1. 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.
-
2. 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).
-
3. 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.
-
4. How to solve the compatibility issues of Modular Connectors - Jacks With Magnetics?
Ensuring that the connector is compatible with the cable, device and network standards is key. Choose products that comply with RoHS and IEC 60603-7 standards, and check whether their speed, PoE support and shielding performance meet the requirements.
