1. 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. -
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 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.
