Continued Research About Fiber Optic

An optical fiber (or optical fibre) is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair. (So it is not conductive.)

Optical fiber can be used as a medium for telecommunication and computer networking because it is flexible and can be bundled as cables. It is especially advantageous for long-distance communications, because light propagates through the fiber with little attenuation compared to electrical cables. This allows long distances to be spanned with few repeaters.

There are many different types of optical fiber.


1/Multi-mode fiber

Fiber with large core diameter (greater than 10 micrometers) may be analyzed by geometrical optics. Such fiber is called multi-mode fiber, from the electromagnetic analysis (see below).

2/Single-mode fiber

3/Special-purpose fiber

The price of this material depends on its thickness and length.

The link is under below.

There are some different types of fiber optic on this website.

I bought each of them to do some experiment and found that the light through them are really weak.

And even it said on the website that Side Beam fiber optic cable can  transmit light over the entire length of the solid core optic, without electricity or heat, the light is very faint and only can be seen on the both ends of the filament.

Here are some example of this material.


I am think about doing an interactive mask with this material.

    1. Yes. Cause I really want it light over the whole length of the fiber optic. However, I do not why I can only see the light on the ends of it, and the light in the center of the it is really dim.
