ICE6 800G Generation Optical Engine
Windstream Partners with Infinera to Transmit 800G over 730 Km in Live Production Network Using ICE6 Technology
In addition to the industry-leading real-world performance at 800G, Windstream and Infinera set another industry record by looping back the signal to achieve a 700G transmission over 1,460 km.
The Ultimate Guide to Nyquist Subcarriers
Coherent optical transmission has delivered a dramatic enhancement in the capacity-reach product for long-haul and subsea cables. The first wave of coherent systems located all of the digital processing power in the receiver. Today, a second wave of coherent systems has both transmitter- and receiver-based processing, and can deliver around 30 times the capacity of noncoherent technology.

Minimize Optical TCO with 800G
The sixth-generation Infinite Capacity Engine (ICE6), the latest innovation from Infinera’s Optical Innovation Center, is a 1.6 Tb/s optical engine that delivers two independently programmable wavelengths at up to 800 Gb/s each. ICE6 utilizes second-generation digital Nyquist subcarriers, advanced PIC technology, and 7-nm DSP silicon geometry to break performance and spectral efficiency barriers, including 800G single-wavelength performance over 950 km in a live field trial. While 800G is the headline rate, ICE6 is also shattering optical transmission expectations for 600 Gb/s and 400 Gb/s per wavelength.
ICE6 enables network operators to meet the demands of rapid bandwidth growth by providing the greatest capacity at the greatest reach, resulting in a solution with the lowest cost and power per bit and the highest spectral efficiency possible. With Instant Bandwidth, ICE6 extends service providers’ ability to rapidly increase, move, and retire transmission capacity when and where they need it.
With a state-of-the-art maximum baud rate of 96 Gbaud, ICE6 delivers industry-leading wavelength capacity-reach over a wide range of wavelength speeds, including 800G, 600G, and 400G. Proof points include a recent live network trial of 800G over 950 km.
Maximize Fiber Capacity
Spectral efficiency of 8.833 bits/s/Hz and total C-band capacity of 42.4 Tb/s can be achieved with 800G wavelengths, with C+L band enabling more than 80 Tb/s. Key enabling features for maximizing spectral efficiency over longer distances include Nyquist subcarriers, a shared wavelocker, long-codeword probabilistic constellation shaping (64QAM), dynamic bandwidth allocation, and SD-FEC gain sharing.
Lower Operational Costs
ICE6 enables platform power consumption of less than 0.2 W/Gb/s and can deliver up to 3.2 Tb/s of coherent bandwidth in one rack unit. Operational costs are further reduced with a small number of high-capacity wavelengths to provision and manage, as opposed to a larger number of lower-capacity wavelengths.
Leverage Innovative Features
Innovative features include second-generation Nyquist subcarriers, long-codeword probabilistic constellation shaping, dynamic bandwidth allocation, and SD-FEC gain sharing. Additional advanced features include high-performance FEC, advanced telemetry, wire-speed encryption, and the ability to load-balance clients. over the two wavelengths.
