More devices than ever are converging onto a common IT infrastructure, allowing low-voltage building systems like voice, data, security, AV, lighting and HVAC to communicate with each other via Internet Protocol (IP) to provide significant cost savings and sustainability over the life of the facility, while improving overall user experience, wellbeing and productivity.
The foundation to this integration is a single unified physical infrastructure that transmits information and delivers power to devices using Power over Ethernet (PoE) technology – everything from IP phones, desktop computers and wireless access points, to surveillance cameras, LED lighting, distributed antenna systems and building automation devices. The benefits that remote powering delivers; faster deployment, 75% less cost than an AC power run and the ability to receive centralised back-up power, just to name a few, has seen an dramatic increase in the number of PoE devices in use.
The first generation of PoE, IEEE 802.3af Type 1 (15W), was used for powering lower-power devices like IP clocks, VoIP phones and simple security cameras. With the development of IEEE 802.3at Type 2 (30W), higher level IEEE 802.3bt Type 3 (60W) and Type 4 (90W), and POH (100W) for AV applications, remote powering technology now powers everything from wireless access points, advanced pan-tilt-zoom cameras, access control devices and LED lights, to video displays, point of sale machines and even computers and laptops.
The ability to deliver DC power to IP-based devices over twisted-pair copper cabling using remote powering technology like Power over Ethernet (PoE) and Power over HDBaseT (POH) has made a significant impact on today’s network infrastructure deployments.
With increased levels of remote powering comes the potential for heat build-up within cable bundles and electrical arcing damage to connector contacts. This can lead to power and efficiency losses, performance degradation and the potential for damaged connecting hardware. Choosing the right cabling infrastructure for networks that deliver remote power is vitally important. Category 6A shielded and Category 7A fully-shielded cables with PowerGUARD technology are qualified for mechanical reliability in high temperature environments up to 75° C, ensuring superior heat dissipation and extremely stable transmission performance, enabling decreased length de-rating as shown in the graph and reduced bundling requirements.
