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.
Fiber optics work by passing light through the fiber from one end to the other with relatively little loss. By using a strong laser on one end and then wiggling that laser on and off, we can encode a message on the light. By doing some very clever encodings on that message, we can get useful light out on the other end.
