Optical bus cross-coupler for data traffic within multiple modules arranged in rows and columns, feeds data traffic from upstream or downstream bus users through optical part of bus coupler

摘要

The data traffic from upstream or downstream bus users are fed through the optical part of the bus coupler. Thereby, only a small insertion loss is suffered by the optical bus signals, dependent on the material used, and the bus coupler does not need to supply any additional energy for the transport of these data.
