Yes true
Yes, that is true - and that is commonly used in modern technology, but especially to transmit information. Note that in an optic fiber, light travelling along the fiber is simply reflected back inside, if it reaches the borders.
No. An optical fiber is a slim hair composed of glass. Glass is a fine insulator, and an optical fiber doesn't conduct electricity at all.

Coaxial cable, Optical fiber cable, Twisted Pair
The optical fiber can be used both as unidirectional and bidirectional. The main application of optical fiber is in long-distance links, so there exists no need to employ them as unidirectional. For each direction different wavelengths are used to modulat the signals. At the same time many bidirectional signals can travel through the same optical fiber.
Optical Fiber1. Photon has no mass, and it can travel faster than electron2. In multi-mode fiber, several channels of data can be transmitted at the same time

mode means path, the way in which light travel, in the fiber means angle in multi mode fiber light can travel in more then one angle so it is called multi mode fiber. but in single mode fiber there is dedicated path or single path through which light beam/source can travel.

Usually, there is a laser diode that is optically coupled to the fiber.
One of the advantages of optical fiber is that it is NOT susceptible to cross-talk.
