Question : Optical carrier

Allright this is kind of a dumb question.....is there any way to have an OC3 or other OC connection?!?  I mean can you use it in a business or at home, or anyways what do you have to do to get it?  Oh yea and what is the bigest OC? I ve heard of an oc3456.
I know that OC are internet backbones....and i would really like to know who has these kind of internet connections.  I have also heard of a connection called twtd or something that has a speed of 2 Terabps!!!!!!!!!!!!!!!!! HOLLY COW!!

Of course you can . Just buy needed equipment and trace an optical line between your home and the nearest provider who can sale you this rate of access . I am not joking . In future we will have optical connection in every house everywhere , but now it is aviable only in some big metropolises and expesially in the business areas .
>Oh yea and what is the bigest OC? I ve heard of an oc3456.
Let clear some things . Optical Carier is a low-level standart(if we must be sharp standart is SONET) that cpecifies technology for telecommunication data transport . OC-1 is equivalent of 51.84 Mbps connection speed . So OC-3456 speed must be about 180 Gbps . But as I know the highest level in standart is OC-192 . In practice hase a standard called "72x72 switching" and devices designed under that standard could provide up to 3456 simultanios OC-1 connections .

Of course telecommunication operators .

I have never heard about twtd connection , but I think you are in mistake . There was a standard ( I can't remember how was called ) that allows network devices such as routers , firewals , switches provide ut to 2000Gbps internal bandwidth . But may be I am out of date .
Let's talk about services . To day's general standard for backbones is FastEthernet - 100Mbps and for end-node connection - 10Mbps . In my network I have GB backbone , 38Mbps over HFCN to end home users and FE over FX/TX to end corporative clients . But is that needed by users ? No , there is still no services to require thas speeds .
