Abstract
The utility model discloses an on-line detection connection optical matching unit which comprises a connector box body, wherein a closed stainless steel device is connected outside the connector box body, an optical fiber coupler flange and a double-end tail fiber are installed in the closed stainless steel device, a sealing channel is arranged between the connector box body and the closed stainless steel device, an optical fiber is respectively led out from optical cables at two ends, which are welded in the connector box body, and the optical fibers are connected and fixed on the flange through the tail fiber in the closed stainless steel device through the sealing channel. The on-line detection splicing optical distribution unit can be used for selectively opening the sealed stainless steel device at regular intervals, testing the optical cable attenuation by using the optical fiber in the device, tracking the optical cable attenuation curve of the joint box, and arranging a maintenance plan and opening a box for inspection in time when the optical cable attenuation curve of the joint box is found to be abnormal. The detection mode is time-saving and labor-saving, the working difficulty is effectively reduced, the optical fiber and the joint box cannot be damaged in the operation, and the sealing performance of the joint box cannot be influenced.
Description
Technical Field
The utility model relates to the technical field of optical communication, in particular to an on-line detection splicing optical matching unit.
Background
The optical cable joint box connects two or more optical cables together, has a splicing part for protecting components, is free from the influence of external environment, keeps stable and reliable operation state, is necessary to be adopted in the construction of optical cable line engineering, and is one of very important equipment. The optical cable joint box has strict sealing performance requirements, but because the influence of ambient temperature in the use, takes place expend with heat and contract with cold, the sealing strip also can be ageing, and the sealed face of optical cable joint box can produce small clearance, and external moisture and rainwater enter into the optical cable joint box easily to influence the communication quality and the life of optical cable line.
Because the optical fiber core cannot be reflected on the optical power attenuation immediately after being affected with damp or soaked in water, the comparison of the attenuation of the front test and the rear test cannot be used as the judgment basis for the box opening inspection, and the conventional optical cable joint box is not provided with a detection device at present, so that a maintainer cannot determine whether the optical cable is affected with damp or not when maintaining and inspecting the optical cable joint box, once the attenuation value is increased greatly, the optical cable is damaged irreversibly, only the damaged optical cable can be cut off, or even the whole optical cable is replaced, and the adverse effect on the communication safety is brought.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an on-line detection connection optical distribution unit aiming at the defects of the prior art, and solves the problem that the damage of an optical fiber cannot be detected in time.
In order to solve the technical problems, the technical scheme adopted by the utility model is as follows: the utility model provides an on-line measuring light that continues joins in marriage unit, includes the splice box body, and this external airtight stainless steel device that is connected with of splice box, install fiber coupler ring flange and double-end tail optical fiber in the airtight stainless steel device, be equipped with sealed passageway between splice box body and the airtight stainless steel device, follow respectively draw forth an optic fibre in the butt fusion's in the splice box body both ends optical cable, through sealed passageway passes through in the airtight stainless steel device the tail optical fiber is connected and is fixed on the fiber coupler ring flange.
