Fibre Optic Cables

Eland Cables supplies a comprehensive range of fibre optic cables, manufactured in accordance with a number of international standards including IEC 60332-1, 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.

Applications for fibre optic cables range from carrying telephone calls (up to several million calls per cable) to high speed data transfer for vast computer networks.

Optical Fibre and Fibre cable selection

The type of optical fibre is dictated by the application,the distance which the signals are required to travel, and the speed of transmission. The cable construction is then chosen according to the installation's environmental requirements which can range from indoors within a dry wall in a public area requiring low smoke zero halogen (LSZH) materials, to outdoor trackside by a railway network. For mission-critical applications, all of our fibre optic cables are also available in fire resistant (IEC 60331) versions on request.

Eland Cables has extensive experience in the specification of fibre optic cables. Our technical engineers also work with customers, including Network Rail in the United Kingdom, in order to develop new cable constructions for optimal performance, such as the fibre trackside cable. Please contact us to discuss your application and specific project requirements.

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)

Available standard fibre optic cable construction types:

LTU Loose tube unarmoured optical fibre cable
LTT Loose tube steel tape armoured optical fibre cable
LTW Loose tube steel wire armoured optical fibre cable
TBU Tight buffered unarmoured optical fibre cable
MTU Multi-loose tube unarmoured optical fibre cable
MTT Multi-loose tube steel tape armoured optical fibre cable
MTW Multi-loose tube steel wire armoured optical fibre cable

Fire resistant (IEC 60331) designs for all cable construction types are available on request.
