Infinite Capacity Engine
Innovative Optical Engines with
Record-breaking Performance
Developed by our Advanced Coherent Optical Engines and Subsystems, Infinera’s advanced optical Infinite Capacity Engines (ICE) have achieved world records in transmission, efficiency, and performance. They include the latest advances in DSPs, indium phosphide PICs, and high-speed packaging, and are a key enabling technology for Instant Bandwidth. The 1.2T, six-wavelength ICE4 introduced digital Nyquist subcarriers while achieving multiple submarine spectral efficiency records. The 1.6T, two-wavelength ICE6 has established new performance benchmarks, most recently by demonstrating 800 Gb/s single-wavelength performance over 1044.51 km in a commercial network. ICE6 Turbo further extends the performance lead of ICE by increasing the maximum baud rate from 96 Gbaud to 100 Gbaud, adding approximately 30% to 800 Gb/s wavelength reach.
ICE6: Industry-leading 800G Generation Performance over Any Network
The most advanced high-speed optical engines in the world, ICE6 and ICE6 Turbo are able to deliver record-breaking wavelength capacity-reach and spectral efficiency. Furthermore, extensive programmability, including specialized subsea modulations, enables performance to be maximized even under challenging optical conditions.
Highlights
Advanced DSPs
Infinera’s Infinite Capacity Engines are based on digital ASIC/DSPs 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 lightning 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 further 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.
