Title: Optical system
Inventor: DELAVAUX JEAN-MARC PIERRE
IPC: H04B10/29
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To obtain an optical amplifier which amplifies input light polarized into two orthogonal polarization directions and which solves a hole burning problem. SOLUTION: An optical system 10 which amplifies an optical message signal is provided with at least one amplification section a1 (e.g. a doped optical fiber). One end of a polarization-dependent optical isolator 12 is connected to the amplification section a1 by a first polarization-maintaining optical fiber 13, and the other end is connected to a second polarization-maintaining optical fiber 11 which receives the optical message signal. The polarization-maintaining optical fibers are matched with the isolator 12 so as to pass the optical message signal which comprises polarization components in a plurality of directions.  Alternatively, two amplification sections a1 , a2 are installed, a Faraday rotator 81 is arranged between them, and the polarization state of a pumping signal which propagates the amplification section on one side is set at right angles to the polarization state of a pumping signal which propagates the amplification section on the other side.

Title: Laying structure for flexible pipeline and laying method thereof
Inventor: KAKIZAKI JIRO
IPC: F16L3/22
Filed: 1994-03-25
Abstract: PURPOSE:To prevent an excessive stress from being exerted on a support point of a flexible pipeline by making it possible to lay the flexible pipelines in a multiple layer manner. CONSTITUTION:Struts 12 are vertically disposed in an underground pit 10. In the struts 12, support arms 16 are fixed movably along the struts 12. Support frames 20 are fixed to the support arms 16, thus supporting at the surfaces thereof flexible pipelines 22 to be laid. Accordingly, since the support frame 20 supports the flexible pipeline 22 not at a point but at the surface, force to be exerted on the support portion of the flexible pipeline 22 is not concentrated, thereby preventing breakage. Moreover, the plurality of support arms 16 are fixed to the struts 12 so that the flexible pipelines 22 can be laid in a multiple layer manner.
