Fibre Optic Distribution Cable
Fibre Optic Distribution Cable
Scandent with our World Class partner supplies a comprehensive range of fibre optic cables, manufactured in accordance with a number of international standards, and covering a wide range of applications for both indoor and outdoor installations.
Fibre optic cables consist of glass threads, each capable of transmitting digital data modulated into light waves. They effectively send information coded in a beam of light through a glass or plastic pipe. A key advantage of fibre optic cables over metal conductor cables is their superior performance in terms of bandwidth and therefore data carrying performance. Optical fibre cables are generally lighter and less susceptible to electromagnetic interference, however optical fibre tends to be more fragile than cables with a metal conductor.
OPTICAL FIBRE TYPES – SINGLEMODE / MULTIMODE
|
Single-mode optical fibre |
This is the simplest form of fibre optic cable in which all signals travel down the middle of the fibre without reflection. Single-mode optical fibre is suitable for data transmission over long distances (>100km) and it tends to be used for cable TV, internet, and telephone signals. Single-mode fibres have a very thin core of c.8-10 microns and are layed up together into bundles. |
|
Multi-mode optical fibre |
Multi-mode optical fibres are about 10 times bigger than single-mode fibres, which allows light beams to travel following a variety of paths (or multiple modes). These are suitable for data transmission over relatively short distances (maximum 2km) and tend to be used in computer networks. |
Optical fibres are classified according to their modal type and transmission speeds:
|
OM1 |
Multimode 62.5/125 |
|
OM2 |
Multimode 50/125 1 Gigabit |
|
OM3 |
Multimode 50/125 10-Gigabit |
|
OM4 |
Multimode 50/125 40-Gigabit |
|
OS2 |
Singlemode 9/125 (also known as 8/125 and 10/125) |
