The growth of IP-connected network devices throughout organizations has fueled the demand for faster data speeds and the need for greater power consumption. This created a need for a system to keep up with the larger power consumption without losing connection quality or speed. Plus, the solution needed to be affordable for the average consumer.
This requirement has paved the way for the widespread use of Power over Ethernet (PoE).
What is Power over Ethernet?
Power over Ethernet (PoE) is a method for transmitting electric power and bandwidth to external servers in a sensible way, utilizing conventional Ethernet cabling of Category 3 or above classification. For PoE to work, you must convert the primary power source into a low-voltage supply, and the electricity must then get transmitted over cables to the devices supporting PoE.
When data and power signals are transmitted simultaneously, the mechanism prevents interference. Power gets conveyed over the data conductors by delivering the same power to each pair of data wires. Although twisted-pair Ethernet employs differential transmission, this will not interfere with data transfer. Power over Ethernet can transmit both data and power communications without interfering with the data signal.
Power over Ethernet has steadily and cautiously gained a place in the ITC network by demonstrating its reliability and efficiency. Power over Ethernet solutions initially merged data and electricity into a single connection, delivering up to 12.4 watts for every device. Power over Ethernet systems can offer up to 90 W, sufficient for supplying the latest and most energy-consuming devices.
Through Power over Ethernet, several connected devices can integrate data and power connections across a single copper Ethernet cable, simplifying the network, easing processes, and increasing the number of devices that can be supported on a single cable. However, Power over Ethernet’s potential to supply more devices is only one aspect of a larger story.
Selecting PoE Cabling
Since its introduction, Power over Ethernet has become a critical power-supplying approach. It enables network administrators, distributors, and designers to simultaneously employ structured cabling that provides power and data to numerous network devices. Its ability to manage reduced power and data across the same connection can considerably ease PoE networks’ implementation and operation.
Engineers must consider several essential aspects that determine and drive a PoE’s efficient management and implementation.
- Maintaining channel topology or the infrastructure of the cable route
- Optimizing thermal loads through cable bundling, positioning, and length of cables
- Choosing cables, cords, and connections with care
Using a Universal Connectivity Grid
Devices will require significant network access and cabling to function properly. Using a Universal Connectivity Grid, one can link any person, system, and device in a facility, whether stationary or on the road, in the least intrusive way imaginable. This type of infrastructure is built to accommodate all information technology services in a centralized location with a clean and ordered architecture.
In a typical network cabling layout, Power over Ethernet ports are connected directly to the access point in the floor’s telecommunications room through horizontal cables. Many setups employing four-pair PoE, particularly new deployments, might benefit from a cabling method known as the Universal Connectivity Grid, which allows for easier cable layout and increased flexibility in deployment.
Moreover, when using a Universal Connectivity Grid, one may establish cable connectivity throughout a workplace by integrating functionality and efficiency to ensure that the space can manage the demands of users ramping up or down.
Category 6A Cabling
When considering your cabling infrastructure, future-proofing your cabling is also important. Category 6A cabling is recognized throughout the industry as the cable category of the future. This reputation permits the next-generation implementation of high-bandwidth copper communication. When preparing today’s modern facilities for current and future uses, Category 6A provides the most cost-effective and straightforward setup.
With the emergence of 10-gigabit applications, the time has come to think about equipping the facility with the appropriate copper cabling infrastructure based on Category 6A twisted pair networking to support these applications. As a result, cabling companies rushed to imitate it as soon as possible, and standards organizations were forced to establish a consensus.
The Benefits of Power over Ethernet through Category 6A Cabling
Below are some benefits of power over ethernet used through Category 6A cabling.
- Because Category 6A cabling made power over ethernet possible, it became particularly well suited as a foundation for a new generation of technologies, applications, and functions.
- Apart from supporting 10 Gbps speeds, Category 6A cabling also significantly enhanced the ability of device makers to deliver higher power and available bandwidth wherever, with no location restrictions apart from the peak stream length of 100 m, because devices can be positioned anywhere within the scope of a PoE switch rather than an AC outlet.
- Category 6A cabling allows for a better thermal cooling performance than its Category 5E and Category 6 predecessors. It is particularly important as the Power over Ethernet standards are getting revised to increase the amount of power delivered to devices that use all four pairs of the connection.
- As four-pair power over ethernet will be close to 100 watts, you will realize enhanced thermal efficiency for PoE. Furthermore, the significant benefits of using a single channel for both power and data are propelling the proliferation of power over ethernet-powered devices.
It is necessary to ensure compliance with the numerous cabling standards. It is highly encouraged to use Category 6A for new construction. The criteria abide by TIA TSB 162 for Wi-Fi, TSB 184-A for power over ethernet, TIA 1179 for healthcare, and TIA 4966 for education.
As more probes and control systems get implemented, both inside buildings and beyond, the importance of power over ethernet should continue to grow. Implementing power over ethernet together with Category 6A cabling is of great help in keeping connections safe and stable.
