Infinera's optical networking Infinite Capacity Engine aims at multi-terabit systems

March 22, 2016 // By Graham Prophet
Infinera, provider of Intelligent Transport Networks, has announced the Infinite Capacity Engine, a multi-terabit optical subsystem enabling a step function in optical wave division multiplexing (WDM) performance.

Infinera says it is the first optical subsystem to offer network operators the combined benefits of delivering optical super-channel capacity up to 2.4 terabits per second (Tb/s) and reach up to 12,000 kilometers, in a single small package.


The Infinite Capacity Engine uses Infinera's next generation FlexCoherent Processor and the company's fourth generation photonics integrated circuit (PIC). The Infinite Capacity Engine will be integrated into Infinera Intelligent Transport Network platforms for long-haul terrestrial, subsea, metro and data center interconnect networks .


Enabling a step function in optical networking performance, the Infinite Capacity Engine is designed to deliver 2.4 Tb/s of optical bandwidth and long reach in the smallest subsystem. It consumes relatively little power – 82% less power per gigabits per second (Gb/s) than the nearest competitor.


Massive scale: Infinera’s Infinite Capacity Engine enables massive network scale supporting super-channels up to 2.4 Tb/s from a single subsystem with up to 12 times more bandwidth than other implementations.

Advanced Coherent Toolkit (ACT): The Infinite Capacity Engine delivers up to 60% more capacity-reach performance for submarine and terrestrial networks than the current generation of optical technologies by allowing extended reach and/or utilisation of higher order modulation formats on a per channel or super-channel basis in challenging fibre environments. The Infinera ACT features Nyquist subcarriers, a technology that increases tolerance for non-linear effects and SD-FEC gain sharing. In addition, multiple modulation formats are supported including matrix enhanced – phase shift keying (ME-PSK), BPSK, 3QAM, QPSK, 8QAM and 16QAM.

Sliceable super-channels: The Infinite Capacity Engine provides the ability to deliver 2.4 Tb/s of capacity in a single module with a single fibre pair. In addition, it provides fine-grained and flexible control of optical wavelengths at 100 Gb/s. The Infinite Capacity Engine can tune and route a 100 Gb/s wavelength or N x 100 Gb/s super-channels in multiple separate directions with any specified flexible grid coherent modulation across the extended C-Band.
