Description

  The present invention relates to the technical field of a sheath tube optical fiber, and more particularly to a sheath tube optical fiber having a connection plug.

  Since the optical fiber cable cannot have a large refraction angle, it is not as strong as a general copper cable. Therefore, the sheath tube optical fiber cable is applied to the current optical fiber structure.

  Known sheath tube optical fiber technology uses a metal sheath tube to directly cover the outside of the bare optical fiber to protect the bare optical fiber and avoid damage due to inappropriate refraction. However, the sheath tube has a hard material characteristic and may be provided outside the sheath tube. According to other known sheath tube optical fiber technology, the bare optical fiber cannot be connected to another optical fiber or optical fiber plug without performing an optical fiber welding process after the cutting operation. Thus, this type of structure must be spliced to another optical fiber or connector using an optical fiber welder, which greatly reduces the convenience of use.

From the above description, it can be seen that the sheath tube optical fiber with known connection plugs still has drawbacks and is deficient. Therefore, as a result of repeated researches by the inventor, a sheath tube optical fiber having the connection plug of the present invention was devised.
