Cost Effective Distance Extension and MediaCost Effective Distance Extension and Media Conversion Solutions for 100G Connectivity

PacketLight Networks and Arista Networks have jointly developed and tested a set of solutions that leverage Arista’s market-leading 100GbE port density and PacketLight’s multi-rate multi-protocol muxponder/transponder and 100G Transponder, to create cost-effective and scalable distance extension and media conversion solutions.

Arista Networks switches deliver 100GbE connectivity with industry-leading density of up to 96 ports in a single system that addresses a wide variety of datacenter deployments using embedded short reach optics. Scenarios that call for long distance 100GbE connectivity often require the deployment of costly DWDM transport systems and switch or router ports that support longer reach single mode optics. Existing 100GbE single mode switch optics (CFP or CXP) reduce system density, dramatically increase equipment cost and reduce the scalability of the network.

Deploying PacketLight solutions enables to either interconnect two sites at distances outside the range of embedded multimode optics, or to offer a single mode presentation to longer reach infrastructure on a port-by-port basis, and provides a cheaper alternative to using expensive upstream device ports for media conversion.
