In fairness, this is layer 1 stuff that they can't really backdoor. I guess they could create a big red "shutdown" button in Beijing though.
The routers are what you have to worry about forwarding select interesting traffic back to the mothership.

I still wouldn't use Huawei transport though, it's honestly not that cost competitive with home grown vendors like Infinera and Ciena.

That's no acheivement. 1tbps over 1000 miles is easy. That's ten OTU4 channels running over a simple DWDM system. All the coherent hardware out there has great OSNR performance so running through 10 amplifiers over 1000 miles of OSP fiber is an everyday project.
What this article is about, what everyone is working on in the optical space, is a single 1tbps super-channel. Everyone's already concluded we can't hit 1tbps on the same 25ghz spaced channels we use for 100G, so they are working on concatenating 12.5ghz slices into a larger superchannel which may be 50, 62.5, 125 ghz spaced, whatever the needs require. However, that's hard to understand so the blurb is just 1tbps over 1000 miles, which sounds impressive to someone who hasn't already been doing that for years.

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.

It just shows that at a certain level of volume it makes more sense to produce the product yourself. These companies need to move terabits of traffic long distances. If they did this purely by leasing capacity from traditional telecoms they would be paying millions of dollars per month. For that kind of money, you can build one hell of a transport network and then have control as well as cost savings. Unfortunately with Submarine routes the only reliable way to get fiber in the cable is to be a member of the consortium building it. You can't come along years later and buy dark fiber because it's all in use quick.

I grok the snark, but in my experience people who take their own initiative on learning and personal development gain 10x more than people who get sent to some boot camp or seminar on their employers dime. If you are learning something useful it all comes back to you in a future paycheck anyway. "I haven't been trained on this" is generally an excuse I hear from people who wouldn't know their ass from a hole in the ground even if they did attend a 3 day ass-recognition boot camp.

This could be a low power way to sync your phone with your watch or your watch with your TV or your TV with your robotic vacuum cleaner. Wifi has a lot of complexity built in, and uses a lot of power. This could also have some niche applications in noisy environments like electrical utilities.

Comment: No applications in Telecom (Score 2) 64 64

Before anyone says anything about fiber optics, this is useless for any application other than short range wifi/bluetooth replacement type technologies. The attenuation of light in fibre has a minimum around 1550nm, infra-red. Shorter wavelengths experience high attenuation due to scattering. Longer wavelengths have more absorption.
