Nokia pushes optical network capacity to theoretical limits
with Photonic Service Engine 3 chipset; massive scale and radical
simplicity for video, cloud and 5G growth
- First chipset to implement probabilistic constellation shaping
(PCS), a technique pioneered by Nokia Bell Labs that pushes
fiber-optic performance close to the Shannon limit
- Enables maximum capacity over any distance and on any fiber -
from metro to subsea - increasing capacity up to 65% over currently
deployed networks while reducing power by 60%
- Reduces complexity and dramatically simplifies network
operations
- Increases financial return and longevity of expensive optical
fibers by using latent capacity
- Ideally suited to meet surging traffic demands of video, cloud
and 5G for webscale companies and communication service
providers
06 March 2018
Espoo, Finland - Nokia today announced the next generation of
its Photonic Service Engine (PSE) family of super-coherent digital
signal processors, underscoring its leading position in the
industry and innovation pedigree. The Nokia PSE-3 will be
instrumental in the evolution of communication service provider
(CSP) and webscale networks to meet the surging traffic demands of
video, cloud and 5G by maximizing the capacity and performance of
every link in their optical networks.
The PSE-3 chipset is the first coherent digital signal processor
to implement probabilistic constellation shaping (PCS), a
modulation technique pioneered by Nokia Bell Labs. PCS pushes
optical fiber transmission capacity to very near the Shannon Limit
- the maximum theoretical capacity of a communications channel,
defined by Claude Shannon in 1948 while a researcher at Bell
Labs.
By intelligently shaping the signal to match the characteristics
of the optical fiber, PCS generates wavelengths that are more
resilient to noise and other impairments, increasing capacity up to
65 percent over currently deployed networks, while also reducing
power per bit by 60 percent. Networks built with systems using the
new chipset require up to 35 percent fewer optical transponders,
and by recovering latent capacity in deployed fiber, the PSE-3
extends the life of existing line systems and subsea cables,
resulting in significant long-term savings.
The chipset not only maximizes performance, but does so at any
possible distance within an optical network - from metro to
subsea. The PSE-3 is ideal for CSPs and webscale companies
looking to push the limits of their optical networks and increase
their return on expensive fibers.
With its extremely powerful yet simple programmability, the
PSE-3 presents an ideal opportunity for network operators to grow
beyond the limited flexibility of the 100G/200G networks that are
prevalent today, to a highly scalable and automation-ready network.
Reversing the tide of ever-increasing complexity in Wavelength
Division Multiplexing (WDM) systems, the PSE-3 provides finely
adjustable wavelength capacity from 100G to 600G with a single,
uniform modulation format, baud rate, and channel size. This
radically simplifies network operations and planning, while greatly
facilitating the dynamic operations that enable network operators
to deploy innovative services and lower costs.
Rajesh Singh, GM Value Management and Procurement, Spark New
Zealand, said: "Spark and Nokia have a proud partnership
delivering optical innovation in New Zealand and ensuring our
network stays ahead of market demand. Building on our 2012
introduction of 100G transport and 200G in 2017, the new Nokia Bell
Labs powered PSE-3 technology will allow Spark to plan towards 400G
and 1Tb services supporting the significant predicted traffic
demands of 5G, video, business services and IoT. We're very excited
about the world leading capability of the Nokia PSE-3 to help us
meet those demands and at the same time reducing the cost per
transported bit."
Andrew Schmitt, founder and lead analyst at Cignal AI,
said: "With the arrival of the new PSE-3, Nokia is making a
significant leap forward in the performance of high-end
coherent DSPs. PCS enables network operators to extract
maximum spectral efficiency out of their networks. This technology
also enhances all distances and applications, which makes it ideal
to address the requirements of not only cloud and colocation
operators, but also traditional incumbent and cable MSO
providers."
Sam Bucci, head of optical networks for Nokia, said "This
is a breakthrough in how we can maximize the performance of optical
networks and, at the same time, vastly simplify operations. The
Photonic Service Engine 3 is the culmination of a decade of
research and first-hand experience building the largest, highest
capacity optical networks in the world. By introducing this extreme
and yet remarkably simple programmability, our customers can now
maximize the capacity of every link in their network, whether
that's 10 km, 10,000 km or beyond. They will be able to keep
their costs under control while handling the huge bandwidth demands
that video, cloud, and soon 5G will be throwing at them."
The PSE-3 will be available across Nokia's packet-optical
portfolio, including a new version of the 1830 Photonic Service
Interconnect, a compact modular WDM platform widely adopted by
internet content providers for high capacity datacenter
interconnect. Based on a modular chassis architecture, the
1830 PSI-M will offer both cost-optimized and high-performance
modules utilizing the PSE-3, and will be available in Q3 2018.
Nokia will host an event March 13, 2:45pm in booth #2228
at the Optical Fiber Communications (OFC) Conference and Exhibition
in San Diego, California, March 13-15. Senior Nokia executives
along with Bell Labs researchers and customers will present the
inspiration and vision behind Nokia's latest innovation, and the
next chapter of the company's portfolio enhancements. The 1830
PSI-M and other Nokia optical networking products will also be
featured in the Nokia booth.
