Description
Technical Field
The invention relates to the field of optical cables, in particular to a fixed-point hardening type bending-resistant optical cable sheath.
Background
Optical fibers are short for optical fibers, and are fibers made of glass or plastic that can be used as a light conducting means. The principle of transmission is "total reflection of light". The fine optical fiber is enclosed in a plastic sheath so that it can be bent without breaking. Generally, a Light Emitting Diode (LED) or a laser beam is used as a transmitter at one end of the optical fiber to transmit an optical pulse to the optical fiber, and a photosensor is used as a receiver at the other end of the optical fiber to detect the pulse. In daily life, optical fibers are used for long distance information transmission because the loss of light transmitted through optical fibers is much lower than the loss of electricity transmitted through electric wires.
In general, the terms optical fiber and optical cable are to be confused. Most optical fibers must be covered by several layers of protective structures before use, and the covered cables are referred to as fiber optic cables. The protective layer and the insulating layer on the outer layer of the optical fiber can prevent the surrounding environment from damaging the optical fiber, such as water, fire, electric shock and the like.
The optical cable is divided into: cable sheath, aramid fiber silk, buffer layer and optic fibre. Optical fibers are similar to coaxial cables except that the mesh shielding is absent. The center is the glass core through which the light propagates. In the multimode optical fiber, the core diameter is 50 μm and 62.5 μm, which are approximately equivalent to the thickness of human hair. Whereas the diameter of the single-mode optical fiber core is 8 μm to 10 μm, 9/125 μm is generally used. The core is surrounded by a glass envelope, commonly referred to as a cladding, of lower refractive index than the core, which keeps the light rays within the core. Further on the outside is a thin plastic outer jacket, i.e. a coating, for protecting the cladding. The optical fibers are typically bundled and protected by an outer jacket.
The core is typically a double-walled concentric cylinder of small cross-sectional area made of quartz glass, which is brittle and easily broken. Although the surface of the optical cable is wrapped with protective layers such as cable sheath, aramid fiber yarn and buffer layer, when the optical cable is subjected to bending force from the outside, local stress is too concentrated and overlarge, the fiber core at the stress position is easy to crack, the damage rate is high, and the material waste condition is relatively serious.
