ZTE Corporation (0763.HK / 000063.SZ), a major international provider of 
telecommunications, enterprise and consumer technology solutions for the Mobile 
Internet, today has deployed the industry's first commercial trial of 400G OTN 
cluster system together with the Shenzhen Branch of China Telecom. 

The system supports a maximum of 64-wavelength 400G, and its capacity is 3.2 
times of that of a 100G system. It can effectively satisfy the requirements for 
cross-ring non-blocking scheduling of an enterprise private line, reduce the 
difficulty of network O&M, and help with the high-speed and stable operation of 
5G transport networks.

ZTE and the Shenzhen Branch of China Telecom deployed the industry's first 400G 
OTN cluster solution at multiple super-core nodes in the network, with each 
site supporting 128 service slots and 64T cross-connect capacity. 

Meanwhile, the solution satisfies the non-blocking scheduling requirements of a 
large number of small-granularity services brought by SDH equipment phasing 
out, effectively enabling high-speed transport of 5G, gigabit broadband and 
enterprise private line services, significantly reducing O&M difficulty and 
saving network O&M costs for customers.

Moreover, ZTE's flagship OTN device ZXONE 9700 is deployed for this solution, 
on which CE band is employed. The device supports a maximum network capacity of 
25.6T, which is 3.2 times the capacity of a 100G system, thereby fulfilling the 
demands of further network expansion and saving customer prior investment. 

In addition, the project is also deployed with a 32-degree ROADM optical-layer 
architecture, in a bid to further improve transport efficiency. The 
architecture allows MAN flatness and full-Mesh multi-directional connections, 
and supports one-hop transmission, thus decreasing OTN service transport 
latency, improving user experience and alleviating bandwidth pressure on MAN 
core nodes.

ZTE's ZXONE 9700 series has maintained the "Leader" rating in the "Core Packet 
– Optical Transport" and "Metro Packet – Optical Transport" fields, according 
to the latest assessment of GlobalData. 

By means of profound technical experience and solid market position in optical 
networking field, ZTE has deployed more than 400 100G/B100G networks across the 
world with the total fiber length exceeding 400,000 km. 

According to the latest report of Dell'Oro Group released in March 2020, the 
market share of ZTE optical network devices increased by 2.4% in 2019, becoming 
one of the two vendors with the largest increase. Moreover, Omdia showed that 
ZTE ranked No.2 in global OTN switching market in 2019. 

ZTE is a provider of advanced telecommunications systems, mobile devices and 
enterprise technology solutions to consumers, operators, companies and public 
sector customers. As a part of ZTE's strategy, the company is committed to 
providing customers with integrated E2E innovations to deliver excellence and 
value as the telecommunications and information technology sectors converge. 
Listed in the stock exchanges of Hong Kong and Shenzhen (H share stock code: 
0763.HK / A share stock code: 000063.SZ), ZTE sells its products and services 
in more than 160 countries.

To date, ZTE has obtained 46 commercial 5G contracts in major markets, such as 
Europe, Asia Pacific, Middle East and Africa (MEA). ZTE commits 10 percent of 
its annual revenues to research and development and takes leadership roles in 
international standard-setting organizations.
