TC7 – Gigabit Ethernet over Optical Fiber

TC7 was created to work on optical multi-gigabit ethernet for automotive applications. The group’s objective is to create supplemental documentations for in-vehicle implementations such as connector interfaces, footprints, and test suites that are outside the scope of IEEE802.3cz.

TC7 handles all technical areas and requirements related to optical communications:

  • Communication channel
  • Connectors, optical cables, optical cable assemblies and wiring harnesses
  • Measurement setup and procedures
  • Opt-Electrical requirements
  • EMC requirements

Seven subgroups were established corresponding to the above scopes and to promote their activities.
