ZTE, China Telecom send 1 Tbps 3200 km

Oct. 29, 2013
ZTE Corp. (H share stock code: 0763.HK / A share stock code: 000063.SZ) says it collaborated with China Telecom Corporation Ltd. Beijing Research Institute to send a 1-Tbps signal 3200 km.

ZTE Corp. (H share stock code: 0763.HK / A share stock code: 000063.SZ) says it collaborated with China Telecom Corporation Ltd. Beijing Research Institute to send a 1-Tbps signal 3200 km.

The demonstration used a terabit WDM real-time transmission system based on ZTE’s ZXONE 8700 platform. The optical transmission occurred over G.652 optical fiber without Raman amplification, ZTE says. The fact that the collaborators maintained this transmission error-free for 24 hours means they set a world record, ZTE says.

The optical transport system used Nyquist WDM terabit PM-QPSK optical modulation and optical coherent detection technologies, as well as ultra-high-speed signal processing and soft-decision forward error correction algorithms to achieve spectral efficiency of 4 bit/Hz/s, ZTE says.

This is the second major 1-Tbps transmission demonstration ZTE has announced. The company partnered with Deutsche Telekom in early 2012 on a 100G/400G/1T long-haul transmission test over 2450 km. It demonstrated a prototype 400G/1T system later that year (see “ZTE displays 400-Gbps and 1-Tbps DWDM prototype”).
