Infinera is driving optical leadership with next-generation coherent technologies by increasing the capacity and reach of subsea and terrestrial systems. Infinera’s Advanced Coherent Toolkit (ACT) enables operators to improve their fiber capacity-reach performance.
Infinera combines large-scale photonic integrated circuit(PIC)-based photonics and advanced application-specific integrated circuit (ASIC)/digital signal processor (DSP) electronics, two key technologies that enable the Advanced Coherent Toolkit. Infinera’s FlexCoherent® ASIC/DSPs are based on cutting-edge electronics to deliver enhanced coherent processing with low power.
Infinera’s next-generation coherent super-channel optical performance has already been proven to be industry-leading, as validated by a spectral efficiency record 50 percent higher than alternatives on the 10,000-kilometer (km) Seabras-1 cable. Other examples of outstanding performance include submarine deployments such as Telstra International’s 4,200-km AAG5 submarine cable from Hawaii to California, terrestrial deployments such as Facebook’s “World’s Longest Terrestrial Multi-Terabit Route” and lab trials that achieve trans-Atlantic reach using advanced modulation such as polarization-multiplexed 8 quadrature amplitude modulation (PM-8QAM).
Infinera continues to pioneer the next generation of coherent technology and enables operators to harness the maximum capacity for a given reach from new or existing subsea and long-haul terrestrial cable systems carrying super-channels.
