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.
Optical fibers are also a huge part of making the Internet available around the world. When fiber replaces copper for long distance calls and Internet traffic, it dramatically lowers costs. To understand how a fiber optic cable works, imagine an immensely long drinking straw or flexible plastic pipe.For example, imagine a pipe that is several miles long. Now imagine that the inside surface of the pipe has been coated with a perfect mirror.hen fiber replaces copper for long distance calls and Internet traffic, it dramatically lowers costs.
