Abstract: PURPOSE:To branch/synthesize another signal which is waveform-multiplexed with a main signal so that a high S/N rate can be obtained without being affected by the main signal by simultaneously branching the optical signal which is waveform- multiplexed and synthesizing exciting light to branching light. CONSTITUTION:The main signal is loaded on a 1.55mum-band and a monitor control signal on the optical signal of a 1.347m-band, for example, so as to transmit them on an optical fiber transmission line 8.

The main signal is light-amplified by excitation by inputting the exciting light of the 1.48mum-band to the terminal (4) of the coupler 1. On the other hand, the control signal is converted into an electric signal in the element 5, is monitor-controlled and amplified in an electric circuit 6 and is electrically/optically converted into the original wavelength band in a light- emitting element 7. Furthermore, the main signal which is inputted to the terminal (4) of a WDM coupler 3 and is amplified in an amplifier 2 is synthesized with the control signal in the terminal (2) so as to output it again to an optical fiber 9.

Abstract: PURPOSE:To prevent core yarns from being damaged by a method wherein prepreg is made of composite yarns produced by coveringly winding sleeve yarns round the core yarns, which is a thread bundle containing substantially untwisted and paralleled inorganic fiber filaments.

As core yarns, combined filament yarns of said inorganic fiber filaments and high strength and high elasticity filaments made of ultra-high-molecular-weight polyethylene fibers or the like are preferable from the view point for improving impact resistance. As sleeve yarns to cover the core yarns, any yarns, which can hold untwisted core yarns in the form of a bundle, will do and concretely filaments consisting of synthetic fibers made of nylon 6, nylon 66, polyester or the like can be used. Since the core yarns are covered with the sleeve yarns, the composite yarn prepreg can prevent the inorganic fiber filaments from being damaged in the resin impregnating process.
