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.
With fiber, the source can be in an easily accessible location and the fiber in any remote place. Changing the source is no longer a problem. How Fiber Optic Lighting Works. Fiber optic lighting uses optical fiber as a âlight pipe,â transmitting light from a source through the fiber to a remote location.
