Siemon, a leading global network infrastructure specialist, has announced that it has equipped its copper cables, outlets, plugs and patch cords with innovative PowerGUARDTM technology to ensure a robust and reliable end-to-end balanced twisted pair cabling system that guards against the impact of delivering DC power to IP-based devices over the low-voltage converged IT infrastructure within intelligent buildings.

Remote powering technology, like Power over Ethernet (PoE) and Power over HDBaseT (PoH) transmits DC power over copper twisted pair cabling to end devices such as wireless access points (WAPs), LED lights, video displays, digital signage and even desktop computers but when unmating these device connections under load, electrical arcing can damage connector contacts. This can lead to performance degradation and reduced connecting hardware reliability.

Siemon’s PowerGUARD technology includes patented crowned contacts on the company’s Z-MAX, MAX and TERA outlets that place the arcing damage away from the final mated position to ensure the integrity of contact seating surfaces and to maintain long-term reliability.
Remote power delivery also increases the temperature inside cable bundles which increases signal attenuation and premature ageing of jacketing materials. To combat the effects of heat build-up, Siemon has incorporated PowerGUARD technology into its Category 6A and 7A cables. These cables are qualified for mechanical reliability in high temperature environments up to 75°C and ensure superior heat dissipation and extremely stable transmission performance, whilst preventing the need to reduce link length and cable bundle size.

For networks that utilise modular plug terminated links to connect WAPs and other IP-based end devices directly to the network, Siemon’s Z-PLUG Category 6A field-terminated plug with PowerGUARD technology features a fully shielded 360-degree enclosure and 75°C operating temperature, providing superior heat dissipation in conjunction with Siemon PowerGUARD cables.

For traditional network deployments that utilise patch cords for connecting end devices to outlets, Siemon’s Z-MAX Category 6A and TERA Category 7A four-pair shielded solid modular cords with PowerGUARD technology also offer a 75°C operating temperature, reducing the potential for degraded transmission performance at elevated temperatures and making them ideal for use in spaces that do not have environmental control (e.g., ceilings and warehouses). For use within environmentally controlled spaces, such as active equipment and cross- connect connections within telecommunications spaces, Siemon Category 6A shielded stranded modular cords with PowerGUARD technology are also qualified to 75°C.

"With today’s higher levels of remote powering including IEEE 802.3bt 60W Type 3 and 90W Type4 PoE for networked devices and 100W PoH for HDBaseT AV devices comes a greater potential for heat build-up within cable bundles and electrical arcing damage to connector contacts," explains Prem Rodrigues, director for the Middle East, Africa & India/SAARC at Siemon. "By incorporating PowerGUARD technology into our cables and connectivity we are preventing both of these issues and so protect the network from power and efficiency losses, performance degradation and reduced connecting hardware reliability. At the same time, PowerGUARD prevents the need to apply more stringent bundling requirements and a de-rating of link lengths to maintain performance. As a result, our copper cabling and connectivity provides greater flexibility to those tasked with designing and installing networks."
