FiberOptic Cables

FiberOptic Cables

• Fiber optic cable functions as a "light guide," guiding the light introduced at one end to the other end. 
• The light source can either be a light-emitting diode (LED) or a laser.
• The optical fibre cable is madeup of the glass materials which can the light. 
• Transparent glass or plastic fibers which allow light to be guided from one end to the other with minimal loss.

The optical fiber consists of three layers:

• Core 
• Cladding 
• Buffer Coating

                         

• Core is used to send the light signals.
• Cladding is used to improve the critical angle.
• Buffer coating is used to protect the core and cladding from the environment.

Advantages:

• Speed: Fiber optic networks operate at high speeds - up into the gigabits.
• Bandwidth: large carrying capacity.
• Distance: Signals can be transmitted further without needing to be "refreshed" or strengthened.
• Resistance: Greater resistance to electromagnetic noise such as radios, motors or other nearby cables.
• Maintenance: Fiber optic cables costs much less to maintain.
