For years I've heard companies brag about their high-speed fiber optic systems, and never knew what it meant. I recently learned about the many benefits of this system of transferring information, and wanted to pass on my knowledge to consumers and corporations alike. I can't say enough about the advantages of upgrading to fiber optics. I created the About Fiber Optics Cables site to provide you with simple information about the many ways you can incorporate fiber optics into your communications networks.

Replacing Copper Cables with High Speed Fiber Optics Cables

For many years copper was the standard for transferring communications signals. In recent years copper wire has been replaced with a new system called fiber optics cables. You've probably heard of this technology and how it is used by many different industries including communications, the military, aerospace, and medical robotics just to name a few. These cables allow for higher speeds of signal transfer, provide greater resistance to electromagnetic interference from things like radios, engines and other nearby cables, and are known for being much easier to maintain than the copper wires.

Unlike copper wires, which use electronic pulses to transmit information, fiber optics cables transfer information using light pulses. Electronic codes are sent from copper wires to a transmitter. The transmitter then translates the electronic codes into equivalent light pulses. These pulses are then sent down fiber optic lines to the appropriate medium.

The Three Types of Cables

There are three basic types of fiber optics cables are single mode, multimode, and plastic optical fiber. Essentially, these cables serve as a light guide, sending light pulses, or laser signals from one end of the cable to the other. Without getting too complicated, when the light source is pulsed on and off it gets converted at the other end of the cable into a series of ones and zeros. These digits create a code that resembles the original signal. Sometimes repeaters, or light strengtheners, are used to ensure the signal is sent without interruption or corruption.

When it comes to fiber optics cables single-mode fiber gives you the fastest rate of transmission of the three most popular cable types. Because it has a small core and comes from a single light source, the signal is less likely to be distorted or corrupted by other light sources. These cables are also called mono-mode, uni-mode, and single mode optical wavelength.

In multimode cables several light waves are sent through a single core. These cables are best for medium length transmissions and tend to lose signal strength when used for longer cable runs. The plastic optical fiber mentioned above is a less expensive option for the transmission of several light waves. It is best used for short cable runs.

A Brief History of Fiber Optics

Fiber optics was introduced in the '70s as a replacement for copper cables. This technology was first applied to the telecommunications industry. It is the basis for long-distance service from cities across the country. Cable television companies are also using fiber optics cables in increasing numbers today. These cables provide faster service and often reduce the need to send out technicians for repairs and restoration of service. Larger organizations like colleges, hospitals and industrial plants have all integrated their information systems with these cables to create a central office network. This has increased communication, productivity, and the sharing of information.

You can find more information about these cables and their accessories in the following pages. There are so many businesses that can benefit by upgrading to this faster, more reliable system of transferring information. You can find additional information about companies that provide everything from microwave devices to RF products on the Internet.
