Infinera is the leader in large-scale photonic integrated circuits (PICs), having pioneered the use of PIC-based super-channels in Optical Transport Network (OTN) platforms since 2005 when it introduced the world’s first large-scale PIC. This first-generation PIC transformed the 10 gigabits per second (10G) transport market, delivering a step function in network bandwidth economics by combining over 60 different functions into a fingernail-sized pair of chips while provisioning 100G of capacity in one operational cycle. In 2009, the second-generation PIC was introduced, dramatically improving optical network performance to support ultra-long-haul terrestrial and subsea applications.
The subsequent step function in transport performance was delivered in 2011 with the introduction of the 500G PIC and the FlexCoherent® digital signal processor (DSP)/application-specific integrated circuit (ASIC) as key elements of the Infinera DTN-X platform. This was the third generation of Infineras’s PIC technology, with five 100G channels, effectively delivering a 500G super-channel.
Today, Infinera’s Infinite Capacity Engine delivers the next step function in optical transport with the industry’s first multi-terabit opto-electronic subsystem. The Infinera Infinite Capacity Engine is powered by the advanced electronics in the next-generation FlexCoherent Processor and the cutting-edge photonics of Infinera’s fourth-generation PIC. The Infinera Infinite Capacity Engine is the first in the industry to offer network operators the combined benefits of optical super-channel capacity up to 2.4 terabits per second (2.4T) and reach greater than 12,000 kilometers (km) in one of the world’s smallest optical subsystems, with very low power consumption.
The engine provides sliceable photonics to tune and route any 100G wavelength within a super-channel or Nx100G super-channels in multiple separate directions, each with its own coherent modulation profile. Sliceable super-channels provide massive scalability with fine-grained granularity, delivering tremendous flexibility.
