Fiber optic cable is undeniably the superior choice over copper when it comes to setting up brand new cabling installations, as well as upgrades - including desktop, horizontal and backbone installations. The lower costs and increased proliferation of media converters is making the migration from copper to fiber effortlessly easy, with converters delivering seamless links and also supporting the use of existing hardware.


Because fiber optics transmit signals through their core of glass (which is an insulator) as light and not current, they can carry signals through places where EMI would normally block transmission.


  • Fiber can be submerged in water AND is much less vulnerable to temperature variations.
  • Fiber is immune to EMI (Electromagnetic Interference), RFI (Radio-Frequency Interference), impedance problems and crosstalk.

How would this would benefit you and boost your ROI? Your fiber cable can be run alongside industrial equipment with zero impedance!

  • The pulling specification of fiber is up to 10 times greater than copper cable!
  • It’s smaller size means it is much easier to handlespeedier to install - and iseasier to test than its copper counterpart.


Data Security
 Magnetic fields and current induction generate noise in signal-carrying conductors and allow the information on the conductor to be leaked out. Shielding the wire can reduce the problem but still allows sufficient signal leak to enable tapping!
                In high definition contrast, fiber is the most sophisticatedly secure medium to employ when carrying sensitive data because they do not radiate electromagnetic energy as the emissions can’t be intercepted without actually cutting into the fiber itself. Even so, physically tapping into the fiber undetected requires an immense degree of expertise. In the event of your cable being tapped, it is easy to monitor because the cable will leak light, and will cause the entire system to fail.
             Having one centrally-located fiber network means you can avoid spreading your network through the building in wire closets – which also tightens up on your data security.


Due to subtle variations in electrical potential, metal cables can encounter signal transmission problems, like ‘ground loop’ where the difference in ground potential at two ends of a wire becomes comparable to the signal level, with stray currents causing noise. The bigger the differences, the bigger the potential for component damage!(Electric utilities are most at risk due to their power plants and switching stations having potentially large differences.)
        Outdoor cables in some computer networks face the danger of being hit bylightning, causing detrimental damage to wires and other cables involved in the network. (Protective devices to block currents and voltage surges are fairly effective, but unfortunately not fool-proof.)
        To avoid ground loops and power surges, fiber optic cables can be made non-conductive by excluding metal in their design. This is an economical solution for indoor applications, but becomes exponentially more expensive in an outdoor application because of the need for special strength members. The higher cost, however, is worth the elimination of ground loops and protection of electronic equipment against surge damage.


Transmitting signals electronically, in certain circumstances, can be highly dangerous because most electric potentials generate sparks which, ordinarily are non-threatening, but can trigger a massive explosion in an environment where the air is saturated with explosive vapours. e.g. an oil refinery or chemical plant. The perfect risk-eliminating solution? Fiber optics. They don’t carry current and therefore are unable to create hazardous sparks.


Fiber cables are easier to install due to their smaller size and flexibility – which means they are the most effective alternative to increasing the transmissions capacity of wire cables (which would increase their thickness and rigidity.) Another bonus is that fiber cables can run along the same routes as electric cables without picking up excessive noise.

INSTALLATION TIP: Streamline and simplify installation in existing buildings by running fiber cables through the ventilation ducts. (Remember that fire codes call for plenum cables to be made from cost-inflating fire-retardant materials.) An additional benefit is that the lightweight flexibility and smaller size of fiber optic cables also make them easier for use in portable or temporary installations.

6. NICE FROM FAR: Boosted, Distance-Demolishing Bandwidth

Fiber optics have phenomenal capacity to carry high speed signals over long distances minus the need for repeaters, with the information-carrying capacity increasing with frequency.

FIBER FACT: fiber optic cable has a bandwidth parameter of 400MHz/km compared to coaxial cables’ bandwidth of just a few MHz.km – which is a massive influencing factor in why you should opt for fiber in data communications. Also, by adding fiber to a wire network, it will allow the network to reach terminals outside of its normal range. Terminating fiber has been vastly improved by new advancements in technology, withquick-fusion splicers allowing lightning fast auto-alignments which, as you know, ensures absolute accuracyPig-tails and pre-terminated cable also improve the speed and ease of making field connections.

FIBER FACT: Laser-optimized OM3 50-micron cable has an EMB of 2000 MHz/km. Laser-optimized OM4 50-micron cables has an EMB of 4700 MHz/km.

FIBER FACT: Fiber does not have the 100-meter (328-ft.) distance limitation of unshielded twisted pair copper (without a booster). Fiber distances depend on the style of cable, wavelength and network. Distances can range from 550 meters (984.2 ft.) for 10-Gbps multimode and up to 40 kilometers (24.8 mi.) for single-mode cable

At the end of the day, cost often causes us to choose an inferior product – but now, with the steady reduction in cost of fiber cable, components and hardware, it means we are now empowered to make the very best choice! As they say, 'goedkoop is duurkoop' – and the short-term investment in fiber means a much lower, long-term expenditure on maintenance, decreased downtime and less networking hardware.

Will you choose the speed of light?
