When installing a network, one of the first things users consider is whether to use fiber optic cable or copper cable. Although both copper cable and fiber optic cable can transmit an acceptable signal, fiber optic cable is the most desired choice with today’s growing bandwidth requirements over long distances. This article will share eight reasons why users should choose fiber optic cable over copper cable.

The internet of things (IoT) is rapidly becoming a reality, with more and more devices connecting to the
internet every day. But as the number of devices grows, so does the challenge of managing them all.
That’s where the Power over Ethernet (PoE) switch comes in. PoE switch provides power and data to
devices over a single connection. This article will help you understand PoE Switch.
What is a PoE Switch?
A PoE switch is a device that combines the functionality of a switch and a power source in one. It
has multiple Ethernet ports that can be used to connect other devices, such as VoIP phones,
wireless access points, and IP cameras. The switch is responsible for providing power to the
connected devices, eliminating the need for separate power cables.

The technology behind the PoE switch is known as power over ethernet switches. PoE is a
technology that enables the transmission of both data and electrical power over Ethernet cables.
It uses a combination of a power source and power injectors to send power to connected devices.
Power injectors act as a bridge between the power source and the connected devices. And they
are responsible for the transmission of both data and power.
Types of PoE Switch
There are three main types of PoE switches.
 An unmanaged PoE switch is easy to use and simple to configure. It is ideal for applications
that do not require complex network configurations.
 Managed PoE switch is more complex and has many configuration procedures. It is ideal for
applications that require more control over the network, such as VLANs, QoS, port mirroring,
and port security.
 A smart PoE switch is a very advanced switch that provides multiple functions. It is ideal for
applications requiring detailed network configuration and monitoring.

Benefits of Using PoE Switches
PoE switch brings benefits over the following aspects:
 Simplicity: PoE switch is easy to install and configure, plug-and-play. It also comes with
built-in features such as port mirroring, VLANs, and QoS, which can help to streamline
network management.
 Cost-Efficiency: PoE switch provides the necessary power for each connected device,
eliminating the need for an oversized power supply, which helps to reduce energy costs and
can result in long-term savings.
 Flexibility: Devices powered by PoE are simple to move to areas without power outlets.
Because of this, devices can be placed in places that are difficult to reach or less close to a
power source. IP cameras are one example of this, as power outlets are rarely found above
ceilings.
 Future Application: The IoT industry is booming. Incorporating PoE switch into your network
infrastructure ensures it can support the increasing number of devices optimized to leverage
this technology.
