摘要：An optical ring network architecture including a number (N) of multi-add/dropfilters, such as filters formed using symmetrical pairs of frequency routers. Each multi-add/drop filter is coupled to two other multi-add/drop filters using N−2 transmissionmedia, such as optical fibers, to form a ring. The network also includes a number (N) of

terminal stations associated with the multi-add/drop filters. A terminal station (p) iscoupled with, and receives information from, its associated multi-add/drop filter (p)through a single optical fiber. In addition, the terminal station p is coupled with, andtransmits information in a first direction around the ring to, a multi-add/drop filter p+1through a single optical fiber. Communications from terminal station p to each otherterminal station in the first direction are assigned one of N−1 wavelengths such that notwo wavelengths on a given optical fiber are associated with communications betweenterminal stations in the same direction. Moreover, all wavelengths on a given optical fibermay be associated with a communication between terminal stations in either the first orsecond direction. As a result, each terminal station can communicate with each otherterminal station simultaneously using wavelength division multiplexing and N−1

wavelengths. The network may also be bi-directional such that each terminal station p iscoupled with, and transmits information in a second direction opposite the first directionto, a multi-add/drop filter p−1 through a single optical fiber.
