    摘要： A device for measuring optical latency in a test path includes an optical source to generate an optical signal. An optical modulator modulates the optical signal based on a modulation signal. An output port outputs the modulated optical signal to the test path. An input port receives a return optical signal following propagation through the test path. Latency calculating logic calculates the optical latency for the test path based on the modulation signal and the return optical signal.

    摘要： A optical switch and switching system is provided for effecting a switchover from a first optical fiber to a second optical fiber includes a first, large scale switching component and a second, small scale switching component. The first, large scale switching component is configured to establish a cross connect between the second optical fiber and the second, small scale switching component. The second, small scale switching component may then be configured to select the cross connect following establishment of the cross connect, thereby ensuring rapid switchover from the first fiber to the second fiber, regardless of the speed of the first large scale switching component.

    摘要： First and second switching device are connected by a number of signal paths. The first switching device receives an instruction to switch from a first one of the signal paths to a second one of the signal paths. The first switching device performs, in response to the received instruction, a first switching operation to connect the first path, at an input of the first switching device, to the second path, at an output of the first switching device. The second switching device receives the instruction to switch from the first path to the second path and detects a loss of signal on the first path as a result of the first switching operation performed by the first switching device. The second device performs, in response to detecting the loss of signal on the first path, a second switching operation to connect the first path, at an output of the second switching device, to the second path, at an input of the second switching device.

    摘要： A system generates optical pulses, that include two frequencies within one optical channel, at a first end of an optical link, and receives the optical pulses at a second end of the optical link. The system also sets a frequency difference for the two frequencies of the optical pulses, calculates a relative group delay difference for the two frequencies of the optical pulses, and calculates a residual chromatic dispersion of the channel based on the frequency difference and the calculated relative group delay difference.
