Deep Dive: PoE Extenders, Repeaters

Deep Dive: Power over Ethernet Switches

PoE Switches - what are they, when to use them, what to know about them, and when not to use them. Power over Ethernet is a valuable technology that provides significant benefits for modern networking, including simplified installations, reduced wiring costs, and enhanced flexibility in device placement. The development of new standards, such as 802.3bt, is expanding the range of applications. Choosing the right PoE implementation (switch vs injector) and power class/standard for your needs requires a proper understanding of the technology's capabilities and limitations. Careful planning is necessary to ensure adequate power delivery and to mitigate potential issues associated with a central point of failure.

Deep Dive: Ethernet Cables (Cat6, Cat6 and Cat8)

This guide shows the different categories, including Cat6 and Cat8 cables and provides an overview over the different types of shielding.

Deep Dive: Self Healing Networks with PoE

This technology is referred to as PD Alive Check, PD Device Alive Check, Powered Device Monitor or PoE Watchdog. At the core of each, regardless of the specifics of the implementation by different switch manufacturers and chipset vendors, is the same basic function: Monitor connected PoE devices and, if they stop responding, power cycle the PoE device by briefly cutting power to it and forcing it to restart. After the restart, the PoE device will function again without the intervention of the network technician.

Deep Dive: Fiber Optic Cables

In the realm of computer networks, connections between various devices are predominantly established using two types of network cables. Copper-based network patch cables are primarily utilized for shorter connections, extending up to 328 feet (100 meters). These cables facilitate connections between computers and network switches or routers, link wireless access points to the network, or establish an uplink from one network switch to another. However, for connections exceeding 100 meters, a different type of cable is required: the optical-fiber cable. This guide discusses the fundamentals of fiber optic patch cables, also known as fiber optic jumper cables.

Deep Dive: PoE Extenders, Repeaters

A Power over Ethernet (PoE) extender is a device designed to amplify the reach of PoE networks beyond the standard 100-meter limit of Ethernet cables. By allowing both power and data to travel over a single cable, it enables the connection of devices like IP cameras and wireless access points in remote locations where power outlets are scarce. The extender boosts the signal and power, ensuring reliable performance without the need for additional wiring, making it an efficient solution for expanding network coverage in large spaces or challenging environments.
