Fiber optic cables are really better than copper wires?

Recently the technology has proven to be fiber optic cable is rapidly replacing copper cables. Why? Since fiber optic cable to provide faster transmission and clearer signals. Goes out to longer distances in miles that stretch, making the connection more efficiently. There are many types of fiber optic cables in the market - and not all are equal. Here is a guide.

How it works

HDMI Cable

Fiber optics works by transmitting signals via light waves. It 'aFiberglass or plastic, where the light through. At the end of each fiber optic cable is a transmitter. If the information or signals to pass through these channels, it is converted into a light-emitting diode (LED), which passes through the cable.

Optical fibers are typically used in telecommunications, but also in the network, the power used, and the transmission of television signals.

Fiber optics vs. copper wires

Copper wires are fragile and difficult to maintain. MeanwhileFiber optic cables are durable and have a higher voltage. Apart from the light guides are also cheaper.

How to buy

There are two types of fiber optic cable: single-mode fiber and multimode fiber optic cable. The single fiber optic cable contains single strands of fiber transmission in one direction at a time. And 'ideal for broadband transmission. Meanwhile, the multi-fiber cable with multiple fibers, which are ideal for the transmission of signalsmedium or short distances.

When choosing a fiber optic cable, it is important for two things: the design and cable connector. Buy a loose-tube cable type for indoor use and full-wire for outdoor use.
Singlemode cables should only Fibre Channel ports, while the multi-mode FDDI cable feed must use the doors.
