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
