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

Telecom equipment vendor ZTE on Monday said the company — in collaboration with China Telecom Beijing Research Institute — set a world record in real-time terabit optical transmission.

Utilizing ZTE’s ZXONE 8700 platform, China Telecom deployed a terabit Wavelength-division multiplexing (WDM) real-time transmission system.

Both Chinese companies completed real-time data transmission over a distance of 3,200 kilometers on G.652 optical fiber without Raman amplification that was error-free for 24 hours, achieving a world record, said ZTE in a statement.

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, which ranked second in market share in the optical transport network product segment, said 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 2012, ZTE and Deutsche Telekom completed 100G/400G/1T long-haul transmission over 2,450 kilometers, setting a record in long-distance multi-rate mixed transmission. ZTE has 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.
