POE switch technology and advantages introduction
A PoE switch is a switch that supports power supply to the network cable. Compared with ordinary switches, the power receiving terminal (such as AP, digital camera, etc.) does not need to be wired for power supply, which is more reliable for the entire network.Today, JHA Technology will introduce...Read more -
How to choose optical fiber and copper wire?
Understanding the performance of optical fiber and copper wire can make a better choice. So what characteristics do optical fiber and copper wire have? 1. Copper wire characteristics In addition to the above-mentioned good anti-interference, confidentiality, and convenient installation/maintenanc...Read more -
What is the difference between optical fiber and copper wire?
The choice of data center transmission media is always a controversial topic, especially in dedicated facilities (such as data centers). Technical and business issues need to be considered. Some people think that copper wires should be chosen, while others think that they should be chosen. optica...Read more -
Can the single-mode and multi-mode of industrial switches replace each other?
When purchasing an industrial switch, customers will be asked whether they want single-mode single fiber, single-mode dual-fiber, multi-mode dual-fiber, etc., and where they are used. These will only be understood when they have a clear understanding of the purchase of industrial switches. What t...Read more -
How to use PoE Injector?
How does the PoE injector work? When switches or other devices without power supply function are connected to powered devices (such as IP cameras, wireless APs, etc.), the PoE power supply can provide power and data transmission support for these powered devices at the same time, with a transmiss...Read more -
What is a PoE injector?
PoE (Power over Ethernet) refers to a power over Ethernet technology that simultaneously transmits power and data through a twisted pair cable. The application of this technology can effectively improve the stability and flexibility of the network, so it is widely favored by people. At present, t...Read more -
Divide the Ethernet switch port type according to the transmission rate
Transmission rate is a crucial factor in determining the type of Ethernet switch port. At present, the transmission rate of Ethernet switches is 1G/10G/25G/40G/100G or even higher. The following are the mainstream port types of these Ethernet switches with different transmission rates. RJ45 por ...Read more -
How to solve the network delay caused by the Ethernet switch.
How to measure the network delay in an Ethernet switch? As can be seen from the previous chapter, switch delay is one of the key factors leading to network delay. So how do we measure switch latency? Switch delay is measured from port to port on the Ethernet switch, and can be reported in multipl...Read more -
What is the network delay in an Ethernet switch?
Network latency refers to the network waiting time, which refers to the round-trip time for a data packet to be sent from the user’s computer to the website server, and then immediately from the website server to the user’s computer. Network delay is one of the factors that affect net...Read more -
Compare PoE+ and PoE++ switches
Power over Ethernet (PoE) is a power supply technology based on a local area network (LAN), which can transmit power and data to the device through a network cable in the Ethernet. The application of this technology can greatly reduce operating costs and save operating time. At present, there are...Read more -
Switch redundant power supply design
Currently, most switches on the market, especially old switches, only use a single power supply. If the power supply fails (such as power failure), the switch cannot operate normally, or even paralyze the network.Redundant power supplies are an ideal solution to this problem. Switches designed wi...Read more -
Why are SFP optical modules popular?
Why are SFP optical modules popular? The volume of the SFP optical module is reduced by half compared with the volume of the GBIC optical module. The number of SFP ports on the same panel will be twice that of the GBIC optical module. The same SFP optical module has a plug-and-play mini optical f...Read more
