Fibre Optic

We provide a range of services, such as fusion splicing, single-mode and multi-mode cable installation and testing.

Fibre optics can solve many data communications problems. Although it may not always be practical to use fibre in every situation, such as to transmitting data between a PC and printer, there are a number of advantages that should be considered.

Noise/Interference
As copper conductors (CAT5/CAT6) carry electrical signals, they are subject to interference from the surrounding environment such as electro magnetic fields given off from electrical cables, lights, motors, etc. These fields induce currents in the conductor causing interference. As fibre optics are made of glass fibre and transmit data via light signals, they are not subject to interference.

Security
Electro Magnetic Field induction works both ways. The signals transmitted in copper data cables also have magnetic fields that can leak data. Fibre optics are not subject to these leaks as there is no EMF.

Bandwidth
Copper cables can transmit data up to a maximum distance of 90m. Fibre optics have the capacity to transmit very high speed signals over much greater distances without the need for repeaters.

Cables

Single Mode cable is a single stand of glass fiber with a diameter of 8.3 to 10 microns that has one mode of transmission. Single Mode Fiber with a relatively narrow diameter, through which only one mode will propagate typically 1310 or 1550nm. Carries higher bandwidth than multimode fiber, but requires a light source with a narrow spectral width.

Synonyms mono-mode optical fiber, single-mode fiber, single-mode optical waveguide,uni-mode fiber.

• Single-mode fiber gives you a higher transmission rate and up to 50 times more distance than multimode. Single-mode fiber has a much smaller core than multimode. The small core and single light-wave virtually eliminate any distortion that could result from overlapping light pulses, providing the least signal attenuation and the highest transmission speeds of any fiber cable type.
• Single-mode optical fiber is an optical fiber in which only the lowest order bound mode can propagate at the wavelength of interest typically 1300 to 1320nm.
• Single-mode fiber will be useful for distances well in excess of 10 miles but will require the use of single-mode transmitters (which normally use solid-state laser diodes).

Multimode cable is made of of glass fibers, with a common diameters in the 50-to-100 micron range for the light carry component (the most common size is 62.5). POF is a newer plastic-based cable which promises performance similar to glass cable on very short runs, but at a lower cost.

Multimode fiber gives you high bandwidth at high speeds over medium distances. Light waves are dispersed into numerous paths, or modes, as they travel through the cable’s core typically 850 or 1300nm. Typical multimode fiber core diameters are 50, 62.5, and 100 micrometers. However, in long cable runs (greater than 3000 feet [914.4 m), multiple paths of light can cause signal distortion at the receiving end, resulting in an unclear and incomplete data transmission.
