PROBLEM TO BE SOLVED: To provide an apparatus for producing optical fibers without any defects such as insufficient admission of a polymer for a sea part among the adjacent wing materials, melt sticking of the wing materials and the inability to produce the prescribed optical fibers when producing...
Even though this is considerably lower for this cable when compared with other media. In fiber optic, the transmission can be done in two modes like single-mode and multi-mode. But, attenuation can occur in both the transmission modes. So this can be avoided by maintaining enough light in ...
Hollow optical fiber and its production manner To provide a hollow optical fiber that can transmit long wavelength laser light at a low loss and can be formed into a long fiber through a relatively simple process and to provide a method for manufacturing the optical fiber. SOLUTION: ... 井本...
PURPOSE: To obtain an optical fiber having an end reflection mirror improved in durability by subjecting the end at the core end of an optical fiber together with an adapter to end face polishing and forming a light reflection film at the polished end face. ;CONSTITUTION: After a projective ...
PROBLEM TO BE SOLVED: To simplify the work to pass a continuous optical fiber unit through plural pieces of tubes laid in a longitudinal direction and to form the extra length of the optical fiber unit between these tubes. ;SOLUTION: This method consists in holding and connecting a disassemb...
CONSTITUTION:A clad material 9 melted in a crucible 10 is coated on a crystal fiber 1 of core formed by melting the core material 5 in the crucible 4 and drawing this, whereby a crystal fiber 6 is formed. Further a molten resin 12 in a crucible 13 is coated thereon to form a ...
Optical fiber cable and its production manner 优质文献 相似文献OPTICAL SEISMIC SENSOR SYSTEMS AND METHODS Disclosed is an optical seismic sensor system for measuring seismic events in a geological formation, including a surface unit for generating and processing an optical signal, and a sensor device ...
An infrared light transmitting optical fiber and a process for producing the same are disclosed. The infrared light transmitting optical fiber is produced by a process comprising preparing a core crystalline fiber having a high melting point and a high refractive index, forming around the core fiber...
PURPOSE: To provide an optical fiber cable with which the suppression of skew is possible and the efficiency of cable laying and connection work can be im proved. ;CONSTITUTION: Plural pieces of plural-fiber optical fiber assemblies 1 are arrayed in a lateral direction and are arranged apart pr...
PROBLEM TO BE SOLVED: To provide the optical fiber cord which holds a wire material for reinforcement at a specific position of the outer periphery of a coated optical fiber and prevents the partiality of the arrangement. ;SOLUTION: The ribbon-shaped reinforcing body 22 is used which has reinfo...
