Any one of the OSIS includes a receiving sub-module, an output sub-module, an interconnection fabric module and an optical switching sub-module. The receiving module is configured to receive multiple first and third upstream optical signals from first and second Optical Add-Drop Sub-systems (OADS) corresponding to the first and the second pods. The output sub-module is configured to output multiple second and fourth downstream optical signals to the first and second OADS. The interconnect circuit sub-module is configured to connect adjacent two of the OSISs and any two of the OSISs transmit a corresponding lateral transmission optical signal via a first line correspondingly. The optical switching sub-module is configured to transmit optical signals between the receiving sub-module, the output sub-module, and the interconnection fabric module.

Abstract: An example system includes an optical modulator and a multiplexing controller. The modulator includes a data bus for receiving at least one data signal, a plurality of multiplexers and a plurality of modulating segments. Each multiplexer is coupled to the data bus to receive at least one data signal and to output a multiplexed signal. Each modulating segment may receive the multiplexed signal from one of the plurality of multiplexers and modulate the multiplexed signal using an optical input. The multiplexing controller may be in communication with the plurality of multiplexers and may configure each of the plurality of multiplexers in accordance with a selected modulation type.

Abstract: A large-span and special-shaped arch bridge, comprising a main girder (2), a center abutment (11) served as a central bearing point and two auxiliary abutments (12,13) served as bearing points at two ends, wherein further comprising an arch-axis combination (3) and two arch-axis bending beams (4,5) presented as arcs projected upwards, the arch-axis combination being built on the center abutment (11) with two ends connected to the inner ends of the two arch-axis bending beams (4,5), the outer ends of the two arch-axis bending beams (4,5) being built on the two auxiliary abutments (12,13), the two arch-axis bending beams (4,5) being connected to the main girder (2) via a plurality of inhaul cables. A method for constructing said arch bridge is also disclosed.

Abstract: A method and apparatus for adjusting the live and dead load balance between the arches of an arch bridge and the truss girder that supports the bridge deck. The method is achieved by providing hanger rods disposed between the arches and the top chords of the truss girder whose compression may be adjusted. In which the arch truss counter act the compression in the top chord of the truss. This interaction adds to the strength and safety of both elements of the structure. With this interaction there are no critical members which can cause catastrophic failure of the bridge by failing. By combining two of these bridges side by side, and then connected with the lateral members, both at top and bottom chord of trusses, it is possible to carry vehicular, train, and pedestrian lanes separated and accommodated with safety; all without a critical member.

Abstract: The invention relates to a traffic installation having at least two traffic routes arranged one above the other, which each comprise at least one traffic area, which traffic area is completely enclosed at least over a certain length, the enclosure having at least one transparent element allowing a view out of the enclosure.

The method is achieved by providing a tension equalizing member across the bottom chord of the truss girder whose tension may be adjusted in cooperation with tension adjustments of hanger rods disposed between the arches and the bottom chords of the truss girder.

Abstract: A lattice bridge construction system is characterised by the provision of lattice panels (A,B,C) which are of substantially identical length but of different depths relative to one another such that when variously combined one with another, with or without additional reinforcement, trusses having considerably more economic increments of bending strength may be achieved.

Abstract: The useful life and carrying capacity of an existing steel truss bridge are increased by adding a support arch assembly secured to the truss structure. In the preferred embodiment the support arch structure assembly includes arch members running along each side of the bridge. Each arch member includes two spaced arch sections, each arch section including end-to-end beams, preferably channel beams, forming an arcuate path. The web portions of the arch beams are secured to hangers of the truss structure, one arch section extending on the inboard side of the hangers, the other section extending on the outboard side. Additional floor beams may be added, along with corresponding additional hangers which can be secured to the arch beams. The support arch assemblies may be post-tensioned by tension bars connected between opposite ends thereof.
