Huawei Achieves 2Tbit/s for 2066 Miles Through Optical Fiber

Huawei successfully tested optical fiber-based 2 Tbit/s transmissions over 2066 miles.

Last week Chinese telecoms equipment vendor Huawei said that it had successfully completed a field trial using optical fiber transmission technologies on Vodafone’s live network. The company claimed it reached 2 Tbit/s transmission capabilities over 3,325 km, or 2066.059 miles. This capacity is essentially twenty times higher than current commercially deployed 100 Gbit/s (100G) systems, Huawei said.

The field trial achieved a "record-breaking" transmission distance of 1500 km (932 miles) by using a super-channel PDM-16QAM-based high spectral efficiency solution. The company then broke another record by achieving a transmission distance of 3,325 km (2066 miles) using a super-channel Nyquist PDM-QPSK-based ultra-long-haul solution.

According to Huawei, both transmissions were on a link with G.652 fibers and erbium-doped fiber amplifiers (EDFAs) without electrical regeneration. The company added that the link used in the trial was on Vodafone's backbone network, passing through a few cities across middle and south Germany.

"We are at the forefront of global 100G deployments, and have taken the lead in delivering key breakthroughs in technologies beyond 100G. Through collaboration with Vodafone and other leading international operators and customer-centric R&D, Huawei is always ready to build advanced optical networks for customers," said Jack Wang, president of Huawei's transport network product line.

    Holy cow! That is mindbogglingly fast even for a test. I didn't think it'd be a while until Google fiber looked like small potatoes, but this about does it. The only sad part is that they aren't at the full-deployment stage yet.

    China steals tech from the US and then actually develops it....... Broadband providers need to get their greedy heads out of their **** in the US Most countries have higher speed broadband than the US and the internet started in the US.

    Solution... boycott all ISP's and demand better speeds. You'll see how fast things move up. The thing is we can't live without the internet for a week so our weakness is their ultimate gain. ISP profits must be huge.

The only sad part is that they aren't at the full-deployment stage yet.There is a difference between enduser bandwidth and backbone bandwidth. This would be a backbone solution to get data from hundreds of users in one area to hundreds of users in another area, it would not be 100Gb/s at your home.

    That being said, this is really good tech and needs to be implemented ASAP. While these new techs have a super high entry cost, the maintenance cost is quite cheap as it takes less power/cooling to run them, and less repeater stations to get stuff from point A to point B. Plus the added data density will allow backbone connections to use the same tunnels and trenches to do a whole lot more work.

    The internet didn't really start in the U.S.A though. The 1st point to point network was in the U.S.A but the internet defiantly didn't start there. The internet was invented at CERN by Sir Tim Berners-Lee

    good luck boycotting when you're the only one without any internet service to your house...

    also doesn't help when they have monopoly on certain markets...

    until there is competition or Google Fiber is rolling in, you're just gonna have to get your bass taped...without any lubes...

    at least in my neighbor, there's choice between Comcast and Verizon...EVIL and LESSER EVIL...

    Google really needs to deploy their fiber network nationwide...that'll scare rest of the ISP in their pants....

    To put this in perspective, fiber over 2000 miles incurs a latency of about 16ms. 2 Tbit/s for 16ms is 32 gigabits, or about 4 gigabytes of data suspended *in* the fiber at any given moment. Crazy, or what?

    Wrong, the internet very much started in the US through DARPAnet which interconnected a number of military systems first and some universities before expanding. What Sir Tim did was come up with HTTP which increased the ability to browse the existing network more easily.
