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 (silica) or plastic to a diameter slightly thicker than that of a human hair.iber supporting only one mode is called single-mode or mono-mode fiber. The behavior of larger-core multi-mode fiber can also be modeled using the wave equation, which shows that such fiber supports more than one mode of propagation (hence the name).
