Back-plane optical bus coupler for data traffic within back-plane, has data traffic for upstream or downstream bus users fed through optical part of bus coupler

摘要

The data traffic from upstream or downstream bus users is fed through the optical part of the bus coupler. Thereby, the insertion loss suffered by the optical bus signals is low, depending on the material used. No additional energy is needed to be supplied by the bus coupler for the transport of these data.
