Operating Principle

1）Serious flaws of traditional fiber protection sleeve Current fiber protection sleeve was invented by Japanese researchers 44 years ago in 1981. There are major flaws in the current fiber protection sleeve. (a) Because the optical fiber does not have its own dedicated space, the hot-melt glue tube flows uncontrollably after melting, causing the optical fiber to bend slightly, resulting in significant additional loss and even fiber breakage. (b) The ceramic semi-cylinder is a poor thermal conductor which results in uneven melting of the hot melt glue during the curing process. 

2）Protection principle of perforated tube fiber protection sleeve Strength member of the new fiber protection sleeve is a perforated metal tube with numerous through holes formed using a sheet metal process, which has a low production cost and good thermal conductivity. When in use, the optical fiber ribbon is inserted into the perforated tube, and then heat curing commences. The plastic of the hot-melt glue tube melts into liquid, which is squeezed through the through holes of the perforated tube by the heat-shrinkable tube and reconstitutes inside the perforated tube. The cooled plastic surrounds all optical fibers securely to achieve the protection effect. The optical fibers are protected by an optical fiber “protection cage" in 360° directions and has high symmetry
