Abstract:
An optical ring network architecture including a number (N) of multi-add/drop filters, such as filters formed using pairs of frequency routers. Each multi-add/drop filter is coupled to two other multi-add/drop filters using N-2 transmission media, such as optical fibers, to form a ring. The network includes a number (N) of terminal stations associated with the multi-add/drop filters. A terminal station (p) is coupled with, and receives information from, its associated multi-add/drop filter (p) through a single optical fiber. The terminal station p is coupled with, and transmits information in a first direction around the ring to, a multi-add/drop filter p+1 through a single optical fiber. Communications from terminal station p to each other terminal station in the first direction are assigned one of N-1 wavelengths where no two wavelengths on a given optical fiber are associated with communications between terminal stations in the same direction.
