A PoE switch delivers power and data to other network devices over one Ethernet cable. How you choose a suitable PoE switch is greatly dependent on your telecommunication network needs. An unmanaged PoE switch provides the most basic function of enabling connected networks to communicate, whereas a managed switch provides the same function as an unmanaged switch while allowing for better control of settings. You should also consider the port density. For example, the 8-Port Gigabit PoE Switch may be sufficient for small networks, while a high-performance 24-port Gigabit Industrial Ethernet Switch may be more suitable for businesses that need to support a vast amount of network devices.
