摘要： An optical access network (5) comprises an optical network unit (20) having a first port (21) for connecting to a first optical link (31), a second port (22) for connecting to a second optical link (32) and an optical source (23). The optical source (23) is arranged to generate a first optical signal, to transmit the first optical signal via the first port (21), to receive an optical seed signal via the first port (21) and to amplify the optical seed signal. The optical seed signal has a narrower bandwidth compared to the first optical signal. A modulator (25) is arranged to modulate the amplified optical seed signal with upstream data to form an upstream optical signal and to transmit the upstream optical signal via the second port (22). A polarisation modifier (50) can modify polarisation of the first optical signal.

摘要： A broadcast and select ring network for optical WDM communicationincludes two parallel fiber rings (1a, 1b) carrying traffic in oppositedirections between nodes (3; A, B, C, D). The nodes comprise on their receive side selecting means such as a cross connect device (21) or similar means allowing a flexible selection of the wavelength channels which are to be received by each node. Thereby, any WDM channel in the rings can be selected and received in the nodes. For example, all nodes can receive signals in the same channel for e.g. set up or reconfigurationpurposes. Furthermore, the number of receivers in a node can be smallbut still all channels can be received. The number of transmitters in eacha node can also be small since every transmitter can reach every receiver.

摘要： The invention relates to the implementation of multiplexing and demultiplexing of optical signals. The multiplexing and demultiplexing are carried out by using the same waveguide phased array component (WGA). On the first side, the component comprises at least an input port and an output port (IG, OG), and on its second side a first group of ports that constitute the demultiplexer function output ports, and a second group of ports that constitute the multiplexer function input ports. An optical input signal is applied to the input port, such an input signal comprising a number of signals each at its own wavelength, the input signal is demultiplexed in the component and the demultiplexed signals are coupled to ports of the first group. The signals to be multiplexed are applied to ports of the second group and the multiplexed signal is coupled to the output port (OG). To reduce crosstalk, the signals at different wavelengths and the signals to be multiplexed are demultiplexed and applied, respectively, to alternate second side (B) ports so that the second side ports alternately have a port belonging to the first group and a port belonging to the second group.

摘要： In general, techniques are described for automatically configuring fiber cross-connects between customers of an interconnection facility. In some examples, a programmable network platform for an interconnection facility exposes an interface by which customers of the interconnection system provider may request fiber cross-connects to other customers of the interconnection system provider. The programmable network platform may, in response to a request for a fiber cross-connect, configure an optical switch fabric of the interconnection facility network infrastructure to create a fiber cross-connect between the demarcation points for the customers to be interconnected.

摘要： A wavelength selective switch is realized by combining a quantized dispersion element and an array of switching means. The quantized dispersion element enables to concentrate all the wavelengths within predetermined wavelength bands onto the same location in the switching array. With this arrangement, a low fill factor switching array can be used while maintaining good flat-top spectral performance with no spectral dips and improving alignment tolerances.

摘要： A multi-wavelength or white-light optical switch including an array (204) of mirrors (260) tiltable about two axes, both to control the switching and to provide variable power transmission through the switch, both for optimization and for power equalization between wavelength channels in a multi-wavelength signal. The output power of a channel is monitored (210, 212, 218), thereby allowing feedback adjustment (220) of the transmitted power. The mirrors are preferably formed in a micro electromechanics system array to be tiltable in orthogonal directions (266, 272) and having electrostatically controlled tilting by two pairs of electrodes (274, 276) beneath the mirrors (270). Input power of the separate channels may also be monitored (242, 244, 218).

摘要： An optical cross connect (100), especially a wavelength cross connect, using free-space optics (106, 114, 116), a diffraction grating (108), and a micro electromechanical systems (MEMS) array (122) of movable mirrors (128). A concentrator (104) receives light from widely separated optical fibers (170) and brings the beams together into a more closely spaced linear array. Free-space optics process all the beams. Front-end optics (106) collimate the beams from the fibers and flatten their fields. The diffraction grating (108) spectrally separates each beam into sub-beams. A long-focus lens (114) focuses the sub-beams onto the 2-dimensional MEMS array (122). A fold mirror (124) reflectively couples two such mirrors, whereby the switched signals propagate back through the same optics and are spectrally recombined onto the fibers. Other embodiments include white-color cross connects, multiple MEMS arrays, and parallel optics. Power dividers (272) or wavelength interleavers can divide signals from the fibers, and multiple cross connects (276a, 276b) switch different wavelength groups.
