The invention discloses an optical fiber anti-monitoring device and an optical fiber box employing the same. The optical fiber anti-monitoring device comprises an optical fiber limiting channel for mounting an optical fiber, and further comprises a dowel pin for limiting sliding of the slide part, wherein the optical fiber limiting channel extends in the rectilinear direction; a slide piece capable of driving the optical fiber to bend is slidly arranged in the middle of the optical fiber limiting channel; a spring capable of driving the slide piece to slide is connected to the slide piece. According to the scheme adopted by the invention, when the optical box is opened, the dowel pin is separated from the slide part, the slide part horizontally slides under the action of the spring so as to push the optical fiber to generate a certain amount of bending deformation; after the optical fiber is bent, energy of a light signal transmitted in the optical fiber changes correspondingly; a far end (a monitoring end) can be used for judging whether the optical box is opened or not according to signal changes of the optical fiber; when the optical box is opened abnormally, relevant staff can quickly respond to prevent monitoring.
Description
technical field [0001] The invention relates to the technical field of remote optical fiber anti-eavesdropping, in particular to an optical fiber anti-eavesdropping device and an optical fiber box using the device. Background technique [0002] The optical fiber equipment in the prior art is not provided with an anti-tapping device, which cannot meet the requirement of remote monitoring whether the optical fiber box is opened, that is, anti-tapping. Contents of the invention [0003] A brief overview of the invention is given below in order to provide a basic understanding of some aspects of the invention. It should be understood that this summary is not an exhaustive overview of the invention. It is not intended to identify key or critical parts of the invention nor to delineate the scope of the invention. Its purpose is merely to present some concepts in a simplified form as a prelude to the more detailed description that is discussed later. [0004] The invention pro...
