7. A network, comprising:
-
a plurality of optical pathways coupled to a plurality of customer locations; a distribution and switching center generating a plurality of optical signals for transmission to the plurality of customer locations over the plurality of optical pathways; at each of the customer locations, an optical connector terminating the respective optical pathway; and a plurality of optical blockers physically separate from the optical connectors, each located along one of the optical pathways at a location closer to the optical connector of the respective customer location than to the distribution and switching center. - View Dependent Claims (8, 9, 10, 11, 12)
