Does anything that I'm about to write really matter to Ian?
Nope, not in the slightest, so I wish him the joy of his new found cyber power!:salute:
For everyone, there are an awful lot of factors involved in "Bandwidth" beyond simple transmission path....so I would caution anyone in jumping to conclusions regards speed (use of the term "Bandwidth" is a particular pet peeve of mine--I work in the industry).
The biggest factor in most systems is "latency". Since computers talk to one another full duplex, and most transmission systems are not balanced (i.e. they send and receive at the same rates) your actual "conversations" (up and down) are always going to default lower than what you think. So you can have the incredible download speeds, and really good upload speeds, but it really doesn't mean that much (why I hate these meters...they are valuable, but they miss a good part of the story). Transmission speed is not simultaneous (even when you're talking to someone in the room) and that's especially true of TCP/IP systems and networks. Note, we've not gotten to your particular system processing speed, communication speeds, and ability to move data around the board yet. We've also not talked satellite systems, which are a whole other bag of worms.
And while fiber is a wonderful medium for transmission systems, there is nothing inherently better about in terms of transmitting data than regular CAT V or coax. It's advantage is that given long haul communications it provides better bang for the buck, and is generally more resistant to damage and experiences little line loss over distance (don't anyone tell you there isn't any, because that is not true). However, damage a fiber link and watch the fun begin...it's hard to fix, requires specialized equipment, and is not particularly suitable for short runs being more expensive per foot that other options. Otherwise we'd all have fiber modems and converters in our computers.....The U.S. Army for years envisioned using fiber tactically for voice and data comms, but it's rarely done even now.....just too much of a pain.
So, when people tell me their speeds have dramatically increased via the use of fiber I generally have a few questions for them....what I tend to find out is that your Telecom company -- prior to putting the fiber in the ground -- completely re-designed their infrastructure and architecture before they made the major investments....your speed increase generally comes from that....not the medium itself.
