Infinite Capacity Engine

Innovative Optical Engines with
Record-breaking Performance

Developed by our Optical Innovation Center, Infinera’s advanced optical engines have achieved world records in transmission, efficiency, and performance. Our Infinite Capacity Engines (ICE) include the latest advances in digital signal processors (DSPs), indium phosphide photonic integrated circuits (PICs), and high-speed packaging. The 1.2T, six-wavelength ICE4 introduced the world to digital Nyquist subcarriers while achieving multiple submarine spectral efficiency records. The 1.6T, two-wavelength ICE6 has established a new performance benchmark by demonstrating 800 Gb/s single-wavelength performance over 950 km in live field trials.

With deep vertical integration and extensive programmability, our optical engines form the basis for Instant Bandwidth, enabling incremental capacity and service activation with the click of a mouse, dramatically simplifying operations, accelerating time to revenue, and eliminating many of the challenges associated with network planning and forecasting.
