Ag6800 (PSE) and Ag5800 (PD) modules High power 4 pair POE compliant to IEEE802.3bt

Many Silvertel customers are aware that the IEEE has been in drafting a new Power over Ethernet standard, 802.3bt for some time. This is a new higher power standard for delivering a maximum power of anywhere between 71W and 100W at the PD (depending on losses and cable lengths), over the full 4 pairs of wires in a CAT5E cable to improve efficiency and minimise losses at the higher power levels. This standard is now at Draft 3.2, to which release level Silvertel are preparing a new set of modules, the Ag6800 and Ag5800. Ag6800 will be a fully (draft) standards compliant 95W maximum output PSE module and will be released first, followed shortly after by the Ag5800 PD module delivering up to 100W of usable power to the end device. Both modules will be cost and footprint size optimised to provide state of the art solutions at market leading prices for our customers for the next generation of POE applications.
