The diagram above illustrates a typical point-to-point media conversion scenario, supporting a range of data rates to bridge between standard Ethernet and Automotive Ethernet
On the Ethernet BASE-TX side, 100 Mbps,1000 Mbps, and now also 10 Gbps, most often connected with RJ-45, but if SFP-port any SFP+ transceiver or DAC can be connected. USB is also available on the market, with some concerns
On the Automotive Ethernet BASE-T1 side, 100 Mbps and 1000 Mbps speeds are the most common, but now the new 2,5, 5, and 10 Gbps are rising. The most common connector is the H-MTD connector but others like MATEnet, MQS and D-sub are also available.
Speeds: 100 Mbps, 1000 Mbps (1 Gbps), and 10 Gbps are supported.
Connectors: Typically RJ-45, but SFP/SFP+ ports allow for the use of various SFP/SFP+ transceivers or Direct Attach Copper (DAC) cables. USB connectivity is also available, though it may present certain limitations in some applications. M12 connectors are also used for IP classification.
Speeds: While 100 Mbps and 1000 Mbps are most common, emerging speeds of 2.5 Gbps, 5 Gbps, and 10 Gbps are increasingly prevalent.
Connectors: H-MTD is the most common connector type, but MATEnet, MQS, M12 and D-sub connectors are also used.
Below is a comparison of various media converter devices that we recommend based on our experience
Choosing the optimal media conversion solution for your Automotive Ethernet needs can be challenging. We understand that factors like reliability, flexibility, price, and performance are crucial. What are your biggest priorities? Let us know your specific challenges so we can help you find the perfect fit.
For maximum reliability, single media converters offer a dedicated point-to-point conversion. However, if you need to connect multiple devices, a switching solution might be a more cost-effective option. While switches can be advantageous in certain scenarios, they also introduce some trade-offs that should be carefully considered for example latency, management overhead, packet drop, etc.
When selecting a media converter, consider these essential features:
Speed Conversion:Support for your required Automotive Ethernet BASE-T1 and Standard Ethernet BASE-TX speeds
Voltage Range: Compatibility with your system's voltage requirements
Connector Types:Availability of the necessary connectors (e.g., H-MTD, MATEnet, RJ-45, SFP/SFP+, M12)
Link Status Indication: Clear output of link status via appropriate connectors for easy troubleshooting
Debugging and TAP(Test Access Point) Capabilities:Features that facilitate debugging, diagnostics and TAP to decouple data
Signal Quality Indicator (SQI) Support:For monitoring signal integrity
Robust Casing and Protection: Suitable environmental protection, such as IP-67 classifikation
Additional Interfaces:Optional features like USB to CAN/CAN FD interfaces can expand functionality
Advanced Features:Support for TC10 (sleep mode/wake-up) or MACsec (security) for enhanced performance and security.
