What am I gonna do with 1 GB? I just close the door on my WiFi point with one open socket to create a high WiFi pressure zone. If you close your windows it lasts like a day.
I like your idea but you are limited to 100M or 300ft, let's scale it up. Single mode fibre can do up to 400Gb per strand pair up to 40km (I'm not converting that to freedom units)
Get yourself a 144 core cable or 72 pairs.
40Km of cable for a total length of 2,880Km of fibre and at 400Gb per meter that is just over 1,000,000 Gb or 1 petabit. 8 bits to a byte for a total cable capacity of 140 terrabytes of data.
I really don't like that you have two units in your title. A spool is a unit, although a crude one. Your title would be much easier to read if you had simply said, "Network cable can hold 1GB of internet traffic per meter."
No, you're right. It is, but your title was a little redundant.
Think of it this way. You could have said, "A planet of warehouses of pallets of spools of cable holds 1 GB per meter..." It's still a correct statement, but it's redundant. Any amount of cable holds 1 GB per meter. You don't need to say an amount at all.
