Terabit Fiber (In 2010) 182

Posted by CmdrTaco from the sign-me-up dept.
Paul Heavens writes "A Japanese company has developed technology to transmit a two-hour movie in 0.5 seconds, the world's fastest speed achieved with fibre-optic cables in the field, it says. Kansai Electric used fibre-optic cables on power-transmitting steel towers to achieve the speed of one terabit per second, which is more than 100 times faster than inter-city data transmissions currently in use, a spokesman says. The company, Japan's second-largest power supplier, has not decided when to put the technology into practical use but says it is possible that it would come in 2010 or later."

Even those CLECs in the DSL biz have to go through the TelCo just to resell the same lines.

    Over the years, I've been tracking the waiting attention span on my downloads and those who got from me. I've ran BBSes since 1200 baud modems were $500.

    The 3 minute mark seems consistent over the years as the shortest period of time necessary to acquire something of value. Shorter times are nice but not needed.

    To download a 2 hour HiDef movie in 3 minutes, we'd need a connection speed of 222mb/s (28MB/s). I can see little need for a format beyond this at any time in the future. In fact, in 1993 I figured a preferred video resolution would be 2560x1440, not much greater than 1920x1080.

    In the '60s, probably centered on the CDC 6600, an idea was promoted that a balanced' computer would have capabilities in a ratio. The 3 M's was one with 1 MIPS, 1 mbps, and 1 megabit of memory. So, it could executed 1,000,000 instructions per second, communicate to disk at 1,000,000 bits per second (100,000 bytes per second) and had 1,000,000 bits of RAM (one system had 130,000 bytes of RAM, for example).

    The box i'm using to edit this note executes on the order of 1 GIPS, with 100 mbps, and 10 gigabits of memory. That is 1,000,000 instructions per second, 100,000,000 bits per second (10,000,000 bytes per second) to disk, and has on the order of 10,000,000,000 bits of RAM (1 GB). (These numbers are rounded, and, no, i'm not terribly interested in my-box-is-faster-than-yours pissing matches - its just an example).

    So, if communications speeds will be 1,000,000,000,000 bits per second anywhere by 2010, that implies a computer with at lest 10 GIPS and 10 GB RAM - which doesn't seem that unlikely in five years.

    Oddly enough, I'm hoping to still be running this box in five years. Its only two years old, and I don't really want to get a new one. That is, i don't want to spend the money to replace it. More importantly, i don't want to do the administration involved to get a new machine up and running with my current set of capabilities.

Even the point quoted in the summary, "2 hour movie in 0.5 seconds", is useless for anything but getting a technohick to say "wow".

But not to nerds - to us, it's "Libraries of Congress per second", which was expectable nonsense when reporters hadn't used the Internet.
