Abstract:
A transparent fiber-optic communication network having several central systems that are connected to one another via optical fibers, each central system connected to at least one decentralized optical system by two optical feed fibers, and including:monitoring equipment; a first optical fiber connected to the at least one decentralized optical system by a first optical feed fiber in an optically transparent fashion via the monitoring equipment; and a second optical fiber connected to the at least one decentralized optical system by a second optical feed fiber in an optically transparent manner via the monitoring equipment, wherein the first and second optical feed fibers are operated without using a wavelength division multiplexing technique; and wherein the central system includes a regeneration unit and the first optical fiber is connected to the decentralized optical system by the first optical feed fiber in an optically transparent fashion via the monitoring equipment and via the regeneration unit, and the second optical fiber is connected by a second optical feed fiber to the decentralized optical system through the monitoring equipment and through the regeneration unit.
