CoAdna recasts Optical Virtual Switch systems for data center interconnect

CoAdna Photonics, Inc. says it has added features to its Optical Virtual Switch (OVS) systems to enhance their applicability to data center interconnect (DCI) links.

The 1RU OVS systems, based on the company's LightFlow wavelength selective switch (WSS) expertise, can enable such ROADM-related functions as wavelength cross connect, directionless add/drop, broadcasting, drop and continue, and others in a much smaller, less expensive package than traditional ROADM systems, CoAdna asserts. The OVS platforms are designed to support pay-as-you-grow deployment in up to 4 degree mesh networks in a metro or regional area and provide built-in fiber protection and wavelength restoration features. The OVS software enables compatibility with software-defined networking (SDN) architectures through support of OpenFlow 1.3/1.5 as well as traditional SNMP, CLI communication protocols.

Use of the OVS systems enables traffic from core switches and muxponders to be reconfigured via SDN for data exchanges with different data centers at different times. This ability optimizes bandwidth resources and lowers costs, CoAdna says.

"ROADM features have shown great value in reducing both opex and capex for long-haul and metro optical networks. CoAdna's updated OVS brings those values to DCI networks." said Dr. Jim Yuan, Chairman and CEO of CoAdna. "Simplicity and low cost are two necessary characteristics of equipment for data center applications. Our team incorporates those great features in the OVS making it affordable, easy to use, and all packed in a one rack unit box. We look forward to full commercialization of this product in supporting cost-effective and environment-friendly cloud services that help make people's lives better."

CoAdna will display the updated OVS at Booth 1807 during OFC 2016 in Anaheim March 22-24, 2016.
