Yes.
Yo­u hear ab­out fiber-optic cables whenever people ta­lk about the telephone system, the cable TV system or the Internet. Fiber-optic lines are strands of optically pure glass as thin as a human hair that carry digital information over long distances. They are also used in medical imaging and mechanical engineering inspection.
Mechanica lines
You will get a meaningless jumble of lines.

Equipotential lines are lines that are perpendicular to the lines representing the electric field of a particle. A particle can travel freely of equipotential lines without doing any work.

These days it's all fiber optic lines. I don't think you will be able to find anyone to do this.
Fiber optic cables, made from glass, are gradually being used to replace copper telephone and cable television lines. It will be some time before all the lines are fiber optic, however.
It can be either or depending on the circuit, here's a link that will help you more: http://communication.howstuffworks.com/fiber-optic-communications/fiber-optic.htm

T-Lines are mostly high-speed fiber optic communications lines. (example - T1, T2, T3 etc...)

There is only 1 answer,corporate greed.
There are many purposes of a fiber multiplexer. Fiber multiplexers are made to allow the transport of multiple E1 or T1 lines and Ethernet over fiber optic links. Fiber multiplexer also allow voice (phone) over fiber fiber transmission.
Its the cable used now days for technology lines. In the old days they would lay copper lines, and now optic cable are lighter, faster and cheaper. This has been a brake through.
