New Data Transmission Record — 14 Tbps
deejne writes to alert us to a new bandwidth record: Nippon Telegraph and Telephone has announced data transmission at a rate of 14 terabits per second over a single optical fiber. The paper claims the previous record was "about 10 Tbps." In the new experiment, NTT sent data over 160 kilometers (nearly 100 miles) of optical fiber, in 140 channels of 111 Gbps each.
I'd like to know what the cost of the required equipment is. We know that hardware has a premium for the newest and fastest and it would be interesting to see what the premium is in this case. Maybe it would be cheaper to run 14 1 Tbps links instead of a single 14 Tbps link. Sure, if I already have the fiber in place, then using it for higher speed would be the way to go. However, if I am in a position where I am about to lay fiber anyway, I don't really care about those costs since I will be paying them anyway.
Reading code is like reading the dictionary - you have to read half of it before you can go back and understand it.
Each advancement in technology allows the main internet backbone companies to purchase one very expensive fast pipe and share it between all the customers (ISPs) of a country or state.
These things need to be thousands of times faster than your home connection because each one will carry thousands of times more data.
Its no good one single person having all that bandwidth if there is nobody else to talk to at that speed.

A link that fast wouldn't help you. There isn't enough seed bandwidth on TPB to give you 14Tbits/sec, nor is there the backbone bandwidth. And you'd need a hell of a RAID subsystem to manage handle writing at 14Tbits/sec sustained.

While impressive, the feat was accomplished over a single optical fiber using proprietary amplifiers not in production. It certainly is innovative, but it is not an indication of speeds you will see in consumer level services.
That goes without saying, right? It is, after all, a record. People don't usually turn to the Guinness book of world records for guidance on, say, what a realistic number of hotdogs is to consume within 12 minutes.
Now of course, greater bandwidth is cool and all, but 14 Tbps is obviously impractical for actual use, even in specialist medical imaging applications -- for the simple reason you couldn't fill up your harddrive (or even RAM) as quick as that!
