FAQ

What is 100BASE-T1?

100BASE-T1 means Automotive Ethernet with a data transmission rate of 100 Mbps via a pair of cores.

What is Automotive Ethernet?

Automotive Ethernet means Ethernet for vehicles with the goal of standardizing the data transmission in the on-board power system. Automotive Ethernet is a core technology for the realization of the future on-board power system.

Is it possible to transmit Ethernet via a HSD cable?

The transmission of Automotive Ethernet is possible under certain conditions. The protocol 100BASE-TX can be transmitted via a HSD cable, for example.

When can I use HSD and when should I use Coax?

This has to be considered in individual cases by means of the application and the planned protocol.

What is the difference between HSD and FAKRA?

HSD includes 4 pins and a double shielding (in standard cases), FAKRA includes 1 pin and a double shielding (in standard cases). The applicability has to be checked individually depending on the application and the protocol.

Up to which frequency can HSD be used?

This depends on the cable used. Usually, cables up to 1 GHz or 3 GHz are quoted.

When can I use a STQ (four-wire) cable and when should I use STP (double-wire)?

A double-wire cable can be used if two control units need to be connected with one data pair.

A four-wire cable can be used if two control units need to be connected with two data pairs under one joint shield.
