1. What are Modular Connectors - Jacks With Magnetics?
Modular Connectors - Jacks With Magnetics are modular connectors with integrated magnetic components, mainly used in high-speed data transmission scenarios such as Ethernet. Magnetic components (such as transformers and filters) are used for signal isolation, impedance matching and anti-electromagnetic interference (EMI), ensuring the stability and reliability of data transmission.
-
2. Why do we need to integrate magnetic components?
The main purpose of integrated magnetic components is to meet the requirements of Ethernet standards such as 10/100/1000 Base-T and PoE. Magnetic components provide electrical isolation, signal balance and transient protection, while reducing electromagnetic interference (EMI), ensuring the stability of high-speed data transmission.
-
3. How to choose the right Modular Connectors - Jacks With Magnetics?
Factors to consider when choosing:
Number of ports: single-port, multi-port, or stacked configurations.
Speed support: such as 1Gb/s, 10Gb/s, or higher.
Mounting method: panel mount, onboard mount, or through-hole mount.
Shielding performance: whether EMI/RFI shielding is required. -
4. What is PoE support? Why is it important?
PoE (Power over Ethernet) allows data and power to be transmitted simultaneously over Ethernet cables, reducing wiring complexity. Modular Connectors - Jacks With Magnetics support PoE and are suitable for devices that require remote power supply (such as IP cameras and VoIP phones).
