A fiber optic cable is a network cable that contains strands of glass fibers inside an insulated casing. They're designed for long distance, very high performance data networking and telecommunications.
Compared to wired cables, fiber optic cables provide higher bandwidth and can transmit data over longer distances. Fiber optic cables support much of the world's internet, cable television and telephone systems. How Fiber Optic Cables WorkFiber optic cables carry communication signals using pulses of light generated by small lasers or light-emitting diodes (LEDs). The cable consists of one or more strands of glass, each only slightly thicker than a human hair. The center of each strand is called the core, which provides the pathway for light to travel. The core is surrounded by a layer of glass called cladding that reflects light inward to avoid loss of signal and allow the light to pass through bends in the cable. The two primary types of fiber cables are called single mode and multi mode fiber. Single mode fiber uses very thin glass strands and a laser to generate light while multi mode fibers use LEDs. Single mode fiber networks often use Wave Division Multiplexing (WDM) techniques to increase the amount of data traffic that can be sent across the strand. WDM allows light at multiple different wavelengths to be combined (multiplexed) and later separated (de-multiplexed), effectively transmitting multiple communication streams via a single light pulse. Advantages of Fiber Optic CablesFiber cables offer several advantages over traditional long-distance copper cabling.
Some better known FTTH services in the market today include Verizon FIOS and Google Fiber. These services can provide gigabit (1 Gbps) internet speeds to each household. However, even though providers also offer lower cost, they typically also offer lower capacity packages to their customers.

A network cable that contains glass fiber inside an insulating casing is known as fiber optic cable. This cable is specially designed for long distance transmission. Fiber optic cables use pulses of light generated by LEDs to carry signals. It supports a higher capacity. Fiber optic cable lessens the requirement for signal boosters. As it is less susceptible to interference, hence it does not require any kind of special shielding. For that reason, the industry of fiber optics is growing consistently.

It's wonderful that fiber optic cables have a higher capacity than regular cables. My wife and I would like to move to a new house, and we want to make sure that we can get the fastest internet possible there. We'll be sure to look further into our options for homes that can utilize this high capacity cabling for internet-related purposes in the future.
