IPC: H04B10/2507
Filed: 1989-12-25
Abstract: PURPOSE:To obtain this bidirectional optical amplifier which can amplifier the light signal to be bidirectionally propagated by introducing the reflected light generated in an optical fiber for output of an optical circulator having 4 ports to serve as input/output terminals for light through the optical circulator to an optical fiber having a non-reflection terminal. CONSTITUTION:The exciting light from a light source 12 for exciting passes the ports A, B of the optical optical circulator 10 and is inputted to the optical fiber L10 added with a rate earth element, by which the optical fiber L10 is excited. The light signal propagated in the optical fiber L10 is amplified in this way. The light signal inputted from the optical fiber l12 in the exciting state passes the ports A, B of the optical circulator 10 and is amplified during the propagation in the optical fiber L10. On the other hand, the light signal is amplified when the light signal advances in a direction 211 in the optical fiber L10 in the exciting stage. This amplified signal passes the ports B, C and the noise light is removed by an optical filter 13. The reflected light passes the ports C, D and advances to the optical l16 when a reflection is generated by the optical filter 13. Since the terminal thereof is the non-reflection terminal, the reflected light does not return to the optical fiber L10.

Abstract: PROBLEM TO BE SOLVED: To economically constitute an optical path network without increasing the scale of an optical cross connector by grouping the optical path of a part of optical path network data obtained by assigning one wave length to one piece of optical path into halves and assigning a new wave length to one of them. SOLUTION: As routes connecting nodes 1 to 6, there are an optical path 6 one wave length are assigned to, optical paths P13 and P14 obtained by dividing the optical path 6. An optical path controller 61 controls the combination of transmission lines and the wave length of an optical signal transmitted within this transmission line to constitute an optical path. This optical path controller 61 monitors the state of using a wave length within an optical path within an optical transmission line between the respective nodes and within an optical path between the optical cross connector and an optical terminating equipment to temporarily terminate a part of the optical paths at a node in the middle to bi-sect.  In this case the optical path controller 61 does not increase the number of optical paths between each optical cross connector and the optical path terminating equipment and assigns another wave length to one optical path of the bi-sected optical path.

Abstract: PROBLEM TO BE SOLVED: To facilitate a preparatory work at the time of use or a clearing work at the time of storage by providing a leg part, a wall finishing material support means and a receiving tray support means connected to each other and integrally interlocked so that the whole assembly becomes deformed. SOLUTION: A cross bracket 11, a tray bracket 13 and each pair of front and rear legs 8a, 8b form a linkage mechanism. If the legs 8a, 8b are deformed from a used state to a folded state, both cross bracket 13 and tray bracket 13 are integrally interlocked to rotate forward. When set to this folded state, the legs 8a, 8b, the cross bracket 11 and the tray bracket 13 are suspended against a pedestal part 9. Further, the right and left leg parts 8 are deformed in such a state that each of the leg parts 8 falls to the rear face side of the pedestal part 9 by rotating a second rotating shaft on which a second mounting plate 44 is pivotally supported, with the second rotating shaft acting as a rotating center, from the folded state. Consequently, the right and left leg parts 8, the cross bracket 11 and the tray bracket 13 are set to a stored state.  Thus the step to remove each of the, members is no longer required.
