Abstract |
AB |
[EN] The invention pertains to methods, apparatus, and systems optical of networking using tunable receivers, optical blocking elements selectively placed in the network, and optical routing elements comprised of passive elements, such as optical couplers and splitters. The routing elements have a plurality of ports and comprise passive elements such as couplers and splitters configured so that input light received at any port of the element is output from each of the other ports of the element, but not at port at which it was input. |
