Carpe diem is a Latin aphorism, usually translated seize the day, taken from the Roman poet Horace 's Odes (23 BC). 1  1 Translation.
Fiber optics (optical fibers) are long, thin strands of very pure glass about the diameter of a human hair. They are arranged in bundles called optical cables and used to transmit light signals over long distances. If you look closely at a single optical fiber, you will see that it has the following parts: 1  Core-Thin glass center of the fiber where the light travels. 2  Cladding-Outer optical material surrounding the core that reflects the light back into the core.
To put it simply, fibre optics is a technology whereby a signal like video, data or voice, is concentrated on a light beam and sent down a glass tube over large distances, with very little distortion and loss. The principles of fibre optics are simple and easy to understand.here are 3 different types of fibre optics cable available. These are: 1. Step Index. This cable has a distinct index of refraction for the core and the cladding. It is the cheapest type of cable and causes deformation due to the various path lengths of the light ray. This is called modal distortion.
