loose tube fiber

The compact core is a constructive design of optical fibers. In this optical waveguide, the secondary coating is not firmly attached to the fiber, but loosely encases the optical waveguide.

The cladding may consist of one or more plastic layers with a gel between them, similar to the hollow core but with smaller gaps.

Structure of the compact core

Structure of the compact core

The radial fiber clearance is only a few hundredths of a millimeter. The outer diameter of the compact core is identical to that of the solid core. The advantages of the compact core over the solid core are its better strippability and its minimal influence due to micro-bending and temperature effects.
