Types of ethernet magnetics
The ethernet magnetics can be divided into two parts, which are the power line filter and the signal line filter.
The power line filter is used to protect the devices from disturbances generated by using electricity. The power lines are also called mains or AC (alternating current).
The signal line filter is commonly used to filter out any noise that may affect signals, or in other words, it’s a kind of cable that helps to remove any interference and unwanted signals that may affect communication equipment such as routers and switches.
What are discrete magnets for ethernet?
Discrete magnets for ethernet are used to protect the devices from disturbances generated by using electricity. These magnets are also called mains or AC (alternating current). The discrete magnetics are used with the help of a ferrite core, which is a kind of material that can be used to control the flow of electrons in a conductor.
The discrete magnets for ethernet are also known as power line filters and it’s one of the most common filters that can be found in all kinds of networking equipment. Discrete magnetics are used to protect networking equipment from electromagnetic interference and radio frequency interference.
What is the purpose of discrete magnetics?
Discrete magnets for ethernet have two functions, which are:
Protect networking equipment from electromagnetic interference
Protect networking equipment from radio frequency interference.
What is EMI?
Electromagnetic interference (EMI) occurs when the electric and magnetic fields are disturbed by different sources of electromagnetic radiation. These disturbances are created by the electric conductors and it’s also known as crosstalk. EMI can cause damage to cables, network cards, network interface cards, hubs, and other networking equipment.
It’s one of the most common problems that can occur in a network. Molding or shielding can be done for cables to avoid EMI. Discrete magnetics for ethernet help to reduce EMI caused by power lines.
To protect networking equipment from radio frequency interference (RFI).
What is integrated magnetics?
Integrated magnetics are integrated circuits that are molded into network cards or ethernet cables. It’s molded in the PCB to protect networking equipment from electromagnetic interference and radio frequency interference. The integrated magnetics for ethernet can be used for both twisted pair and fiber optic cables.
EMI is a problem that can be solved by using integrated magnetics for ethernet. Integrated magnetics for ethernet helps to protect networking equipment from electromagnetic interference and radio frequency interference. It can also help to reduce crosstalk and electrical noise between twisted pair cables, fiber optic cables, and power lines.
How to compare ethernet magnetic modules?
This is a common question for those who want to buy ethernet magnetic modules. And the answer is not difficult. As we all know, Ethernet magnetic modules can be divided into two parts: The core and the shell. The core part is the main body of the module and contains all the components of the module. The shell part is a plastic covering that protects the core part of the module, it also has some functional significance, such as enhancing the appearance and protecting components. Thus, when you want to buy Ethernet magnetic modules, you should pay attention to what kind of shell you need for it.
Ethernet Magnetic Module Shell Parts
The shell parts are mainly composed of two parts: The shell and the ring magnet. The shell part provides protection for the core part of the module during transportation and installation. Its surface is smooth and has a beautiful appearance; it can also enhance stability when installed on a building wall.
The ring magnet is located on the bottom of an Ethernet magnetic module’s shell; it connects with other modules through electromagnetic induction so that they can work together as one entity (a single Ethernet network
Ethernet Magnetic Module Core Parts
The core parts are mainly composed of two parts: The circuit board and electronic components. There are many kinds of electronic components on an Ethernet magnetic module’s circuit board, such as transistors, resistors, capacitors, diodes, and so on; they all play an important role in providing power supply for the module, as well as ensuring the normal operation of the magnetic network.
The circuit board of an Ethernet magnetic module is usually made of an FR4 board, which is a kind of flame-resistant material. As for its size, it can be designed according to customers’ requirements. In addition, the circuit boards have high thermal conductivity and good insulation properties, which make them easy to be used in harsh environments and under high temperatures.
Factors to consider when selecting ethernet magnetics
The factors to consider when selecting ethernet magnetics include
The type of network that is being used: If it’s a twisted pair network then a magnetic transformer should be used. If it’s a fiber-optic network then a ferrite bead should be used.
The frequency and the level of EMI should also be considered when selecting integrated magnetics for ethernet.
The size and the shape of the ethernet cable that is being used should also be considered.
If it’s a fiber-optic network then the fiber cable should be taken into consideration. The type of fiber cable that is being used determines the type of magnetic component that should be used: A ferrite bead or a magnetic transformer.
The level of EMI that is present on the network should also be considered when selecting integrated magnetics for ethernet. If there is a high level of EMI then higher quality magnets should be used.
Once you consider all the above factors, you will be in a perfect position to buy the best ethernet magnetics.
