That bank-breaking 150/35Mbps FiOS connection you're so proud to call your own? Yeah, it looks like dial-up next to the searing terabit speeds recently achieved by ZTE's optical network. The Chinese telco, mostly known stateside for its mobile handsets, has successfully completed an experiment designed to highlight the possibility of migrating "from a 100G transmission system to a 200G system." In layman's terms, that's a data punch of 200Gbps-plus sent over eight channels, which in this case, totals about 1.7Tbps. Impressed? You should be, but don't cast your home connection the side-eye just yet. Like Deutsche Telekom's comparatively lesser feat, you'll likely amass a few wrinkles and lbs before this tech becomes consumer-ready. Check out the official PR after the break.

Experiment proves seamless upgrade to 200G possible


15 March 2012, 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 and network solutions, announced it has conducted an industry first field demonstration of a 8x216.4Gb/s WDM transmission through a 50GHz optical spectrum grid.

The demonstration utilized patented ZTE high-frequency technology to accomplish a 200Gb/s polarization multiplexing QPSK signal transmission at 50GHz through 1,750km of standard single model fiber optic cable. This resulted in a 25 per cent increase in spectrum efficiency and an increase in transmission efficiency. The experiment proves a seamless upgrade from a 100G transmission system to a 200G system is possible. A record of the demonstration was presented at the OFC/NFOEC 2012 conference.

ZTE is committed to 100G and beyond-100G research. The company was the first in the world to successfully complete a single-channel 11.2Tbit/s optical signal transmission experiment.

ZTE is also an industry leader in next-generation bearer network solutions and high-speed optical communications transmission technology. As such, it was the first company to release whole-course 100G solutions in 2010. The company has completed several trial network projects in the 100G and beyond-100G fields with the mainstream operators from China, Germany, Russia and the United States.
