The 8-port 200G coherent DWDM line card delivers full 1600G of bandwidth. The Arista 100G/200G DWDM solution is integrated to a 7500R Series line card offering high-density with un-compromised performance at an efficient cost point. It utilizes state of the art coherent optical technology to enable simple, reliable and scalable data center interconnect solutions for both metro and long haul applications with flexible support for 100G, 150G and 200G modes.

The phenomenal growth in demand for bandwidth, driven by mobile, video streaming and cloud applications, is driving the need for connecting several geographically dispersed data centers to maintain seamless content delivery and provide application agility. Cost effective high bandwidth data center interconnect can help organizations to meet several business objectives including business continuity and disaster recovery, large scale data transfer for analytics, big data, cluster computing and for scalability of metro data center topologies.

For organizations that own or rent dark fiber, high bandwidth data center interconnect (DCI) based on coherent technology offers significant CapEx and OpEx benefits. An open and programmable DCI solution, like the Arista DWDM line card, decouples the optical interface from the line system components (multiplexers, amplifiers, ROADMs) and can be integrated with existing legacy line systems or any widely available open line system reducing the overall upgrade cost.
