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
