Description
30F-21 is 10/100/1000 BASE-T magnetic module.
A 10/100/1000 BASE-T magnetic module, also known as a Gigabit Ethernet magnetic module, is a component used in networking equipment, such as switches, routers, and network interface cards (NICs), to provide physical layer connectivity for Ethernet networks. It is responsible for transmitting and receiving data signals over twisted pair cables.
Here are some key features and functions of a 10/100/1000 BASE-T magnetic module:
Speed and Compatibility: The module supports data transmission speeds of 10 Mbps (Ethernet), 100 Mbps (Fast Ethernet), and 1000 Mbps (Gigabit Ethernet). It is designed to be backward compatible with lower-speed Ethernet standards, allowing it to connect to devices operating at different speeds.
Magnetic Transformers: The module includes magnetic transformers, which are responsible for coupling data signals onto and off the twisted pair cables. These transformers help isolate the Ethernet signals, provide impedance matching, and help reduce noise and interference.
Integrated Magnetics: The magnetic module integrates the required transformers, capacitors, and other passive components into a single package. This integration helps reduce the overall footprint and simplifies the design and assembly of Ethernet interfaces.
RJ-45 Connector: The module typically includes an RJ-45 connector, which is the standard interface for Ethernet connectivity. The RJ-45 connector allows the module to be easily connected to twisted pair Ethernet cables.
