Power over Ethernet (PoE) is a technology that allows a network to send electrical power over standard Ethernet cables. The technology was developed to make installation of new devices easier and to reduce the amount of electrical wiring that is required. In particular, PoE reduces the amount of wiring required for IP phones, wireless access points, and cameras, which often require power but may not be close enough to a power outlet to plug in. PoE is an important technology for networking in remote or difficult to access areas.

POE-48I-CI, which stands for Power over Ethernet - IEEE 802.3af and IEEE 802.3at Interconnect-Compliant Injector, is a PoE technology designed specifically for IP phones, wireless access points, and cameras. This technology is different from the standard Ethernet cable because it allows the user to inject and receive power through the network, eliminating the need for traditional electrical wiring. The POE-48I-CI injector is designed to automatically detect and adjust to different power levels, making it suitable for a wide range of networking and security applications. Therefore, the POE-48I-CI injector can be used in any networking application where PoE is needed.

The working principle of the POE-48I-CI injector is based on a physical layer protocol called the Power Delivery Layer (PDL). This protocol is responsible for providing power to network devices through the Ethernet cables. The injector contains two integrated power supply units (PSUs) which are controlled by the PDL. The first PSU is designed to inject power into the Ethernet cables while the second PSU receives power from the network. The PDL uses a cyclic redundancy check (CRC) to ensure that the power is correctly routed between the PSUs.

The POE-48I-CI injector can provide up to 48W of power to the network. This is enough power to support multiple PoE-enabled devices. The injector also supports IEEE 802.3af and IEEE 802.3at, which is the industry standard for Power over Ethernet. In addition, the injector also comes with support for 10/100/1000Mbps networks, making it suitable for a wide range of applications.

The POE-48I-CI injector is used in many different applications. It is particularly useful for IP phones, wireless access points, and cameras, as it eliminates the need for traditional electrical wiring. This makes it ideal for remote or difficult to access areas, such as warehouses and data centers. The injector is also suitable for any other network applications that require power over Ethernet, such as access control systems, video surveillance systems, and robotics.

In summary, the POE-48I-CI injector is a Power over Ethernet technology designed specifically for IP phones, wireless access points, and cameras. It works by using the Power Delivery Layer protocol to inject and receive power through the network, eliminating the need for traditional electrical wiring. The injector can provide up to 48W of power and supports IEEE 802.3af and IEEE 802.3at, making it suitable for a wide range of applications. Furthermore, the POE-48I-CI injector is especially useful in remote or difficult to access areas, such as warehouses and data centers.
