Advantages of Fiber-Optic Cables
Consider shining a flashlight beam down long corridor that has several twists and turns. Because light can only travel in a straight line the light is not able to reach the end of the hallway. However, if mirrors are placed in each corner of the corridor the light will bounce off the mirrors and continue down the hall. This is analogous as to how light travels through fiber-optic cable.
The light traveling inside a fiber-optic cable moves along its core, or down the “corridor,” by continually being bounced off the reflective cladding on the inside of the cable shielding, a phenomenon referred to as internal refraction. Because the cladding acts as a mirror, and doesn’t absorb light, the light is able to travel for great distances.
Due to the way fiber-optic cables transmit data, with light and without the use of electrical current, the benefits and advantages of fiber-optic cables are creating a revolution in the communication industry. Fiber optics are increasingly being adopted in various sectors, most notably computer and telecommunications networks and Fiber Internet providers.
Advantages of fiber-optic cables include:
- Less expensive construction. Several miles of fiber-optic cable can be manufactured for roughly half of the equivalent length of traditional copper cable. This saves the service provider money which they can pass on to the consumer.
- Having a narrower diameter, allowing the wires to be drawn through smaller holes than copper cables.
- Having a higher carrying capacity than copper, allowing more fibers to be bundled into a single cable. This permits more service lines to be routed through the same cable.
- Presents with less signal degradation than copper cabling. Unlike the electrical signals used in copper cables, the light transmission from one fiber never interfere with signals from other fibers in the same line, resulting in clearer signal reception.
- Less power consumption. Because of the lower signal degradation of optical fibers less-powerful transmitters are needed, lowering costs to the provider and you.
- No risk of fire, as no electricity passes through fiber optics there is nothing to cause ignition.
- Being ideally suited for carrying digital signals, which are perfectly suited for use in computer networks.
- Having a high flexibility, allowing signals to be transmitted and received around objects. This makes fiber-optic cables perfect for use in cameras and scopes for medical-imaging devices like laparoscopes, endoscopes and bronchoscopes as well as mechanical-imaging devices such as cameras used in construction and inspection operations.
