Comment Re:A worrying trend (Score 1) 41

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

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.

The receive sensitivity on common '10G' DWDM optics is frequently down to -24 dBm or lower. That's less than a hundredth of a mw. So from that perspective, that +0 or +3 dBm is rocket hot. 100G optics aren't quite as sensitive, but still down to -14 or -17 or so depending on the specs.
