An optical network comprising: (a) a plurality of different optical fiber
receptacles for facilitating an optical connection to different
information networks requiring different access authorization, each
different optical fiber receptacle optically coupled to one and only one
different information network, each optical fiber receptacle having an
inner surface with a first geometry, the first geometry comprising at
least a slot, a certain number of optical fiber receptacles having
different first geometries in which the slots are in different positions;
and (b) a plurality of different optical fiber plugs for optically
coupling with the different optical fiber receptacles, each optical fiber
plug having a second geometry, the second geometry comprising at least a
key in a certain position, the certain number of optical fiber plugs
having different second geometries in which the keys are in different
positions, each different first geometry corresponding to one and only
one second geometry such that the optical fiber plugs and receptacles of
corresponding first and second geometries are mating pairs.
