摘要： PURPOSE: To eliminate dependency on wavelength and to obtain a specified attenuation quantity regardless of the wavelength of light by blending a dopant to more largely attenuate transmitted light for shorter wavelength of light signals in an optical fiber. CONSTITUTION: This optical attenuator 5 has a columnar coupling part 5A and internally has a cavity 5B existing at the center thereof. The part of the cavity 5B has a bend imparting part 8. Both ends of the optical fiber 7 are arranged, fitted and fixed to the center of the coupling part 5A. Vanadium V is incorporated as the dopant into the optical fiber 7 and two kinds of the light signals of the different wavelengths are inputted therein from one end and an adjusting screw 13 is adjusted so that the output levels of both are nearly equaled to each other. Namely, the light signals of the longer wavelength are more largely attenuated if the specified bend is imparted on the optical fiber 7 but if the dopant to more largely attenuate the transmitted light of the shorter wavelength is blended in the optical fiber 7, the light signals of the short wavelength and the light signal of the long wavelength are nearly uniformly attenuated when viewed over the entire part of the optical fiber 7.

摘要： PURPOSE: To obtain a constant attenuation quantity regardless of wavelengths of light signals by eliminating the wavelength-dependency of a light attenuator using dopants. CONSTITUTION: An optical fiber of a mode field diameter most suitable to the wavelengths of the light signals to be transmitted is obtd. by adjusting the refractive index distribution and core diameter, etc., of a single mode fiber. The light signal of the shorter wavelength receives the higher attenuation than the light signal of the longer wavelength if the mode field diameter is so selected as to be adaptable to the light signal of the longer wavelength out of the light signals of two kinds of the wavelengths to be inputted to the light attenuator. On the other hand, the dependency of the light attenuation characteristic on the wavelengths occurring in the selection of the mode field diameter is offset if the dopant to more largely attenuate the transmitted light of the longer wavelength of the light signals is incorporated into the optical fiber 5 shown in the Fig. As a result, the light attenuation characteristics to the light signals of >=2 kinds of the different wavelengths λ1, λ2 are made nearly equal to each other.

摘要： PURPOSE: To obtain a constant attenuation quantity regardless of wavelengths of light signals by eliminating the wavelength-dependency of using dopants on. CONSTITUTION: The light signal of a shorter wavelength propagates more concentrically at the center than the light signal of a longer wavelength when an optical fiber 5 is viewed in its cross-section. If the dopant to more largely attenuate the transmitted light of the longer wavelengths of the light signal is incorporated into the axial core part of the optical fiber 5, the light signals of the shorter wavelength receiver higher influence of the dopant than the light signals of the longer wavelength. Then, the attenuation effect of nearly the same degree is given to the signals of the longer wavelength and the signals of the shorter wavelength when viewed from the entire part of the cross-section of the optical fiber 5.

摘要： PROBLEM TO BE SOLVED: To provide a method to manufacture a low OH group optical waveguide. SOLUTION: In the manufacturing method of an optical waveguide, a porous glass layer 2 which becomes a core is deposited on a substrate 1 and the porous glass layer 2 which becomes the core is made into a glass to form a core 6. Then, a porous glass layer 7 which becomes a clad is deposited around the core 6 and the porous glass layer 7 which becomes the clad is made into a glass to form a clad 10. In the above step, the porous glass layer 2 which becomes the core and the porous glass layer 7 which becomes the clad are heated in a deuterium environment to substitute an OH group for an OD group so as to reduce the OH group content and a dehydrating process is conducted prior to making the glasses or at the same time of the glass making when the layer 2 which becomes the core and the layer 7 which becomes the clad are made into the glasses. It is also acceptable to combine equal to or more than two steps of the deuterium process or the dehydrating process. Since the deuterium process and the dehydrating process are conducted in the steps in which the core and the clad are formed for the optical waveguide, a high quality optical waveguide, which has a very small OH group content and is suitable for wavelength multiplexed communication, is manufactured.

摘要： PURPOSE:To correct the loss of a transformer when a load resistor is changed by connecting a low voltage end of the primary side of the transformer to a noninverting input terminal of a negative feedback amplifier and connecting the noninverting input terminal to ground via a resistor for detecting a load current. CONSTITUTION:The negative feedback amplifier circuit 1 consists of an amplifier A, a transformer To, a signal source ei, an input resistor Rg, a feedback resistor Rf and a load resistor RL. Then one terminal of the primary winding of the transformer To is connected to a noninverting input terminal a2 of the amplifier A, and the noninverting input terminal a2 is connected to ground via a resistor Rn. Thus, the impedance of the feedback amplifier circuit 1 is increased as the load resistor RL at the secondary side increases, the voltage induced in the resistor Rn is decreased and no positive feedback is substantially caused, but when the load resistor RL is decreased, the impedance is decreased and an output voltage Eo is increased. Thus, the loss of the transformer To is corrected without being affected by the fluctuation of the load resistor RL to keep the stable operation.

摘要： PROBLEM TO BE SOLVED: To provide a cable with a terminal facilitating inspection at connection work or at the completion. SOLUTION: This cable is machined according to a installation place and provided with the connecting terminal 14, in advance. An IC tag 18 recording status information indicating an installation status at the installation place is mounted at an arbitrary part of the cable.
