optoLAN-Gb 88Q2112

The optoLAN-GB 88Q2112 system

This optoLAN-Gb 88Q2112 system is a digital, bidirectional, optical transmission device for automotive Ethernet 1000Base-T1/100Base-T1 signals.

There are two setups available, T1 to T1 (standard) or T1 to T (mit integriertem Medienkonverter => optoLAN-Gb), siehe separates Setup-Dokument.

The standard connector is Rosenberger HSD (Z-coded). With the optical transmission, the shielded case and the high quality connector, the system is well equipped for EMI and EME tests and has proven its functionality in many automotive EMC labs already.
