Description
technical fieldthis practicality belongs to optical time domain reflectometer measuring techniques for optical fiber field, relates to a kind of test optical fiber device.
background technologyduring Cable's Fault, need to position test with OTDR instrument (optical time domain reflectometer), OTDR instrument is in actual measurement process, there is test blind area (distance is generally between 30 meters-80 meters), be that OTDR instrument is directly connected with testing fiber, if test starting point and actual fault point position are within 80 meters time, will make testing fiber state display waveform drop in the front end blind area of OTDR curve, so the curve of this segment distance can not accurately reflect actual fiber situation, can have a huge impact test optical fiber effect, thereby can incur loss through delay the location of fiber failure point and repair in time.
summary of the inventionthe purpose of this utility model is to solve the inaccurate technical problem of test blind area fiber failure point location that prior art exists, and a kind of test optical fiber device is provided.
To achieve these goals, the utility model test optical fiber device, on the basis of the optical time domain reflectometer of prior art, to have installed an add-on module additional to form, its main points are that it comprises optical time domain reflectometer and gets by the 12 core optical cables of a section 25 meters the transition optical fiber of a section 300 meters that head and the tail welding forms after core, the transition optical fiber of described 300 meters is wrapped on the roller of two ends band rotating disk, fusion splice after the welding of described optical fiber head and the tail is arranged in optical fiber continued access box, described optical time domain reflectometer is connected with optical fiber continued access box by optical cable, described optical fiber continued access box is fixedly connected with roller rotating disk by connecting screw.
The utility model reasonable in design, novelty, get head and the tail welding after core and form the transition optical fiber of a section 300 meters by one section of 12 core optical cable by 25 meters is set, and evidence can effectively avoid testing blind area; Fine continued access box for the welding of optical fiber head and the tail after the safety of joint place; Roller, for the winding of optical fiber, is easy to carry.The utility model has solved the inaccurate technical problem of test blind area fiber failure point location that prior art exists, and greatly improves the accuracy rate of short distance test optical fiber.
accompanying drawing explanationaccompanying drawing is the utility model structural representation.
In figure 1, optical fiber continued access box 2, transition optical fiber 3, roller 4, connecting screw 5, fusion splice 6, optical time domain reflectometer
embodimentwith reference to accompanying drawing, it comprises the utility model optical time domain reflectometer 6 and gets by the 12 core optical cables of a section 25 meters the transition optical fiber 2 of a section 300 meters that head and the tail welding forms after core, the transition optical fiber 2 of described 300 meters is wrapped on the roller 3 of two ends band rotating disk, fusion splice 5 after the welding of described optical fiber head and the tail is arranged in optical fiber continued access box 1, described optical time domain reflectometer 6 is connected with optical fiber continued access box 1 by optical cable, and described optical fiber continued access box 1 is fixedly connected with roller rotating disk by connecting screw 4.
When the utility model is made, take after the 12 core optical cables of a section 25 meters are got core and be wrapped on roller after the head and the tail welding of continued access box the inside, middle by punching by the fixing overall structure that forms test optical fiber device of screw.
The utility model is to increase by one section of transition optical fiber on the basis of original optical time domain reflectometer, makes to test within blind area drops on transition optical fiber, thereby avoids the test blind area of optical time domain reflectometer, effectively raises the accuracy rate of short distance test.
