Infinite Capacity Engine

Innovative Optical Engines with
Record-breaking Performance

Developed by our Optical Innovation Center, 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.

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.
