Network, expanding the original vision as service providers and internet content providers prepare for the Terabit Era.
The Intelligent Transport Network enables carriers to create rich end-user experiences based on efficient, high-capacity transport by combining the following elements:
Scalability:
The proliferation of data centres, rise of big data and increasing consumption of video are fundamentally changing traffic characteristics in operator networks. The Intelligent Transport Network delivers 500 Gb/s FlexCoherent super-channels today and is designed to scale without compromise to enable terabit super- channels and Terabit Ethernet in the future.
Convergence:
Networks are growing in complexity with the proliferation of chassis, network layers and fibre interconnects. Complexity increases the time it takes to plan and deploy network services and ncreases the cost of maintenance, operations, power, space and cooling.
By converging packet, OTN and reconfigurable optical add-drop multiplexer (ROADM) switching functions the Intelligent Transport Network is designed to reduce complexity while lowering overall network spending without compromising performance.
Automation:
Network operators face intensifying competition to meet customer demand for immediate bandwidth needs and better visibility into the network. The Intelligent Transport Network features intelligent software control to help simplify multi-layer provisioning, and in the future will support Transport Softw are Defined Network (SDN). Automation allows end-user control of their ownnetwork services and aligns service revenue to transport network growth through capabilities such as Infinera Instant Bandwidth.
“We believe Infinera delivers the world’s most innovative networking solutions, helping our customers win in the marketplace by enabling an infinite pool of intelligent bandwidth,” says Dave Welch, Infinera EVP and Chief Strategy Officer. “The Intelligent Transport Network takes the Digital Optical Network to the next level with automated controyl, converged multi-layer switching and scalable super-channel transmission. Unlike the competition, we are not retrofitting legacy 10G and 40G platforms. We have designed the Intelligent Transport Network from the ground up for the Terabit Era.”
MDS 2-D electronics leaps forward
Researchers in the US have advanced molybdenum disulphide (MoS2) technology. This semiconductor could be joined with graphene and hexagonal boron nitride to form FETs, integrated logic circuits, photodetectors and flexible optoelectronics
Scientists at Rice University and Oak Ridge National Laboratory (ORNL) have advanced on the goal of two- dimensional electronics.
They have developed a process to control the growth of uniform atomic layers of molybdenum disulphide (MDS).
Similar to silicon, MDS is an indirect band gap semiconductor. It is one of a trilogy of materials needed to make functioning 2-D electronic components. They may someday be the basis for the manufacture of devices so small they would be invisible to the naked eye.
The work undertaken by the scientists appears online this week in the journal Nature Materials.
The Rice labs of lead investigators Jun Lou, Pulickel Ajayan and Boris Yakobson, collaborated with Wigner Fellow Wu Zhou and staff scientist Juan-Carlos Idrobo at ORNL in an initiative that incorporated experimental and theoretical work.
The goals were to see if large, high-quality, atomically thin MDS sheets could be grown in a chemical vapour deposition (CVD) furnace and to analyse their

“Our Stockholm to Hamburg route is an important network for us, one of the busiest in delivering services to our end users in the Nordic region,” adds Erik Hallberg, President of TeliaSonera International Carrier. “Our experience with the Infinera Intelligent Transport Network in North America gave us a competitive edge by enabling us to use time as a weapon to deliver 10 GbE and 100 GbE services faster than the competition. We look forward to expanding our Intelligent Transport Network into Europe with Infinera.”
“Infonetics surveyed service providers and found almost 90 percent of them plan to deploy platforms that converge OTN switching and WDM transmission by 2016,” concludes Andrew Schmitt, Principal Analyst, Optical at Infonetics Research. “The approach Infinera is taking with the Intelligent Transport Network aligns with what the largest global carriers are looking for,” concludes Schmitt.
