Surf the Internet in the early age — PPPoE technology

PPPoE represents a point-to-point protocol on the Ethernet. It is a network tunnel protocol that encapsulates the point-to-point protocol (PPP) in the Ethernet framework. It enables Ethernet hosts to connect to a remote access concentrator via a simple bridging device.Using PPPoE, remote access d... Read More

POE Power Supply Mode

POE power supply is achieved through the network cable, and the network cable is composed of four pairs of twisted pairs (8 core wires), so the eight core wires in the network cable are the PoE switch to provide data and power transmission media for the receiving device. At present, PoE switches ... Read More

Working Principles of PoE Switch

Step 1: Detect the receiving device (PD). It is mainly to detect whether the connected device is a real receiving device (PD) (in fact, it is to detect the receiving device that can support the Power over Ethernet standard). The PoE switch will output a small voltage at the port to detect the rec... Read More

POE Power Supply

Under the development trend of the Internet of everything to build a smart world of things, users’ demand for IoT devices is increasing, and POE switches have become an effective medium to provide power and data transmission for PD devices through network cables. PoE switches allow devices ... Read More

10G (100 Gigabit) Ethernet Technology and Application

With the deployment and implementation of the optical transformation of broadband network, the network quality is improved, the failure rate is reduced, and the user’s favorable impression is increased. At present, the formation of broadband access network is dominated by FTTH and supplemen... Read More

Functional Difference between access layer-Aggregation layer-Core layer switch

The core layer switch is mainly used for route selection and high-speed forwarding, providing an optimized and reliable backbone transmission structure, so the core layer switch application has higher reliability and throughput. The aggregation layer switch is the convergence point of multiple ac... Read More
