As opposed to most types of cable, fibre-optic cable (also known as optical fibre) uses light instead of electricity to transmit signals. Obviously, light is the fastest method of transmitting information, but fibre-optic cable has the additional advantage of not being subject to electrical interference. Thus, you can run it just about anywhere. Since light meets very little resistance, you can run fibre-optic cable over very long distances without having to boost or clean the signal.


Fibre optics also involves speed. You can send signals at more than 10 GB per second. And even at that velocity, the signal is much cleaner than traditional electrical cabling. Comparing fibre-optic cabling to coaxial cabling is sort of like comparing digital information to analog information. (It really isn’t much of a comparison. Fibre optics is far more impressive.)


Fibre-optic cable must have a light source that generates a signal. Connectors, repeaters, couplers, and other components, which exist in most standard networking systems, serve to route, boost, and deliver the signal. First, you need something that will help you transmit light through the cable. This something is called a transmitter. Transmitters come in two varieties: LED (light emitting diode) and laser. The transmitter includes a light source and a driver, which modulates and uses an electrical signal to power the light source. Think of a fibre-optic cable as an unusually long laser that carries a light beam along a controlled path rather than emitting it through the air.


Finally, you need a receiver that will convert light signals back into
electrical signals. Receivers possess photodetectors that convert light
into electrical signals, amplifiers that boost signals, and output devices
that transmit those signals.

The advantages of fibre optics

• There’s little interference from EMF devices, and fibre-optic cables don’t
   interfere with other devices.

• Fibre-optic cables are difficult to tap because they don’t emit signals that
   can be monitored. They are very secure.

• Fibre optics is faster than most other transmission mediums.

• The signal has a constrained loss rate, which means that very little of
   a signal is lost over rather long distances.

• Fibre-optic cables are safe to handle because high voltages aren’t involved.

• Fibre-optic cable is easier to install.


At MKD Electrical we can supply and install the fibre optic cable to the customers needs. We will then carry out the terminations and carry out testing end to end.


The hardware equipment is usually then supplied by the customers IT professional, Once again, suited to the customers needs.
