DANTE and Infinera deliver 2 Tb/s capacity in under 12 minutes


Infinera’s indium phosphide (InP) based PICs have been activated on the GEANT production network from Amsterdam to Frankfurt


Infinera and DANTE (Delivery of Advanced Network Technology to Europe) have announced the fastest known provisioning of multi-Terabit capacity across a live network.


The firms were able to install and activate 2 Terabits per second (Tb/s) of long haul super-channel optical capacity and provision a 100 Gigabit Ethernet (GbE) service over the GÉANT production network all in less than 12 minutes from plugging in the first line card.


The demonstration was carried out using production DTN-X platforms and deployed on the GÉANT backbone, using a long distance link from Amsterdam, Holland to Frankfurt, Germany, a distance of 671km, including 10 fibre spans.


First the 2 Tb/s of line side capacity was activated and then the 100 GbE service was deployed as part of the test to show that the capacity was immediately available for service. The companies believe that rapid delivery of capacity and service is a key advantage of Infinera solutions and allows carriers to respond to customers’ rapidly changing demands.


“When Infinera was involved in the procurement process for the GÉANT backbone they made a number of claims about their ability to turn up long haul capacity very rapidly, and we decided to put those claims to the test,” says Michael Enrico, CTO of DANTE.


He continues, “The fact is that critical science experiments across Europe are generating immense quantities of data that are often difficult to fit into a forecasting process, so this ability to turn up, or redirect long haul capacity in a matter of minutes will help us transform the service we offer to our National Research and Education Network partners.”


The trial involved lighting up four 500Gb/s super- channels, and then provisioning a 100GbE service across the link. The trial was timed on a stopwatch, and a time-lapse video of the provisioning process is available here.


“This was a genuine test of our rapid provisioning capability, using real production equipment and software,” adds Geoff Bennett, Director of Solutions and


IGN1011M675


Intended for commercial avionics applications including IFF Mode S applications, the PN IGN1011M675 operates over the instantaneous bandwidth covering 1030 MHz in the L-band frequency range. Characterised with a pulse train of 2.4ms with 6.4 percent LTDC, the IGN1011M675 typically supplies a minimum of 750 watts of peak output

Technology at Infinera. “If we had used conventional 100G transponders we would need a total of 40 of them - 20 at each end. But the Infinera 500G solution allows an engineer to provision up to five times as much capacity in a single operational cycle. Enabling our customers to use time as a weapon is a key value of coherent super- channels.”


The Amsterdam-Frankfurt link was selected because this route is one of the busiest in Europe. This link is now in service with the DTN-X and carrying production traffic for the European NREN community.


Integra introduces new L-band GaN-on-SiC chips


The company has expanded its gallium nitride on silicon carbide portfolio of devices for the L-band avionics market


Integra Technologies, Inc. (ITI), a manufacturer of high- power pulsed RF transistors, has revealed two GaN on SiC technology devices targeted for the L-band market.


Integra’s RF design team has launched two new products characterised in the L-band; the IGN1011M675 and the IGN1011M1200.


“With the release of these state-of-the-art GaN products, Integra demonstrates the commitment to provide high- power pulsed L-band RF transistors for the avionics market” says Fouad Boueri, Director of Operations. “We have years of RF expertise manufacturing high power semiconductors and providing on-time delivery and top quality. Outstanding customer support continues to be our goal.”
