  • 1. 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.

  • 2. 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.

  • 3. 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).

  • 4. How to distinguish different models of Modular Connectors - Jacks With Magnetics?

    Models are usually distinguished by the following features:

    Port configuration: such as 1x1, 1xN or 2xN.

    Rate: such as Cat5e, Cat6 or Cat6A.

    Mounting direction: right angle or vertical mounting.

    Additional features: such as LED indicator or shielding design.
