Verizon Business announced it has completed a field trial of near real-time circuit provisioning across a multi-vendor optical control plane environment on its commercial network. The trial sent test traffic through optical circuits on the telco's core network from Chicago to Atlanta, using in its course the Ciena CoreDirector, the Fujitsu FLASHWAVE 4500 MSPP and Tellabs 7100 Optical Transport System.
Each supplier collaborated with Verizon engineers during the test to interoperate using industry standards and to jointly reach agreement in areas where standards left gaps. Verizon has led interoperability trials in the past through its own interoperability lab, and the company also has participated in lab demonstrations of optical control plane technology. But this is the first multi-vendor field trial implementation across a commercial network, Verizon said.
"Control plane technology is a critical next step in the evolution of optical technology, because it supports the immediacy of service delivery our customers require as they respond to changing business demands," said Mark Wegleitner, senior vice president of technology for Verizon, in a press release. "Multisupplier interoperability for this emerging capability is critical to Verizon's strategy of building a network as flexible and diverse as possible."
The announcement comes as Verizon, along with partner Nokia Siemens Networks, also was due to present a paper at the European Conference on Optical Communications in Brussels, Belgium, this week, reporting the carriers' latest advances on extending the distance of 100 Gbps transmissions.
