Interconnected broadcast and select optical networks with shared wavelengths
First Claim
1. A method of transmitting optical signal traffic, comprising:
- providing an all optical network with at least two rings that are geographically dispersed, each ring including at least one transmitter and at least one receiver;
separating the available wavelengths into distinct ring bands;
sharing the optical signal traffic throughout the entire optical network; and
providing each ring with its own distinct ring band of the optical signal traffic, wherein all of the optical signal traffic is transmittable throughout the optical network and each receiver is configured to receive only wavelengths in a ring band designated for its associated ring.

Abstract
These and other objects of the present invention are achieved in a method of transmitting optical signal traffic. An all optical network is provided with at least two rings that are geographically dispersed. Each ring includes at least one transmitter and at least one receiver. The available wavelengths are separated into distinct ring bands. The optical signal traffic is shared throughout the entire optical network. Each ring is provided with its own distinct ring band of the optical signal traffic. All of the optical signal traffic is transmittable throughout the optical network. Each receiver is configured to receive only wavelengths in a ring band designated for its associated ring.

41. A method of transmitting optical signal traffic, comprising:
-
providing an all optical network with hierarchical rings, each of a hierarchical ring including a plurality of nodes and each node including at least one transmitter and one receiver;
separating the optical signal traffic into ring bands;
transmitting the optical signal traffic through all of the hierarchical rings; and
providing each hierarchical ring with its own distinct ring band, wherein all of the available wavelengths are transmittable throughout each hierarchical ring, and the receivers of a hierarchical ring are configured to receive only wavelengths in a ring band that is designated for that hierarchical ring.

42. An all optical network for optical signal traffic, comprising:
-
at least a first and a second ring, each ring having at least one transmitter and one receiver and its own distinct ring band of the optical signal traffic, wherein all of the optical signal traffic is transmittable throughout the entire all optical network and each receiver is configured to receive only wavelengths in a ring band designated for its associated ring; and
a central hub that couples the at least first and second rings, the central hub separating the optical signal traffic into ring bands. - View Dependent Claims (43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60)

61. An all optical network, comprising:
-
a first ring with at least a first and a second protection fibers that carry all of the optical signal traffic, wherein the optical signal traffic travels in a clockwise direction in the first protection fiber and in a counter-clockwise direction in the second protection fiber, and at least one 1×
1 or a 1×
2 switch coupled to each first and second protection fiber, wherein the 1×
1 or 1×
2 switch is maintained in an open position when there is no break point in the ring and closed upon an occurrence of a break point in the ring. - View Dependent Claims (62, 63)
