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. What Ethernet standards do Modular Connectors - Jacks With Magnetics support?
These connectors typically support 10/100/1000 Base-T, 2.5Gb/s, 5Gb/s, and 10Gb/s Ethernet standards, and are compatible with PoE (Power over Ethernet) Type 1 to Type 4.
-
4. Do these connectors support high-reliability (Hi-Rel) applications?
Yes, many Modular Connectors - Jacks With Magnetics are designed for high-reliability scenarios, with EMI/RFI shielding, protective shell and high durability, suitable for military, aerospace and industrial automation.
