High density ODFK series for data centres More than half of the energy consumption of a data centre is related to the cooling of the data centre. Optimising consumption is directly related to optimising the volume to be cooled. For this reason, the market is tending towards more compact equipment, with the greatest number of connections in the smallest possible space. However, when designing a data centre, we must not forget the fundamental aspect of versatility. A design with a high density of connections but little flexibility is of little use. At Keynet, we have opted for totally modular systems that allow the installation of faceplates, cassettes, keystones…etc, in the same tray, optimising space and making it possible to easily make subsequent extensions or modifications. For this reason, we have developed a wide range of …

Network Termination Register (RTR Cabinets) for residential installations RTR-A This register is supplied in two parts so that the installer can imprison the frame during the wall plastering process. Later in the final phase of the work, the wooden panel with the equipment, the frame and the door will be mounted. This way the register is clean when the equipment is mounted. Main features: Reversible hinged door. Ventilation slots. Wall anchoring clips. Pre-marked side accesses for pipe entry. Depth adjustable frame favouring the final appearance. RTR-B Compact register with all the elements in a single piece. The door incorporates an anchorage to the structure that prevents accidental falls and damage to people or housing. Main features: Reversible door without hinge. Ventilation slots. Wall anchoring clips. Pre-marked side accesses for pipe entry. Door clamping element. Depth …

Foundations of the CPR Regulation In March 2011, the European Parliament published the Construction Products Regulation (CPR) as a Regulation. This regulation sets out the conditions for the marketing of construction products throughout the European Union. This regulation regulates all cables that are part of a construction, whether they are electrical, data, switchgear, fibre optics, etc. The member states have had to adapt their national regulations to bring them into line with the European CPR. Spain, in particular, and as far as cables are concerned, had to adapt the regulations on Common Telecommunications Installations (ICT) and the Low Voltage Regulation. One of the fundamental aspects of the CPR is the exhaustive regulation of the behaviour of materials in the event of fire. Cables are no exception. The CPR divides cables according to their behaviour according …

The protection rating (IP) The protection rating (IP) of an enclosure is a two-digit code, of which the first digit is associated with protection against the ingress of solids (dust, insects, etc.) and the second digit is associated with protection against the ingress of water or other liquids. There is a reciently created 9K level that considers high-pressure water jets. It does not concern us at the moment. So when we see a requirement for an enclosure we find a two-digit IP, for example IP55. This means that no particles even smaller than 1 mm in size can enter and that no water can enter unless there is 12.5 litres/minute at high pressure, more than 3 minutes, etc. For example, if it rains a normal rain, no water can enter. And normally this is the …

10 Good practices in optical fibre installations Optical fibre is a data transmission medium that sends photoelectric pulses through a wire made of transparent glass or other plastic materials. These wires can be as thin as a hair, and are precisely the signal transmission medium. Through these very fine wires, a light signal is transferred from one end of the wire to the other. This light can be generated by a laser or an LED, and its most widespread use is to transport data over long distances, as this medium has a much wider bandwidth than metallic cables, lower losses and higher transmission speeds. Optical fibre is reliable, safe, light and cheap. It has many advantages over any other transmission systems. But you need to always keep this list of good practices in mind. 1.- …
