Access Layer Switch Usually, the part of the network that is directly connected to users or accesses the network is called the access layer, and the part between the access layer and the core layer is called the distribution layer or the convergence layer. Acc...

Switching Capacity The switching capacity of the switch, also known as the backplane bandwidth or switching bandwidth, is the maximum amount of data that can be handled between the switch interface processor or interface card and the data bus. The exchange cap...

What is the difference between Ca5e, Cat6, and Cat7? Category Five (CAT5): The transmission frequency is 100MHz, used for voice transmission and data transmission with a maximum transmission rate of 100Mbps, mainly used in 100BASE-T and 10BASE-T networks. This...

The 1*9 packaged Optical Module product was first produced in 1999. It is a fixed optical module product. It is usually directly cured (soldered) on the circuit board of the communication equipment and used as a fixed optical module. Sometimes it is also calle...

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 ...
