1. Different working levels: Layer 2 switches work at the data link layer, and Layer 3 switches work at the network layer. Layer 3 switches not only achieve high-speed forwarding of data packets, but also achieve optimal network performance according to differ...

Our country's telephone optical transceivers have developed rapidly with the development of the monitoring industry. From analog to digital, and then from digital to high-definition, they are constantly advancing. After years of technical accumulation, they ha...

With the development of the communication industry and the informatization of the national economy, the managed ring network switch market has grown steadily. It is cost-effective, highly flexible, relatively simple and easy to implement. Ethernet technology h...

The function of fiber optic transceivers is to convert between optical signals and electrical signals. The optical signal is input from the optical port, and the electrical signal is output from the electrical port, and vice versa. The process is roughly as fo...

What is IEEE 802.3? IEEE 802.3 is a working group that wrote the Institute of Electrical and Electronics Engineers (IEEE) standard set , which defines medium access control (MAC) at both the physical and data link layers of wired Ethernet.  This is usually a ...

Optical fiber transceiver is a very cost-effective and flexible device. The common use is to convert electrical signals in twisted pairs into optical signals. It is generally used in Ethernet copper cables that cannot be covered and must use optical fibers to ...

What is Ring network redundancy? A ring network uses a continuous ring to connect each device together. It ensures that the signal sent by one device can be seen by all other devices on the ring. The ring network redundancy refers to whether the switch support...

What is Network Topology Network topology refers to the physical layout features such as the physical connection of various transmission media, network cables, and abstractly discusses the interaction of various endpoints in a network system by borrowing the ...

What is STP? STP (Spanning Tree Protocol ) is a communication protocol that works on the second layer (data link layer) in the OSI network model. Its basic application is to prevent loops caused by redundant links in switches. It is used to ensure that there...

What is a broadcast storm? A broadcast storm simply means that when the broadcast data floods the network and cannot be processed, it occupies a large amount of network bandwidth, resulting in the inability of normal services to run, or even complete paralysis...
