The optical fiber serial number and corresponding color meet the requirements in the table below, and those with less than 12 colors are selected according to the serial number.

Fiber Identification Chromatography

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.
