IEEE 802.3 1000Base-RH

1000Base-RH is a specification for Gigabit Ethernet developed by the IEEE working group 802.3bv, GEPOF. 1000Base-RH was developed for automotive Ethernet and uses polymer fibers as the transmission medium

. Polymer fibers have the advantages that they are resistant to electromagnetic emission, galvanically isolate connected components and can be laid quickly and cost-effectively. The properties in terms of electromagnetic interference and electromagnetic interference sensitivity also make the polymer connections suitable for communication between the 12 V vehicle electrical system and the 48 V vehicle electrical system. 1000Base-RH uses 64B66B coding and can span a distance of approximately 700 m. It has parity checking and a cyclic block check, CRC16. Ethernet-compatible connections

withdata rates of 100 Mbit/s and 1 Gbit/s

arepossible over 1000Base-RH.

1000Base-RH has some similarities with 1000Base-T1. The main differences lie in the implementation ofOperation, Administration, and Maintenance (OAM). With 1000Base-RH, the OAM messages are transmitted as user data in the Physical HeaderData (PHD).
