Polatis DirectLight Optical Switches to be Deployed Across Aurora2

By Rahul Arora October 06, 2014

Polatis, a company that provides all-optical matrix switches, recently announced that its DirectLight optical switches will be deployed across Aurora2, a new U.K. National Dark Fibre Infrastructure Service (NDFIS), funded by U.K. Engineering and Physical Science Research Council (EPSRC) and the Higher Education Funding Council for England (HEFCE). The switches, which will be deployed across the 800km Aurora2 network, and will enable researchers to reconfigure the infrastructure on demand via software defined network (SDN) control plane.

The DirectLight Optical Switches are fully non-blocking all optical matrix switches with port counts from 4x4 up to 192x192. With support of Software-Defined Networks (SDNs) via an embedded OpenFlow control interface, Polatis switches enable extremely low latency for time-critical traffic required for new virtual cloud services in hybrid packet-optical data centers. These have advanced dynamic web GUI and network management tools reduce costs and improve management.

"Future Internet applications will require a scalable and dynamically reconfigurable optical network.  Aurora2 provides an advanced software-defined optical network for the UK to pioneer new techniques for ultra-high capacity optical communications," said Nick Parsons, chief technology officer at Polatis.  "We are honoured and excited to be selected for this key initiative."

In related news, Polatis Inc. recently unveiled a hybrid packet/optical switch that can work in software-defined networking scenarios. The product, called the Series 6000 Lite 48x48, was demonstrated at the European Conference on Optical Communication in London.

The switch is unique in light of its size, low loss, back reflection and embedded OpenFlow interface, according to Polatis. A fan-free solution, its footprint is 1U. Typical loss is below1dB. Back reflection is more than 50dB. And its OpenFlow interface allows it to work in SDN environments. The company developed the switch in concert with the High Performance Networks Group at the University of Bristol, which is doing research on the extension of SDN protocols to support dynamic reconfiguration of circuit-switched optical networks.
