摘要： A passive optical network comprises a first node configured to transmit a downlink data signal over a communication channel of an optical link, the communication channel having a first wavelength, and a second node configured to transmit an uplink data signal over the optical link using the communication channel having the first wavelength. The first node and/or the second node is adapted to perform at least one monitoring measurement on the communication channel having the first wavelength, and provide monitoring information, comprising the at least one monitoring measurement, in a monitoring channel. Common public radio interface (CPRI) traffic can therefore be transported over an optical transport network (OTN), by using a frequency reuse technique to provide a symmetrical bi-directional communication link between a first node and a second node, and using a frame structure of the optical transport network to provide a monitoring channel.

摘要： An optical sampler with high temporal resolution comprises a TOAD device with a loop optical path at the inlet of which is input an optical signal to be sampled and along which path is arranged a point of input of an optical control signal produced by a source and appropriately delayed by a delay line to change on command the temporal position of the TOAD transmittance window compared to the signal to be sampled. In the loop there is also a nonlinear device. The sampler includes a controller to command the delay line to move step by step the transmittance window and make it run on the signal to be sampled. The mean power transmitted at the TOAD output is measured for each window position and a derivative on the mean powers found for each window position is performed, thus finding samples representing the optical signal.

摘要： A radio base station has a baseband controller coupled to a radio head by an optical wavelength division multiplexed link to pass downlink signals on a first wavelength, and uplink signals on another wavelength. A compensating delay is applied to one of the signals to compensate for a difference in transmission times between the downlink and the uplink signals. The compensating delay can be controlled according to the difference in wavelengths. By compensating for such differences in transmission times, synchronisation problems can be avoided or ameliorated, or transmission distances can be increased. This can result in more flexibility in choice of wavelengths, fiber types and fiber lengths, and greater resilience. This can enable simpler installation or configuration, or reconfiguration without needing to take care to restrict the selection of wavelengths on the WDM link or restrict the length of the link for example.
