How fast is OC3?

[Shadowfire]

I was jus' wondering since thats what we got installed at work a few days back, and i couldn't figure it out, since download speeds kept rising up while downloading...

So anyone knows whats the max speed of OC3?
And also whats the top speed of T3?

Merci beacoup

I think T-3 is 45 Mbps (megabit) and OC-3 is 155Mbps. I might be wrong though.

Thats correct, or close enough at least

Where do you work? Must be one heck of a business. Are you sure it's an OC-3 and not a DS3? A DS3 has the same speed as a T-3, but it generally used for tele-com companies.

Nope, its OC3, i have a manual infront of me on how to operate the damn Sun server that controls the OC3 for my floor... freaky stuff, Sun Solaris - ugh...
And i work at Lam Research - thats in Femont, CA, as an IT (high position parents rule!).

19 megs a second maybe?

 

OC-1 = 51.85 Mbps
OC-3 = 155.52 Mbps
OC-12 = 622.08 Mbps
OC-24 = 1.244 Gbps
OC-48 = 2.488 Gbps
OC-192=9.952 Gbps

Happy?

<< OC-12 = 622.08 Mbps >>


hmmm thats what they had in Lawrence Berkeley National Lab when my dad used to do his PostDoc there.



<< OC-192=9.952 Gbps >>


When i will be a zillioner like Bill Gates, thats what i will have at home!

Here is a site that will tell you what speed most things are. Just like my signature I am saving my aluminum cans for 1

WHOA...!

I want this: DWDM - 10Tbps, downloads a 1.3x10^5 MB in one second, thats mucho megabytes, and mucho bandwidth.

Nice bandwidth, But I can't think of one server that can even begin to spit out files as fast as my 7MBit cable connection can take it down

 

[Shadowfire]

I bet that God's server can!

I was about to say the same thing. I have hard enough trouble finding servers that can chew out 100KB/s, let alone the 6Mbps that my xDSL connection can do. But, I'm not complaining one bit. For once in my life, I'm waiting on someone else's technology to increase.

Wow, now I could run a sweet FTP server off an OC192.. or maybe 10 sweet ones.

We have some equipment in the lab that'll run OC192 (not externally though), and the extra bandwidth of DWDM wouldn't help you. Basically DWDM is multiplexing a group of signals (like 1 Gig each), where each signal gets transmitted over a "color," called a "Lambda."

It's kind of like cable TV, there are a bunch of channels/frequencies (colors/lambda) on the same media, the magic is combining the signals such that they can be split out at the other end.

So DWDM is really umpty-squat channels, each transmitting a fixed bandwidth, the stuff we have (Nortel Optera Metros)will do up to OC48 per channel (but we only use it at one gig each). We demo'd it at Interop with three Lambda active, two Gig Ethernet, and one ATM OC12.

It's really just a (cool) dumb pipe, layer one.....a bandwidth multiplier to get multiple ten pound packages of sh*t through the same one pound pipe. It's one of the technologies that allow the Telcos to give you dialtone or bandwidth cheaper than in the "good Old Days."

Some other pretty slick stuff for the folks with big campuses: check out Ocular.com. It's WDM/DWDM stuff..." Cheap"

FWIW
