Power over Ethernet (POE) is a technology that allows for the transfer of power and data over the same Ethernet cable. This technology has been around since the early 2000s. The technology now includes a new standard known as 802.3bt. This new standard offers a number of benefits to organizations looking to implement POE.
More Power Over Longer Distances with 802.3bt
One of the main advantages of 802.3bt is an increase in power delivery over longer distances. With previous iterations of POE, it was only possible to deliver up to 30 watts of power per port at distances up to 100 meters when using Category 5e cables or higher. However, with 802.3bt it is now possible to deliver up to 90 watts at 100 meters over Category 6A cables, or up to 60 watts with Category 5e cables at the same distance.
This increase in power delivery can be useful for applications such as IP surveillance cameras which require more than 30 watts of power and are located further away from the network switch than usual due to space limitations or other factors. With 802.3bt, network switches can power directly the end points without having to rely on additional external power sources such as PoE injectors which add complexity and cost.
Higher Efficiency & Lower Costs
802.3bt has better efficiency compared with earlier versions of POE standards such as 802.3af and 802 3at. It uses ‘in-line’ topology where each port delivers its own dedicated supply voltage. It means that if there are 10 ports then there are 10 separate voltages being delivered simultaneously. This is regardless of whether all ports are active or not and how much current they require for operation at any given time.
The new standard uses ‘integrated circuit’ topology where multiple ports share a single supply voltage. Only one voltage needs to be delivered regardless of how many ports are active or not. This leads to increased efficiency, lower costs and reduced heat dissipation levels. The overall operation compared with in-line topology POE standards needs less current.
In conclusion, Power Over Ethernet (POE) has recently been updated with new standards known as 802 3bt. It offers a number of benefits such as an increase in power delivery over longer distances, higher efficiency compared with earlier versions. 802.3bt also brings costs down due to reduced heat dissipation levels thanks to its integrated circuit topology design structure. These features make 802 3bt an ideal choice for organizations looking for reliable, cost-effective solutions when implementing POE into their networks without sacrificing performance or reliability while still adhering to industry regulations and safety measures regarding proper electrical wiring procedures & practices by qualified personnel certified by local authorities and governing bodies where applicable according law & regulation(s).
