ICE4 Optical Engine
Maximize Spectral Efficiency and Enable Instant Bandwidth
Infinera’s fourth-generation Infinite Capacity Engine (ICE4) delivers 1.2 Tb/s of optical transmission capacity via six individually programmable wavelengths at up to 200 Gb/s each. With the introduction of digital Nyquist subcarriers, ICE4 has achieved industry-leading spectral efficiency and performance, including on the 6,644-km MAREA trans-Atlantic submarine cable. Supported in the XTC, XT, and CX Series platforms, ICE4 delivers capacity when and where service providers need it. Combined with Instant Bandwidth, ICE4 enables unprecedented flexibility to add and reallocate bandwidth with the click of a mouse.
Maximum Fiber Capacity
Nyquist subcarriers, a shared wavelength locker, and super-channels enable ICE4 to deliver 27.6 Tb/s in the C-band with spectral efficiency of 5.75 bits/s/Hz. ICE4 has set both trans-Pacific and trans-Atlantic spectral efficiency records. An L-band version of ICE4 enables more than 50 Tb/s per fiber pair (C+L).
Instant Bandwidth Enablement
Adapt to changing traffic demands with the ability to quickly add, move, and retire bandwidth by leveraging the six programmable wavelengths of ICE4 and Infinera’s Instant Bandwidth application.
Extreme Lightning Tolerance
Leveraging Nyquist subcarrier technology, ICE4 provides a patented lightning mode that protects against all known/observed lighting strikes with industry-leading state-of-polarization tolerance.
Flexible Deployment Options
ICE4 can be transported over both fixed grid and flexible grid networks. In addition to Infinera line systems like FlexILS, ICE4 can be deployed over open line systems and legacy DWDM line systems from third parties (Open ICE).
