Abstract
An optical network with at least two nodes is provided comprising optical fiber, at least two active fiber-bays per node optically coupled to the fiber, and at least one redundant fiber-bay per node optically coupled to the fiber. When an active fiber-bay fails, the network changes from the failed fiber-bay to a redundant fiber-bay. Further, the number of redundant fiber-bays is less than the number of active fiber-bays.
Claims25
An optical network with at least two nodes comprising:
- an optical fiber;
- at least two active fiber-bays per node optically coupled to said fiber;
- and
- at least one redundant fiber-bay per node optically coupled to said fiber,
- wherein when an active fiber-bay of said at least two active fiber-bays fails, said network changes from said failed fiber-bay to a redundant fiber-bay of said at least one redundant fiber-bay, and
- wherein the number of said at least one redundant fiber-bays is less than the number of said at least two active fiber-bays.
