optoLAN 100Base-T1 BCM89811

The optoLAN-BCM89811 system

The optoLAN-BCM89811 system can be used for the optical transmission of automotive ethernet signals with Broadcom© BCM89811© and other 100BaseT1 chipsets.

There are two setups available, T1 to T1 (standard) or T1 to Tx (with integrated media converter => optoLAN-BCM89811 -MC), see separate setup document.

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.
