Description
Technical Field
The invention belongs to the technical field of optical fibers, and particularly relates to a multimode optical fiber with reliable connection.
Background
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 not present. 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. Surrounding the core is a glass envelope, commonly known as a cladding, of lower refractive index than the core, which keeps the light within the core and on the outside is a thin plastic outer jacket, the coating, which protects the cladding. The optical fibers are typically bundled and protected by an outer jacket. The fiber core is a double-layer concentric cylinder which is usually made of quartz glass and has a small cross section area, is fragile and easy to break, and therefore a protective layer needs to be added, and the existing multimode optical fiber is lack of a waterproof function due to a single structure and has the problem that the connectivity after the multimode optical fiber is fixed with a router needs to be improved, so that the multimode optical fiber with reliable connection is provided.
