Huawei, Proximus Demo 1Tb/sec Optical Network Transmission

Amanda Parker writes: Proximus and Huawei have demonstrated speeds of 1 Terabit per second (Tbps) in an optical trial. The speed, which equates to the transmission of 33 HD films in a second, is the first outcome of the partnership between the two companies which was formed in January. The trial was conducted over a 1,040 kilometre fibre link using an advanced 'Flexgrid' infrastructure with Huawei's Optical Switch Node OSN 9800 platform.

1tbps is easy

[Shatrat]

We've been turning up 1tbps optical transport for years, this is easy. You can do this with commodity parts. What they've probably done, which isn't in the summary or TFA, is turn up a single 1tbps super channel over a flexible grid ROADM. That's currently in the development stage with a lot of vendors, such as Alcatel, Ciena, Infinera, Cisco and more. That would allow the entire ROADM system to scale up the N-Terabits, where N is going to depend on how many superchannels can be crammed into the C-band. Probably on the order of 50-100 terabits per second fully loaded.

I was thinking the same thing, even passive DWDM systems and 100G optics should be able to do 4Tbps over 40 channels - 8Tbps over 80 channels if you've got 50Ghz spaced optics. The passive systems aren't even that expensive, although the frequency-specific optics on each side add up quickly. ROADM systems are nice because you can drop off specific channels and manage amplification and such automatically. In the telecom industry we've been doing this for many years with 10G and OC48/192 links since its cheaper than plowing in new fiber, 40G and 100G are starting to show up now too.
Here's the kind of stuff we're talking about:

People who don't want their network backdoored by the US? Have you missed some info lately?
