Description
technical field
[0001] The invention relates to the technical field of optical fiber cable production, in particular to an automatic disconnection detection device for communication optical fiber cable production. Background technique
[0002] Fiber optics are similar to coaxial cables, except without the mesh shield. In the center is the glass core for light propagation. In a multimode optical fiber, the diameter of the core is 15 mm to 50 mm, which is roughly equivalent to the thickness of a human hair. The diameter of the single-mode fiber core is 8 mm to 10 mm. The core is surrounded by a glass jacket with a lower refractive index than the core to keep the fiber inside the core. On the outside is a thin plastic jacket to protect the envelope. Optical fibers are usually bundled and protected by a jacket. The fiber core is usually a double-layer concentric cylinder with a small cross-sectional area made of quartz glass. It is brittle and easy to break, so an additiona...
