperability in AT&T Field Trial

Fujitsu completed an Open ROADM interoperability field trial on AT&T’s network using the Virtuora multivendor software-defined networking solution and 1FINITY open hardware platform.

The trial was an extension of the Open ROADM Multi-Source Agreement (MSA), which defines interoperability specifications for Reconfigurable Optical Add/Drop Multiplexers (ROADMs), including the ROADM switches, transponders and pluggable optics. The goal of the MSA is to move away from a traditionally closed ROADM optical transport network and toward a disaggregated open transport network, while allowing for centralized software control.

The multivendor field trial consisted of a 100 Gbps optical wavelength in the Dallas metro area carrying live customer traffic. Fujitsu provided transponders and ROADMs from their 1FINITY open hardware platform (1FINITY T300, 1FINITY L100/L110) connecting to high capacity IP/MPLS routers. The 100G wavelength was provisioned using the Virtuora SDN Network Controller, which was integrated into the AT&T ECOMP architecture via REST APIs.

“As an Open ROADM MSA member, Fujitsu shares our customers' vision for software-defined optical networks,” said Rod Naphan, chief technology officer at Fujitsu Network Communications, Inc. “Our 1FINITY hardware and Virtuora multivendor software platforms were designed based on the principles of openness, scalability and interoperability – which translate to cost savings, faster services deployment and improved network performance for service providers. We will continue striving to help customers like AT&T achieve their network vision.”

AT&T Activates First Open ROADMs with Ciena and Fujitsu

AT&T recently activated a 100 Gbps wavelength in its production network in the Dallas area that uses Open ROADM-compliant technology. Specifically, AT&T connected 2 high capacity IP/MPLS routers with transponders and ROADMs provided by Ciena and Fujitsu.

Open ROADM project is a project underway with the backing of AT&T and a goal of driving faster innovation and open software control for the Reconfigurable Optical Add/Drop Multiplexers (ROADMs) used in optical transport networks. An Open ROADM Multi-Source Agreement (MSA) defines interoperability specifications for Reconfigurable Optical Add/Drop Multiplexers (ROADM). Included are the ROADM switch as well as transponders and pluggable optics. Specifications consist of both Optical interoperability as well as YANG data models.

In a blog posting, Andre Fuetsch, President of AT&T Labs and CTO, said the newly installed ROADMs support full software control according to the published Open ROADM specification. NetConf/YANG APIs are used for controlling and managing the optical network. The 100G wavelength was provisioned using an SDN ROADM Controller developed by Fujitsu and integrated into the AT&T ECOMP architecture.
