Loose Tube Technology

Loose
tube technology is to put the once-coated colored optical fiber in a PBT
sheathed plastic tube. The optical fiber is usually placed in the middle
according to the designed extra length. The loose tube is filled with
thixotropic ointment to prevent water infiltration. The excess length of the
loose tube is stable, non-hydrolyzable, soft and easy to construct.

Optical Cable Structure

The double-sided
plastic-coated corrugated steel strip with a thickness of 0.2mm is
longitudinally wrapped outside the central tube strap, and the interface
overlaps. This structure has excellent moisture resistance.
