Just What Is IEEE802.3bt PoE++ And How Does It Affect The Type Of Cable You Use?
Power over Ethernet has been around for quite a while now, with the IEEE standardizing it back in 2003. PoE lets network equipment draw power from the data cable that’s also used for Ethernet communications. This is handy if you want to deploy devices in locations where there’s no power outlet, or you want to avoid the cost and mess of running new power cables. The latest version of the PoE standard is 802.3bt, which was ratified in late 2018. This standard defines new requirements for PoE-powered devices and the cabling used to connect them. In this blog post, we’ll take a look at what’s new in 802.3bt and how it affects the type of cable you use for Power over Ethernet applications.
What is IEEE802.3bt PoE++?
IEEE802.3bt PoE++ is the latest standard for Power over Ethernet, and it offers a few advantages over the previous 802.3af and 802.3at standards. For one, it increases the maximum power delivery from 60 watts to 90 watts, which is enough to power devices like 4K TVs and monitors, as well as high-powered WiFi access points. It also allows for two-pair or four-pair cabling, which means that you can use thinner and more flexible cables than before. Finally, it’s backward-compatible with older PoE equipment, so you don’t have to replace all of your existing gear to take advantage of the new standard.
What type of cable do you need for IEEE802.3bt PoE++?
IEEE802.3bt PoE++ is the latest version of the IEEE PoE standard and provides up to 100W of power over Ethernet cables. This means that you can now use thicker, higher-quality cables for your PoE++ devices without worrying about losing power or data transfer speeds. When choosing a cable for your IEEE802.3bt PoE++ devices, make sure to pick one that is compatible with the voltage and current requirements of your equipment.
Are there any drawbacks to using this standard?
Yes, there are some drawbacks to using the IEEE.bt PoE++ standard. One is that it requires a specialized cable called an Ethernet cable, which can be difficult to find in stores. Another drawback is that it doesn’t work with all types of devices, so you may need to buy a separate adapter if you want to use this standard with your device.
Conclusion
In conclusion, IEEE802.3bt PoE++ is a new standard for Power over Ethernet that offers increased power delivery and supports new cable types. When choosing a cable for your PoE application, it is important to consider the voltage and amperage requirements of your device as well as the length of the cable run. For runs longer than 100 meters, you will need to use a shielded twisted pair cable with an appropriate gauge to minimize resistance and ensure safe operation.
