Draka releases guide to bend insensitive fibres D
raka, a brand of Prysmian Group, is pleased to announce the arrival of a comprehensive new technology guide: ‘Bend-Insensitive
Bend-insensitive single mode fibres (ITU-T G.657.A1 and G.657.A2) are the only fibres capable of securing the whole fibre spectrum, especially at the longer wavelengths (1625 nm and above), by minimising losses linked to macro and micro bends. These fibres enable the development of extreme fibre count and reduced diameter cabling solutions, to help meet today’s demand for the highest bandwidth capacity in duct installations. Each fibre optic cable within the Draka
Universal Cabling System comes in a range of bend-insensitive fibres, manufactured in Draka’s European factories, that provide the necessary standard of cable density, and support the necessary fibre spectrum demanded by new PON technologies. BendBright fibres support the full use of transmission bands, covering the entire wavelength spectrum, from 1260 nm to 1625 nm for data transmission, and up to 1675 nm for network monitoring.
The new Draka Bend-Insensitive Fibres
guide looks at the evolution of network systems and puts the case for bend insensitive fibre - in particular, G.657.A2 - as being the unique answer to securing future systems, enabling the most potential to be gained from deployed networks. The guide provides a brief explanation
of the types of bend-insensitivity before moving on to look at the latest developments in fibre coatings which virtually erase problems associated with bending, whilst also significantly reducing cable diameters and achieving high fibre density. A key focus of the guide is on the range of
benefits bend-insensitive fibres bring. For manufacturers, and ultimately customers, bend- insensitive fibres provide a greater scope for product design and cabling solutions. For installers, installation is easier and smaller connectivity devices can be used to save space. For network owners, using bend-insensitive fibre
has considerable financial benefits, with optimised total cost of ownership and OPEX savings as a result of easier installation and robustness. Ultimately, latest generation bend-insensitive fibres help future-proof higher capacity networks.

ENSURING CABLE STANDARDS

Check approval for Category 3 Control fire performance cables, warns AEI Cables “We should point out that anything inferior
pecialist AEI Cables is highlighting the need to use only approved cabling in critical signal and control equipment in the event of
a real fire with the announcement of a revised version of the Code of Practice covering these areas of performance. The equipment served by these cables - including
smoke and heat extraction systems - assists fire services in the case of firefighting and a safe evacuation in the case of life safety. As the only supplier in the UK with independent
approval from LPCB for BS8519 Category 3 Control fire performance cables with a fire survival time of up to 120 minutes, AEI Cables is highlighting the reference in the new revised version of the standard. Graham Turner of AEI Cables, says: “The standard
clearly references and clarifies the products and levels of performance that should be used for all parts of the supply chain from specifiers to contractors and installers.
installed is dangerous and could lead to some of these systems simply not surviving in a fire with the dangers that brings. These cables reduce the risk to life through the reduction of harmful smoke, toxic gases, and reduced flame spread. We should all strive to achieve the highest performance possible. “Fire and rescue services depend on these
systems to help fighting a fire and the safe evacuation of those who may be in the building – installing the wrong products can be catastrophic.” The applications of Category 3 Control fire
performance cables also applies to evacuation alarms for the disabled in care homes, emergency voice communications systems and voice alarm systems in relevant buildings including tall buildings, office spaces, hospitals, care homes, shopping malls and stadia. AEI Cables’ Firetec Enhanced cabling has been approved and certified by LPCB to BS8519

(Annex B), Category 3 Control in addition to Category 2 Control. The BS Code of Practice under BS8519 contains six categories of cables, three for power cables and three for control cables each covering survival times of 30, 60 or 120 minutes. Using the very latest in technology and science,
the Firetec Total Fire Solutions range offers Mineral Insulated Cabling (MIC), Firetec Enhanced fire performance cabling, accessories and technical support from the AEI Cables distribution facility at Washington, Tyne and Wear. All AEI Cables’ products are supplied with
approvals from independent bodies including BASEC and LPCB. It also holds approvals from organisations including Lloyds, the MoD, Network Rail and LUL and works to international standards around the world.
