Is That An OC-768 In Your Pocket?

bdigit writes: "Qwest communications using Nortel Networks OC-768 was able to transfer 40Gbps over 435 miles(700 km) breaking the record for the fastest land speed record. Qwest has plans to begin deploying OC-768's in quarter three of 2001." Note: if they need beta testers, just lemme know! I can write a mean bug report ("My pr0n is only getting 30gps! Please fix!")

OC-n = (n = STS-1 = 51mb) * 768 or 48 or 12 or 3

T1,T3 are transmission rates that descibe electrical interfaces. A T1 link is 1.5mb ( bits )
T3 = 45mb. OC ( optical carrier ) is a BellCore
description of transmission in SONET networks. ( Synchronous Optical Network ).

The speed of OC-n is derived from the number of interleaved STS streams. STS-1 is 51mb per second
All OC-n rates ( lowest is OC-3 which sts-1x3 ) are derived from a multiple of this.

OC-768 = 768xSTS1 rate = 39168mb per second
OC-48 = 48xSTS-1 rate = 2448mb per second
OC-3 = 3xSTS-1 rate = 153mb per second

OC-n rates can be described as concatenated ( a fat pipe ). or Channelized whereby an OC pipe contains multiple channels ( STS payloads )each
of which can contain different payloads ( packets or atm cells ).
Oc-3c is a concat. fat pipe.
Oc-3 is a channelized pipe.

I'm a parent soon. I can hear myself saying...

"In my day, sonny, we only had a 64kbps connection to my house. Thats right. And that's when I was already an adult. Now every house comes with a standard 40Gbps line. Aren't you special. You don't know what its like to have to wait for your keystrokes to be echoed back to your terminal screen. Oh, sorry, you don't even know what a keyboard is do ya. Get outta here."
