Fibre Optic Services

An Optical Fibre is a very thin strand of very pure glass which is used to transmit light signals across large distances and at high speeds. There are different types of fibres for different applications, for example some fibres are designed to carry a single light signal at a particular wavelength whilst others are designed to carry multiple signals simultaneously.

Due to the fine construction of the fibre it is very flexible, but also quite delicate and is therefore typically surrounded by a transparent cladding. However, light signals from the core cannot escape into the cladding because of the special refractive nature of the core. The whole fibre is further protected by an outer sheath known as a buffer and often there is a secondary coating which protects the fibre.

The use of optical fibres and the associated electronics to carry communications signals between receivers and transmitters is known as Fibre Optics

Why Fibre Optics?
Fibre Optic technology is typically employed in applications where a traditional electrical solution is impractical. The signal transmitted within the Fibre Optic system suffers from far less attenuation than the equivalent electrical system and can therefore travel much greater distances. A single fibre is able to transmit over distances in excess of 10km. Also, the data transmission speed which can be achieved with Fibre Optics is far greater. Data rates of 1, 10 or 40 Gbit/s are common, but rates in excess of 100Gbit/s have been reliably implemented. These superior data rates mean that a single fibre can carry the equivalent of more than 12 copper Cat.6 Ethernet cables.

Another feature of Fibre Optics is its immunity to electromagnetic noise. A traditional electrical signal cable must be screened and routed so as to physically avoid sources of electromagnetic noise (such as inverter drives, transformers etc) since the signal can become corrupted by interference. Since Fibre Optic systems employ non-conducting fibre and transmit light, electromagnetic noise is not a concern. Furthermore, since the fibre is non-conducting it is suitable in external applications which may be susceptible to lightning strikes.

As an emerging technology, Fibre Optics was considerably more expensive than the existing electrical signalling systems. Having now become an established technology, Fibre Optics can offer significant savings on applications which require larger distances and higher reliability.

Saftronics Fibre Optics Services
Fibre Optic installations should be designed, terminated and validated in accordance with specified criteria in order to give the most optimum and reliable performance. Having been at the forefront of innovation in Industrial Communications for decades, Saftronics has gained a wealth of knowledge and experience which has proven essential in supplying reliable systems to our customers.

Whether your application is for an Ethernet, fieldbus or other network, Saftronics can design, terminate and test the Fibre Optic installation including any requirements for transceivers, repeaters, instrumentation and patch panels to meet all of your requirements and specifications.

Our trained and qualified engineers can assist you with selection of the most suitable components, planning the route of the Fibre Optic cables and tailor the design to provide a fully maintainable network. Once the network has been installed and terminated we will perform the necessary tests to ensure the fibre is operating at its optimum.

Optical Time Domain Reflectometer (ODTR) tests ensure that there is minimal light loss (attenuation) at each connection. Wavelength results will be fully detailed within our report upon completion of testing. These results show the length of each fibre and can indicate any bends in the core. This information can be useful for network diagnostic at a later date and, for example as part of an annual maintenance check.
