Description

End protection assembly of optical fiber cable Technical Field The utility model relates to the technical field of end protection of optical fiber cables, in particular to an end protection assembly of an optical fiber cable. Background The definition of optical fiber cable can be divided into two parts, namely optical fiber and optical cable, wherein the optical fiber and optical cable are combined to form a core transmission medium for modern communication, the optical fiber is a fibrous material made of glass or plastic, optical signals (optical pulses) are transmitted by the principle of total reflection, and the optical cable is a composite cable formed by adding a protective layer (such as a metal or plastic sheath) to a plurality of optical fibers (usually containing a plurality of optical fiber bundles), a reinforcing member (such as steel wires or fibers) and a filler. An end protection assembly of an optical fiber cable refers to a device or structure for protecting an optical fiber or cable end (e.g., fiber optic splice, cable exit, etc.) from physical damage, environmental attack, or signal interference, which is typically installed at the exposed end of the optical fiber or cable, ensuring reliability and long-term stability of the optical fiber connection. The end protection assembly of the existing optical fiber cable generally sleeves the optical fiber cable into the end protection assembly through a metal sleeve (such as stainless steel and aluminum alloy) so as to achieve the protection effect, but when the metal sleeve is used, the metal sleeve is generally only provided with physical wrapping, and the inside of the end protection assembly is generally free of a stabilizing mechanism such as a clamp, a glue or a clamping groove, and the optical fiber cable can slightly displace due to vibration, bending or temperature change, so that signal fluctuation is caused.
