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.
An optical fiber or optical fibre is a flexible, transparent fiber made by drawing glass or plastic to a diameter 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, where they permit transmission over longer distances and at higher bandwidths than wire cables. Fibers are used instead of metal wires because signals travel along them with less loss; in addit
