Interoute and Infinera (Nasdaq: INFN) have completed a demonstration of Infinera’s new 500 Gigabits/second (Gb/s) photonic integrated circuits (PICs) successfully delivering 100Gb/s channels on the Interoute pan-European network. Interoute, whose pan-European network was the first in Europe to deploy Infinera’s 100Gb/s photonic integrated circuits more than three years ago, is planning to use Infinera’s next generation systems based on 100Gb/s channels enabled by 500 Gb/s PICs to ensure it continues to lead the way in supporting Europe’s insatiable demand for high capacity bandwidth. Interoute’s Next Generation Network is the most advanced in Europe and Interoute is working closely with Infinera as Infinera brings to market a high-capacity solution based on coherent transmission of 100Gb/s channels.

The demonstration took place between Amsterdam and London. The 100Gb/s channels originated in Amsterdam and traveled under the North Sea to London, where they were looped back and returned to Amsterdam, for a total distance of 940 kilometers (km). The signals were received error-free despite a lengthy unrepeatered subsea link of 210 km between the Dutch and English coasts. Each 100Gb/s channel is capable of carrying over 200,000* simultaneous Video Conferences between London and Amsterdam, or over 1.5 million** telephone conversations. This is the first demonstration of Infinera’s PIC-based 100Gb/s channels transmitted on a European network.

The coherent 100Gb/s channels were transmitted on fiber simultaneously carrying 200Gb/s of live traffic over 10Gb/s channels, demonstrating that the Infinera Line System (ILS) can carry both types of optical signals without interference. Interoute is planning to introduce PIC-based 100Gb/s channels next year, to enable customers to enjoy a seamless transition to the new era of high-capacity bandwidth.

Gareth Williams, Interoute’s CEO commented “Interoute’s network is used by all the major incumbents as well as thousands of international enterprises who rely on its resilient high capacity and low latency connectivity. In the service provider market Interoute is attracting an increasing number of operators looking to outsource part or all of their European networks; innovative technologies like Infinera’s 500Gb/s PICs ensure that the network infrastructure is as advanced as Interoute’s expertise needed to support these critical projects.”

“We are encouraged that Interoute is once again leading the industry towards the next generation of network technology by choosing to deploy Infinera’s 500Gb/s PICs,” said Infinera president and CEO Tom Fallon. “We are confident that our next generation solution will once again leverage the disruptive economics of PICs, offering a system with pervasive switched DWDM capacity throughout the network, superior network economics, and the ability for the end-customer to get any service deployed anywhere in the network with unbeatable speed of service delivery.”

Infinera’s new 500Gb/s PICs each integrate five 100G channels. With Infinera’s FlexCoherent™ technology, the network operator can select the optimal modulation format to use for each route on the network. In this demonstration, the 100Gb/s channels were transmitted using PM-QPSK modulation and coherent detection to optimize for optical reach. Infinera’s 500G PIC receivers use integrated local oscillators to enable coherent detection of the signals. The pair of 500G PICs integrates more than 600 optical devices, a tenfold increase from today’s 100Gb/s PICs which are widely deployed in long-haul and metro networks worldwide.
