    摘要: A bi-directional telemetry service channel is provided on a single optical fiber using two wavelengths that are accessible through multiplexing devices. A bi-directional telemetry service channel is also provided on a single optical fiber using only a single wavelength. A fully protected bi-directional telemetry service channel can be provided using only two optical fibers. When a single wavelength is used, a time window is provided for transmission of telemetry service signals in one direction on the optical fiber at the single wavelength, and a second time-window is provided for transmission of telemetry service signals in the opposite direction on the same optical fiber using the same wavelength.

    摘要: The system and method of the present invention provide restoration of coincident line and facility failures. The system of the present invention includes light termination equipment (LTE) that is capable of detecting failures, determining the type of component that failed, determining which restoration facility to use based on the type of component that failed, and providing restoration. The system of the present invention also includes spare capacity for restoration, including protect channels and an optical restoration network. In addition, the system of the present invention includes an optical cross connect switch (OCCS) that is capable of switching electrical signals to the optical restoration network. The method of the present invention is involves detecting a failure, determining the type of component that failed, and sending an alarm to a centralized management center.

    摘要: In one implementation, a system detects that a fiber within a fiber optic cable has failed and automatically causes a location of a faulty portion of the fiber to be identified in response to the detecting. In another implementation, a central office includes a first optical patch panel operably coupled to an optical fiber and a second optical patch panel configured to couple the first optical patch panel to a test device. The optical fiber is automatically coupled to the test device in response to one or more signals from a remote management device.

    摘要: The present invention generally relates to a network and method capable confirming proper communications of high data rate optical signals between communications network devices. In particular, the present invention teaches a method of creating a "Line Trace" byte to be placed in the Line Overhead portion of the Transport Overhead of a SONET STS-1 frame optical data signal. Current Line Overhead does not incorporate any Trace functionality. With the increasing use of optical cross-connect switches within a communications network, it is essential for a network service provider to have the flexibility to move Line Terminating Equipment around via the optical switches. Thus, the present invention offers a straightforward, efficient way to achieve this necessary flexibility.
