Huawei Proposes Optical Slicing as the Cornerstone for Next-Generation Optical Transport Networks

SHENZHEN, China, March 25, 2021 /PRNewswire=KYODO JBN/ --
Richard Jin, President of Huawei's Transmission and Access Product Line,
delivered a keynote speech themed "Intelligent Connectivity: the Digital Artery
of Industry Intelligent Twins" at the Huawei Industrial Digital Transformation
Conference. More importantly, this is the first time Huawei has proposed
optical slicing as the cornerstone of the next-generation optical transport
network. Huawei Liquid OTN-based optical slicing guarantees a deterministic
service experience and supports the long-term evolution of industrial
transformation, making it ideal for SDH upgrading in power grid and
transportation industries.
As services diversify in the power grid and transportation industries, digital
upgrades demand higher bandwidth, lower latency, and greater reliability from
network solutions and innovative technologies. Richard said: "Optical network
is the most deterministic communication mode. Industries with high
deterministic requirements, such as power grid and transportation, generally
use traditional SDH technology with multi-levels mapping and limited speed.
Therefore, it cannot meet the differentiated service requirements of digital
transformation. In contrast, optical slicing technology based on Liquid OTN,
provides intelligent connectivity and is a much better choice."
Today's world is experiencing explosive data growth, but such data is only
valuable when it flows. To ensure efficient data transmission, optical
transport networks are needed to build stable and reliable ICT infrastructures,
of which China has the world's longest and highest capacity ultra-high voltage
direct current (UHVDC) system. This system comprises many digital devices that
generate massive data every day, which needs to be carried securely to control
centers. With optical slicing, the huge bandwidth of optical fibers are divided
into different isolated slices and services enjoy exclusive channels. This
eliminates interference and network congestion, delivering differentiated and
deterministic bandwidth for services.
Huawei has been leading the evolution of optical transport technologies for the
last two decades. Liquid OTN is crucial to promoting the commercialization of
optical slicing as it inherits physical isolation from SDH and achieves two
innovations:
First, it introduces the OSU encapsulation technology to merge 3 layers into 2,
and compared with SDH, it cuts device latency by 30%.
Second, it features a converged architecture, combining the SDH and OTN
technologies to provide small-granularity slices and ultra-broadband. The size
of a slice can be adjusted on demand in real time from 2 Mbit/s to 100 Gbit/s
without impacting services.
Currently, Huawei OptiXtrans E6600, which is the industry's first optical
transport platform with Liquid OTN optical slicing technology, has been widely
used in the energy, transportation, finance, education, and government sectors.
Huawei OptiXtrans E6600 will support services bearing on Ethernet ports on the
power grid and transportation production networks, which provides a true
deterministic experience based on physical isolation. Huawei will continue to
innovate Liquid OTN-based optical slicing technologies, and lead intelligent
connections into a deterministic era.
From March 24 to 26, Huawei hosts the Industrial Digital Transformation
Conference 2021, which will be webcast globally. For more details, please visit
