Fiber optic cabling
What are fiber optic cables and how they differ from metal wiring.
Fiber optic connectivity has ushered in a new world of high speed voice, video and data communications. Since the invention of the electromagnet and the telegraph in the 1820s, electrical wiring has utilized copper : high conductivity , high tensile strength and high ductility. Copper is great for electrical applications, but when it comes to network and telecomm situations optical fiber wins.
A TECHNOLOGY THAT USES GLASS (OR PLASTIC) THREADS (FIBERS) TO TRANSMIT DATA. A FIBER OPTIC CABLE CONSISTS OF A BUNDLE OF GLASS THREADS, EACH OF WHICH IS CAPABLE OF TRANSMITTING MESSAGES MODULATED ONTO LIGHT WAVES.
