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.


ICE6: Industry Leading 800G
The most advanced high speed optical engine in the world, recently achieved 800G single-wavelength transmission over 950 km across a major North American network operator’s live production network.
Highlights

Advanced DSPs
Infinera’s Infinite Capacity Engines leverage DSPs and ASICs designed in-house that leverage the latest CMOS process mode. Both the ICE4 and ICE6 DSPs are dual wavelength, which enables load-sharing and SD-FEC gain sharing.

Photonic Integration
Infinera’s ICE engines feature PICs designed and manufactured in-house. High-performance indium phosphide allows a wide range of optical functions to be integrated, which reduces cost, footprint, and power consumption while improving reliability.

Innovative Features
Leverage sliceable super-channels, a patented lighting mode, subsea-optimized modulation formats, the industry’s first Nyquist subcarriers, SD-FEC gain sharing, an ultra-high baud rate, long-codeword probabilistic constellation shaping, and dynamic bandwidth allocation.

Spectral Efficiency
ICE4 features like Nyquist subcarriers, super-channels, and a shared wavelength locker have enabled multiple transoceanic spectral efficiency records. ICE6 leverages long-codeword PCS-64QAM to deliver industry-leading spectral efficiency.

ICE4: Spectral Efficiency and Instant Bandwidth
Our vertically integrated 1.2 Tb/s optical engine offers six wavelengths ranging from 50 to 200 Gb/s and advanced features including Nyquist subcarriers and SD-FEC gain sharing.
