Abstract
The utility model provides a glass large-core-diameter optical fiber with a monitoring point. According to the utility model, a gap used for detecting information is reserved on the glass large-core-diameter optical fiber; a collection-used optical fiber or optical detector, which is used for collecting information, is arranged in the gap; and the glass large-core-diameter optical fiber and the collection-used optical fiber or optical detector are fixedly connected with a shielding box through an optical fiber fixing device. The glass large-core-diameter optical fiber provided by the utility model has the beneficial effects that the glass large-core-diameter optical fiber is provided with the gap, and the gap is internally provided with the collection-used optical fiber or optical detector which is used for collecting information of the glass large-core-diameter optical fiber in real time; the accuracy of optical fiber information detection is improved; the glass large-core-diameter optical fiber and the monitoring point are on the same optical fiber, thereby reducing damages on the optical fiber, and improving the reliability and safety of the optical fiber; the glass large-core-diameter optical fiber is provided with the shielding box which can shield external stray light interference, thereby enabling measurement data to be accurate; and the position of the monitoring point can be chosen freely by a user.
Description
Technical field
The utility model relates to glass large-core optical fibers, particularly with the glass large-core optical fibers in monitoring point.
Background technology
Optical fiber is one of human great scientific and technological invention in last century, achievement in research as hi-tech, it not only is widely used in each Disciplinary Frontiers of scientific research, and in the mankind's production, the life aspect has obtained a large amount of application, the whole world forms the output value that surpasses hundred billion dollars, as glass large-core optical fibers, along with the transmission of laser energy grows up, time is late than telecommunication optical fiber, many incomplete places are arranged, such as the real-time measurement of optical fiber energy, existing technology is the power of laser instrument to be used as the fiber power of glass large-core optical fibers, and such method error of measuring is larger.
The utility model content
The purpose of this utility model provides a kind of glass large-core optical fibers with the monitoring point, is provided with the monitoring point at glass large-core optical fibers, detects in real time the information of glass large-core optical fibers, improves the accuracy that glass large-core optical fibers information detects.
The technical solution adopted in the utility model is: described a kind of glass large-core optical fibers with the monitoring point, it is characterized in that: have a breach for detection of information on the described glass large-core optical fibers, the collection that is provided with Information Monitoring in the described breach is with optical fiber or photo-detector, and described glass large-core optical fibers and gathering all is fixed together by optic fibre fixing device and shielding box with optical fiber or photo-detector.
Effect of the present utility model is: be provided with breach at glass large-core optical fibers, the collection that is provided with Information Monitoring in described breach comes the information of real-time collection glass large-core optical fibers with optical fiber or photo-detector, improve the accuracy that optical fiber information detects, glass large-core optical fibers and monitoring point are on an optical fiber, the optical fiber damage is little, reliability and the security of optical fiber have been improved, be provided with shielding box, can shield external light disturbance, make the data of measurement accurate, and the position in monitoring point can be chosen at random by the user.
Description of drawings
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Among the figure: the 1-glass large-core optical fibers, 2-gathers with optical fiber or light detection device, 3-breach, 4-shielding box, 5-optic fibre fixing device.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Referring to accompanying drawing, described a kind of glass large-core optical fibers with the monitoring point, it is characterized in that: have a breach 3 for detection of information on the described glass large-core optical fibers 1, the collection that is provided with Information Monitoring in the described breach 3 is with optical fiber or photo-detector 2, and described glass large-core optical fibers 1 and gathering with optical fiber or photo-detector 2 all is fixed together by optic fibre fixing device 5 and shielding box 4.
Erode away a very little breach with hydrofluorite at glass large-core optical fibers, be provided with in the breach and gather with optical fiber or photo-detector, with shielding box breach is shielded with the front end and the external world that gather with optical fiber or photo-detector, form a monitoring point, monitoring point and glass large-core optical fibers are on an optical fiber, the damage of optical fiber is very little, reliability and the security of optical fiber have been improved, gap position can be random selection, the position in monitoring point also just can choose at random according to user's idea, very convenient, be provided with shielding box, can shield the interference of external veiling glare, the data of measuring are reliable, accurately, optic fibre fixing device is with glass large-core optical fibers and gather with optical fiber or photo-detector and shielding box and fix, reduce the error that produces because of the movement of optical fiber, the information of the detection glass large-core optical fibers that whole monitoring point energy is real-time, can improve the accuracy that glass large-core optical fibers information detects, because breach is very little, so it is very little to gather the laser power that gathers with optical fiber or light detection device, the insertion loss of glass large-core optical fibers is also with regard to very little (less than 1%).
