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.
Fibre's a new technology. That means we can't be totally sure devices like these will work over a fibre phone line. If you do use a monitored security alarm or a medical alert alarm, it's best to check with the manufacturer to see if it will run on fibre, or if you will need to upgrade.
