Infinera Sets Two Industry-First Milestones for Optical Transport Technologies
October 19 2017 - 4:30PM
Infinera, the leading provider of Intelligent Transport Networks,
achieved two industry-first milestones for advanced coherent
technologies that increase the capacity and reach of optical
transport networks to the next level. The first milestone drives
optical transmission technologies to 100 gigabaud (GBaud), and the
second milestone enhances modulation technology to 1024QAM
(quadrature amplitude modulation). These new technologies are
designed to deliver the highest possible capacity on a single
wavelength for varied distances, helping operators extract the best
performance from their optical transport networks.
“Infinera uniquely uses vertical optical integration to extract
maximum performance from the optical transport network,” said
Andrew Schmitt, Lead Analyst at Cignal AI. “The new levels of
performance in baud rate and modulation schemes for terabit
wavelengths exhibited at ECOC are a good example of how this
approach can eventually result in production solutions with greater
capacity and reach.”
Optical transport networks are a critical component of the
global communications infrastructure, enabling cloud-based services
to reach users around the world, and rely on three axes for
increasing transmission performance:
- Baud rate: The rate at which modulation
symbols are sent. The typical deployed baud rate is 32 GBaud with
the quadrature phase shift keying modulation carrying 4 bits per
baud, resulting in 100 gigabits per second of transmission. While
industry opto-electronics are moving to 66 GBaud development
demonstrations, Infinera is the first to showcase 100 GBaud using
32QAM to achieve a single-wavelength 1 terabit per second (Tb/s)
data rate using multi-channel indium phosphide-based photonic
integrated circuits (PICs) integrated with electronic driver and
amplifier application-specific integrated circuits. This result was
presented at the 2017 European Conference on Optical Communications
(ECOC).
- Modulation scheme: Converts the bits to
symbols. At ECOC, Infinera showcased the higher-order modulation
scheme of 1024QAM using advanced constellation shaping algorithms
and Nyquist subcarriers, allowing wavelengths to be spaced close to
each other to maximize the data rate for a certain reach. The
Infinera test bed used 66 GBaud at 1024QAM to reach 1.32 Tb/s,
yielding spectral efficiency of 9.35 bits per second per hertz over
400 kilometers (km), an industry first.
- Channel count: Implements multiple parallel
wavelengths on a single module to create a coherent super-channel.
As baud rates increase, placing optical components closer together
on an integrated chip reduces component size and power while
increasing reliability.
Baud rate and modulation scheme have been addressed by the
industry for some time, with Infinera now setting new milestones
for each. Infinera’s PIC technology uniquely enables
high-channel-count coherent super-channels. These innovative
technologies indicate the next level of capacity and reach
achievable in the years to come.
“Infinera is delivering optical engines at a faster cadence to
help operators achieve exceptional capacity and reach performance
on their transport network infrastructures,” said Dr. Dave Welch,
Infinera Co-Founder and President. “As 5G wireless and cable video
services take off, Infinera offers significant value to transport
network operators by designing industry-first solutions.”
