News 050.7374 050.7375 050.7376 The R&M HEC connectors work reliably in any extreme environment, for example in freeway tunnels, satellite dishes or wind turbines. This is Where HEC-BR and HEC-QR Work The new outdoor connectors from R&M won’t have to look hard to find a place to work. They will be in demand in all kinds of places – for example at the next corner end. Telecom companies are currently connecting entire cities, countries, transport routes and locations with 5G small cells. 5G antennas are installed every few hundred meters. They need connections to fiber optic networks. The fiber optic connections on masts and on The strengths of HEC-BR and HEC-QR: – Telcordia GR 3120 and IEC 61753-1 are met – Protection class IP68 – Temperature stable -40 °C to +85 °C – Tensile load up to 450 N – HEC-QR is the smallest connector of its kind 030.8319 buildings have to withstand all weathers. At the same time, they also have to be easy to operate in any situation. This is why R&M has designed the robust HEC pair in such a way that the housing can be mated by someone without a direct view who is wearing gloves and working one-handed. The end faces of the fibers cannot be soiled or scratched. HEC stands for Harsh Environment Connector. The two connector variants from R&M will work reliably in any extreme environment. Areas of application include wind and solar parks, which are constantly subjected to the weather. The alternative power plants require stable fiber optic connections to data networks so that information about the available power can be accessed in real time. Wide range of applications Operators of roads, tunnels and railway lines are also making increasing use of fiber optic cabling. Their infrastructures are perfect for expanding data lines. The cables, enclosures and connectors are also exposed to significant environmental impacts: moisture, salt mist, dust, vibrations. This is exactly where HEC-BR and HEC-QR come into their own. At events, large volumes of data and high-resolution live streams are produced for the Internet. Fiber optic cables are the ideal transport medium. When setting up and dismantling events, cables and connectors are exposed to considerable mechanical loads. No problem for HEC-BR and HEC-QR! Other similar areas where they can be put to good use include mining, oil fields, industrial facilities, container ports, as well as research and satellite stations. When laying above-ground cables for the FTTH supply, it is often a matter of also being able to install unusual connections as simply and cost-effectively as possible. Aerial solutions from R&M can be used here – including HEC-BR and HEC-QR. 050.7310 HEC-BR (Bayonet Release) and HEC-QR (Quick Release) are easy to install, even in harsh environments.

News Vital Signs under Control 050.7377 Data centers are a prerequisite for digitalization and have a major impact on economic development. To ensure that they always function smoothly, it is essential to measure the ambient conditions correctly with the right sensors. A key component is the intelligent PDU. The sensors make it possible to monitor various parameters, such as energy consumption, temperature, humidity and access security. This enables administrators to identify potential problems and take appropriate corrective measures at an early stage. The intelligent ActiPower 4.0 Power Distribution Unit (PDU) Intelligent ActiPower 4.0 PDU from R&M 050.7378 from R&M offers efficient integration. The connection to the network means that all sensor data can be displayed and monitored on the web interface. Real-time monitoring of energy consumption is of fundamental importance when it comes to planning how the racks are to be equipped with servers. This is because overloading the power line can lead to significant problems and, for example, cause failures or safety risks. This is why measuring the energy consumption in each rack using smart PDUs has become established in the industry. Critical threshold values can be detected and alarms triggered if need be. This may be the case, for example, when a rack is expanded to include additional active servers. Indispensable for safe operation Servers not only need sufficient power but also an optimum operating temperature and humidity to be able to work efficiently. This is where temperature sensors such as the EMD31 come into play. These sensors record environmental temperature and humidity at specific points and are connected to the sensor socket of the ActiPower 4.0 PDU via an RJ45 cable. For added security and control, the EMD31 sensor allows the connection of two additional digital sensors. For example, a moisture sensor cable can be laid in the floor/raised floor in order to detect water leaks from cooling units in good time and prevent potential damage to the infrastructure. The security of the data center also plays a prominent role and access to sensitive areas must be strictly controlled. Among other things, door contact sensors are used to ensure that the lockable rack doors are properly closed after access. www.rdm.com/actipower- 4-0-smart-pdus-for-your-dc/ Andreas Klauser | Product Manager andreas.klauser@rdm.com 050.7244 10|2023–65 CONNECTIONS | 11
