It can be one, the other, or both. Originally T1 was fiber with the last mile being copper. These days it is more common to have fiber run all the way to the POP.
It is metal as it conducts electricity and it is on the left side of that big black line in the periodic table. It is in fact used in wires for it's conductive properties.

what are the elements of fiber
Relates that if held under constant pressure the ratio of Vol/Temp remains constant. i.e, V1 / T1 = V2 / T2 (where T is in Kelvin)
You get a really big explosion. Sulfur mixed with water is BANG!!!
A T1 connection works by using a fiber optic or copper line to carry data faster than a standard phone line. It carries data at a rate approximately 60 times faster.

A T1 line speed refers to the speed at which a T1 line is able to transfer data., often written in kilobytes per second. T1 lines these days see less use and have been replaced with fiber optics.
A connection between two telephone central switching offices. The basic trunk line is called a T1 line. They provide many connections in a single cable, originally they were bundles of copper wire twisted pairs but now are often just a single fiber optic line.

T1 line, it means that the phone company has brought a fiber optic line into your office (a T1 line might also come in on copper). A T1 line can carry 24 digitized voice channels, or it can carry data at a rate of 1.544 megabits per second. If the T1 line is being used for telephone conversations, it plugs into the office's phone system. If it is carrying data it plugs into the network's router. A T1 line can carry about 192,000 bytes per second -- roughly 60 times more data than a normal residential modem. It is also extremely reliable -- much more reliable than an analog modem. Depending on what they are doing, a T1 line can generally handle quite a few people. For general browsing, hundreds of users are easily able to share a T1 line comfortably. If they are all downloading MP3 files or video files simultaneously it would be a problem, but that still isn't extremely common. A T1 line might cost between $1,000 and $1,500 per month depending on who provides it and where it goes. The other end of the T1 line needs to be connected to a web server, and the total cost is a combination of the fee the phone company charges and the fee the ISP charges. A large company needs something more than a T1 line. The following list shows
A T1 is copper, and OC3 is fiber optic, so there is no way to make a T1 into OC3. Speed on a T1 is 1.544 Mbps, and speed on the OC3 is 155.52 Mbps, so in rounding, you need 100 T1 lines to equal the speed of an OC3.
To set up a T1 service, you must run fiber optic between locations. The line is used only for internet connections, and nothing else. It used to be the fastest before cable modems.
T1 stand for how fast your Internet connection is going to be. T1 is the fastest of all, this would be a very high speed internet connection ( usually using fiber optics). The term T1 refers to the encoding.
The costs of a business installing a T1 line may vary depending on where one is located. It appears that a T1 line can cot up to $2,000 (US) and this may or may not include installation or maintenance of the T1 line.
When used as a Private Line or MPLS, this is as secure as your lan. If you connect the T1 to the internet, it is not secure. www.intelletrace.com
