Earth rotates or spins toward the east, and that's why the Sun, Moon, planets, and stars all rise in the east and make their way westward across the sky.
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 (data rates) than wire cables.ptical fibers are connected to terminal equipment by optical fiber connectors. These connectors are usually of a standard type such as FC, SC, ST, LC, MTRJ, or SMA, which is designated for higher power transmission.
Because fiber-optics uses light instead of electricity to transmit data, the frequencies that are used are much higher and the data capacity is much greater. The fiber-optic cable itself is made from glass or plastic which is not susceptible to electromagnetic interference like metal cables.This allows data to flow over great distances without degrading.he fiber-optic cable itself is made from glass or plastic which is not susceptible to electromagnetic interference like metal cables.
