Technical Field

[0001] The utility model relates to the technical field of stranded optical cable processing, in particular to a stranded optical cable water-blocking grease filling device. Background Technique

[0002] The stranded optical cable is a common optical cable structure, which is composed of multiple sheathed optical fibers twisted around a strengthening core. This structure is similar to the traditional cable structure, so it is also called a classical optical cable. The central part of the stranded optical cable is usually a metal or non-metal strengthening member, and the optical fibers are wound around the periphery of this strengthening member to form a layered shape. This structure helps to control the slack length of the optical fibers and adjust the twist pitch, realizing a more uniform, stable and reliable distribution of the slack length of the optical fibers. Usually, water-blocking grease is filled inside the stranded optical cable to improve the waterproof ability of the optical cable.
