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. Are Modular Connectors - Jacks With Magnetics complicated to install and maintain?
The installation is relatively simple and can usually be completed with standard tools (such as crimping tools). In terms of maintenance, due to its modular design, it is very convenient to replace or upgrade the connector, which is suitable for field installation and repair (MRO) scenarios.
-
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.
