Technical Field

The invention relates to the technical field of optical cable butt joint, in particular to an optical cable fusion butt joint device and an optical cable fusion butt joint method.

Background

Optical fibers, also known as optical fibers, are a type of fiber made of glass or plastic and use the principle of total internal reflection of light transmitted in these fibers as a light-conducting means. The tiny optical fiber is encapsulated in a plastic sheath so that it can bend without breaking. Typically a transmitting device at one end of the optical fibre uses a light emitting diode or a laser to send pulses of light into the fibre and a receiving device at the other end of the fibre uses a photosensitive assembly to detect the pulses.

The optical fiber fusion splicer is mainly used in optical communication, construction and maintenance of optical cables. The method mainly comprises the steps of melting two optical fibers by discharging an electric arc, and simultaneously adopting a collimation principle to gently push so as to realize the coupling of optical fiber mode fields. When the optical cable is broken accidentally or needs to be connected in an extending mode, the existing optical fiber fusion splicer needs to perform core pulling and coating removal treatment on fiber cores at joint positions respectively during use, and the fiber core fusion splicing efficiency is low.
