Fiber optics technology

An optical fiber is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter typically slightly thicker than that of a human hair. Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications. Fibers are used instead of metal wires because signals travel along them with lesser amounts of loss; in addition, fibers are also immune to electromagnetic interference. Optical fibers typically include a transparent core surrounded by a transparent cladding material with a lower index of refraction.

Here is a collection of videos that introduce you how the fiber optics technology works:

    HOMEMADE OPTICAL FIBER FIBRE OPTIC LIGHTING CABLE DIY Do it yourself Fiber Optic Cable Optical Fibre

    This is an introduction to how to make your own optical fiber optic cable DIY for indoor lighting applications. I imagine it could be used for short data transfers optical cable but will not say for sure.

    DIY Fiber Optic Cable

    In this video, I show you how to make a fiber optic cable at home. This will allow you to bend light. You will need glass rod (I used borosilicate), heat shrink tubing, a heat gun, a torch, safety glasses, proper ventilation, and finally, a laser to test it all out. I was able to make 3 feet in a couple of hours. Enjoy!
