ZTE, China Telecom set world record in real-time terabit optical transmission

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, is pleased to announce that the company set a world record in real-time terabit optical transmission in collaboration with China Telecom Corporation Beijing Research Institute.

Deploying a terabit wavelength-division multiplexing (WDM) real-time transmission system based on ZTE's ZXONE 8700 platform, ZTE and China Telecom completed real-time data transmission over a distance of 3 200 kilometres on G.652 optical fibre without Raman amplification that was error-free for 24 hours, achieving a world record. The real-time nature of the successful test by ZTE and China Telecom marked a major advance from past experiments that were based on offline systems.

ZTE and China Telecom built the fastest and longest-distance real-time optical transport system by using advanced Nyquist WDM Terabit PM-QPSK optical modulation and optical coherent detection technologies, in addition to ultra-high-speed signal processing and soft-decision forward error correction algorithms, achieving spectral efficiency of 4bit/Hz/s.

The latest advance by ZTE further strengthened the company's global leadership in terabit optical transport systems. As demand for bandwidth explodes globally, research into data transport systems capable of support data transmission of over 100 Gigabits per second is becoming a priority for operators and technology vendors globally. Long-haul transmission capability and spectral efficiency are two of the biggest hurdles that must be overcome to drive the successful deployment of Beyond 100G systems. ZTE's industry leadership in long-haul and high-speed optical transport systems will help operators sustainably increase the bandwidth of their networks, and reduce the total cost of ownership.

In 2012, ZTE and Deutsche Telekom successfully completed 100G/400G/1T long-haul transmission over 2 450 kilometres, setting a record in long-distance, multi-rate mixed transmission. ZTE has successfully deployed more than 50 100G trial and commercial networks globally.

ZTE posted record revenue in optical network products in the second quarter of 2013, achieving the industry's fastest growth rate in the preceding 12-month period, according to data from research company Ovum. ZTE was the world's number two vendor in optical network products, scoring a higher ranking than vendors including Alcatel Lucent. ZTE also ranked second in market share in the optical transport network product segment.
