摘要： A communications system connects one or more BTS hotels with several remote access nodes on a transmission ring. Each operator has one or more separate optical wavelengths. Signal flow around the ring can either be uni-directional or bi-directional. Each optical wavelength (or wavelength pair) contains the wireless signal traffic for all remote nodes in the ring for the operator using that particular wavelength in digital form. At each node, the incoming signals are electrically demultiplexed and appropriate signals for that node are extracted for conversion to RF. These signals are copied rather than cut so that they are also available at following remote antenna nodes, thereby enabling simulcast operation.

摘要： A switch for the switching of communications system signals, with m input ports and n output ports, comprising two or more parallel switch matrices (8a, 8b), each of size m x n, combined so that each switch matrix (8a, 8b) contributes to the available output power at each output port. The failure of one of the switch matrices (8a, 8b), or one of the transmission paths therein, will therefore result only in a small reduction in the output power at the relevant output port, rather than complete power loss as would be the case for a conventional switch This fault condition can be detected using a power imbalance detection circuit in the switch matrix combiner. Additionally, the fault condition, having been detected by the power imbalance detection circuit, may be temporarily compensated by an automatic level control system.
摘要翻译：用于切换具有m个输入端口和n个输出端口的通信系统信号的开关包括两个或更多个大小为mxn的并行开关矩阵（8a，8b），每个开关矩阵（8a，8b）被组合，使得每个开关矩阵（8a，8b）有助于每个输出端口的可用输出功率。因此，开关矩阵（8a，8b）中的一个或其中的一个传输路径的故障将仅导致相关输出端口处的输出功率的小幅减少，而不是如完全的功率损耗对于常规开关，可以使用开关矩阵组合器中的功率不平衡检测电路来检测故障状况。此外，已经由电力不平衡检测电路检测到的故障状况可以由自动电平控制系统临时补偿。

摘要： A method of transmission of radio signals over all types of graded-index multimode fibre is provided. The method comprises launching optical radiation into the core of the multimode fibre away from the centre of the core so as to strongly excite a subset of the available modes of the multimode fibre. The subset of modes excited are within a small number of mode groups and thus have similar propagation constants leading to a reduction in modal dispersion and modal interference and smoothing of the frequency response passband region beyond the fibres specified 3dB base band bandwidth assisting RF transmission and recovery from this region.

摘要： The invention relates to the generation of radio frequency modulated optical radiation, in particular for use in a radio over fibre communications system. It has been found that a semiconductor electroabsorption modulator can efficiently modulate an input optical signal at harmonics of the electrical modulation frequency applied to the electroabsorption modulator. A low frequency design, and thus low cost, electroabsorption modulator can be utilised to generate higher order harmonics of an electrical drive signal for use in a radio over fibre communications system.

摘要： A high speed optical switching device (1) comprises a waveguide arrangement, incorporating a pn junction, with a large bondpad (11) for the purposes of increasing the capacitance presented by the device. Data and control signals can be input at an input port (8) of the waveguide arrangement, presence of the control signal operating to modify the optical path length of the device for the data signal. By incorporating the device in an interferometer arrangement, or by exploiting a Fabry-Perot cavity of the device, it can be used to transmit the data signal selectively, for instance so as to demultiplex a time multiplexed optical communications signal. The high capacitance provides very short recovery times so that data rates of 10 GHz and substantially above can be accomodated.
