Parallel light paths
If two light paths are installed next to each other without any optical separation,
the optical data couplers must be installed opposite each other in pairs. This is to
avoid cross-talk. A minimum distance "a" between the beam axes is not required,
provided that the adjacent pairs have the identical overall distance "d."
