OPTICAL FIBRE
Definition
An <OPTICAL FIBRE> is a <SIGNAL CONVEYING ITEM> that is a flexible, transparent fiber made by drawing glass (silica) 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 (data rates) than wire cables
