With advancing standards, Power over Ethernet (PoE) will enable a whole new class of sophisticated devices which will require higher levels of power than ever before.
PoE has been an established technology for many years, powering everything from VOIP phones to wireless access points (WAPs) at relatively low power levels of less than 60 watts. With the IEEE 802.3.bt standard expected to be ratified in 2018, up to 100 watts will be possible. This advance will allow you to power stronger WAPs, more sophisticated closed-circuit TVs with pan/tilt/zoom capabilities and even large-screen 4K HDTVs on your category cable infrastructure.
Cable choice matters in high-power PoE applications. GenSPEED® Brand’s LP listed cables can handle the heat!
It is important to understand how your cabling infrastructure will perform under the higher power levels 802.3.bt will allow. Factors such as copper gauge size, cable design, bundle size and installation environment all impact a cable’s ability to handle heat rise generated from high-power PoE applications. General Cable’s GenSPEED line of category cables were the industry’s first to achieve UL’s LP listing, an independent verification that they will operate at power levels above 100 watts without exceeding the temperature rating of the cable. An LP rating provides assurance that a cable can handle the heat, no matter the bundle size or installation conditions. See the reverse side of this handout for a complete list of GenSPEED’s LP listed cables, rated from LP-0.5A (100 watts) up to LP-0.7A (140 watts). Continue reading
