Power over Ethernet, or PoE, equipment and systems have been taking the networking world by storm – not just in information technology, but also in wireless access, video surveillance, access control, lighting control, and many other varied applications. The overall demand for network connectivity has been a primary driver, and using PoE provides specific advantages in terms of installation cost savings, system simplicity and flexibility, power management, and overall system reliability.
While the decision to implement the best PoE for networked systems is an easy one, a harder decision may well be how to evaluate the enormous offering of PoE equipment providers and their specific solutions.
Fortunately, PoE standards compliance is designed to ensure, to a great extent, device functionality and interoperability. This means that devices that have been tested and certified to meet PoE standards should function as described. The question then becomes how to ensure that your selection is based on the most important differences between providers, empowering you to make the best selection and purchase decisions.
Here are 6 key attributes to help guide your selection process:
PoE Selection Factors
Factor 1: Support for Maximum Power
As support and enthusiasm for PoE applications has grown, so has the number of devices that are PoE-capable. PoE systems are limited by their maximum wattage specifications. The available power determines what devices can be used in your system, and how many can be used with each cable connection. In general, higher power ratings provide you more options both in terms of what devices you can use, and in how many cables will be needed to support your desired PoE equipment.
Over time, the power specifications have only gone up, so the last thing you would want to do now is to install a system that has a less-than maximum power rating. DITEK PoE solutions, for example, feature IEEE 802.3bt support for high PoE power – giving your system maximum flexibility and longevity.
Factor 2: Support for Maximum Distances
PoE specifications set the maximum cable distance that can be guaranteed, which sets limits on system design and the placement of devices and connections. Some PoE solutions are designed so that PoE extenders have the capability to be connected in a cascading fashion – that is, allowing the use of more than one PoE extender to support much longer cable runs.
The ability to support longer cable runs may have a direct effect on your system design and deployment. If longer runs aren’t needed now, having the ability to add extended runs is a future-proofing factor that should be considered at the outset. Check out DITEK PoE extenders – with support for cascading to maximize cable lengths.
Factor 3: High Environmental Tolerance
PoE solutions for outdoor installations should be designed for weather resistance. Ingress protection, or IP ratings, are specified in IEC standards, and are the industry-standard way to convey the degree to which PoE devices are protected from intrusion by foreign bodies such as tools, dirt, and moisture. DITEK PoE products are designed with environmental resistance in mind. For example, the DTK-EXTO Extender is IP65 rated to be waterproof and dust tight for harsh outdoor applications.
While outdoor use has clear requirements, many interior installation locations, such as factory floors, benefit by the use of environmentally-resistant products to prevent accidental damage from liquid sprays, dusty environments, and similar hazards.

Factor 4: Potential for Bundling
One often-overlooked factor in PoE system installations is the need to protect against damaging electrical surges and spikes. Because DITEK has industry-leading expertise and products designed for the protection of network devices, DITEK is in a unique position to bundle PoE solutions with surge-protective devices for a complete project solution package.
Factor 5: High Reliability
Meeting the PoE specification is one thing – providing reliable, long lasting network service is another. One good evaluation factor to include in your considerations is the length and quality of the PoE equipment warranty. A substantial warranty, offered by a well-established and well-respected company, is a strong indicator of the reliability that you can expect from the equipment.

Factor 6: Price
Last but not least – price is always a factor in the context of overall value. When you look at all the factors, consider the overall price along with the longevity, flexibility, reliability, and capabilities of the provider and the equipment. That approach will lead you to the right selection for your project!
