400Gbps signaling completed over distance in excess of 5,000km;

　　　　　　　　　　　　　　  capacity of ZTE’s system is double that of most advanced systems currently available in industry

7 June 2013, Shenzhen, China – ZTE Corporation (“ZTE”) (H share stock code: 0763.HK / A share stock code: 000063.SZ), a publicly-listed global provider of telecommunications equipment, network solutions and mobile devices, completed data signaling at speeds of 400 Gigabits per second over a distance of more than 5,000km, setting a benchmark for the global optical networking industry.

The industry-first data transmission was achieved on a WDM system with 100Ghz channel spacing. Data was transmitted through 25 ROADM nodes without electrical repeater. The communications capacity of ZTE’s system is double that of the most advanced systems currently available in the industry.

ZTE used a unique frequency algorithm to overcome the issue of signal degradation, a common industry challenge in wideband communications over long-distance. The success of this transmission laid technical foundation for further development of global high-speed broadband networks.

With the growth of global broadband services, high bandwidth transmissions have become a basic requirement of communication networks. The long-distance transmission capability of a high-speed signal is a key component in the development speed of communications and services on a network. Because of this, 100G and 400G technologies are becoming key components of the world’s telecommunications industry infrastructure.

ZTE has long been dedicated to research of 100G and 400G/1T high-speed transmission solutions for many years. Its research has resulted in a variety of products, and applications. In February 2011, ZTE became the world’s first company to transmit a single-channel 11.2Tbit/s optical signal. It also completed a 641-km transmission at 1Tb/s in standard single-mode fiber, a new world record at the time. In July 2011, ZTE became the first in the industry to complete a 24Tb/s (24*1.3Tb/s) WDM signal transmission.

In February 2012, ZTE and Deutsche Telekom successfully completed a 2,450-km long-distance hybrid transmission of 100G/400G/1T signal in Germany. ZTE also used its patented technology to implement what was then a world-record 2,800-km long--haul 400G transmission without electrical repeater in September 2012.

According to the latest market analysis report “Market share-1Q13 Global ON” released by Ovum, ZTE displaced Alcatel-Lucent to take second position in the optical network market. ZTE also ranks No.1 globally in aggregation market, and No. 2 in CPO-T (Converged Packet Optical Transport) market. ZTE has rich accumulation in 100G technology. The company has successfully deployed over 30 100G trial networks and commercial networks around the world.
