摘要： Systems, computer program products, and methods are described herein for network discovery, port identification, and/or identifying fiber link failures in an optical network, in accordance with an embodiment of the invention. The present invention may be configured to sequentially connect each port of an optical switch to a network port of a server and generate, based on information associated with network devices connected to the ports, a network map. The network map may identify which network devices are connected to which ports of the optical switch and may permit dynamic port mapping for network installation, upgrades, repairs, and/or the like. The present invention may also be configured to determine a fiber link in which a failure occurred and reconfigure the optical switch to allow communication between an optical time-domain reflectometer and the fiber link to test the fiber link.

摘要： The invention relates to a device and a method performed by the device of monitoring an optical fibre link. The method provided for monitoring an optical fibre link comprises generating a monitoring signal used for monitoring the optical fibre link, combining the generated monitoring signal with a data signal to be transmitted over the optical fibre link, detecting backscattering of the monitoring signal from the optical fibre link, comparing the detected backscattered monitoring signal with an estimated monitoring signal backscattered along the optical fibre link, and determining, based on the comparison, at least one location along the optical fibre link where the monitoring signal is backscattered, and signal loss caused by the backscattering.

摘要： Systems and methods for in-service optical fault isolation on a link between a first node and a second node include transmitting counters between each of the first node and the second node; determining associated values for the counters responsive to an event associated with the link; and determining a location of the event based on the associated values for the counters. The determining includes converting time differences between the counters into distance, based on propagation speed of a signal over optical fiber forming the link. The location is determined in-service based on a single occurrence of the event without external equipment.

摘要： In one embodiment, a system for analyzing optical networks includes a network analyzer optically coupled to a fiber optic network. The network analyzer may transmit a test signal to the fiber optic network, receive a reflected signal in response to transmitting the test signal, wherein the reflected signal is generated in response to the test signal interacting with a defect of the fiber optic network. The analyzer may then analyze a power of the reflected signal, wherein the power of the reflected signal corresponds to the defect in the fiber optic network, calculate a transmit time of the reflected signal, wherein the transmit time corresponds a location of the defect in the fiber optic network, identify a component of the fiber optic network corresponding to the defect and the location of the defect in the fiber optic network, and generate a maintenance report based on the analyzed reflected signal.

The method includes transmitting a signal into a fiber in a first direction; receiving, at the polarimetric measurement device, the signal from one of the fiber and another fiber collocated in a bundle with the fiber in a second direction; and processing data from the polarimetric measurement device to determine a location of the one or more SOP transients. The processing can include detecting a presence of the one or more SOP transients based on a first signature and its echo seen in the data; and converting a time between the echoes into a distance.

摘要： Systems, methods, and apparatuses for protecting daisy chain networks from node malfunction or power outage are disclosed. One or more communication nodes in a daisy chain network can be bypass-capable communication nodes. Bypass-capable communication nodes can include a sensing and switching subsystem, embedded in the node or external to the node in a fiber optic cable running along the daisy chain network. In embodiments, the sensing and switching subsystem can responsively switch the bypass-capable communication node from communication node primary circuitry to primary circuitry responsive to node malfunction or node power outage. The sensing and switching subsystem also can switch back from bypass circuitry to primary circuitry responsive to restoration of node function or node power. In embodiments, switching occurs responsive to excitation or de-excitation of the node itself.
