Loose Tube Layer Stranded All-dry Optical Cable（DCFA）

Colored optical fibers are placed into a loose tube made of high-modulus, hydrolysis-resistant material, which is filled with thixotropic water-blocking gel. The core of the cable consists of a non-metallic strength member(FRP), around which the loose tube(and filling rope)is twisted to form a compact and circular cable core. Both the loose tube and the strength member are wrapped with water-blocking yarn. Longitudinally wrapped water-blocking tape is applied to the cable core, followed by longitudinal wrapping with coated aluminum tape and extrusion of a polyethylene sheath to form the cable.

DETAILS

◆ Exhibits good mechanical performance and temperature characteristics.

◆ The material of the loose tube has good hydrolysis resistance and excellent pressure resistance.

◆ Special water-blocking yarn is placed inside the loose tube to provide crucial protection for the optical fibers.

◆ The tight cable structure effectively prevents tube shrinkage.

◆ Features a moisture-resistant layer of coated aluminum tape.

◆ The polyethylene sheath has excellent resistance to ultraviolet radiation.

Note:

a.The suffix Xn in the model indicates the selected fiber type, see Yangtze Fiber Model Explanation for details.

b.The color arrangement of the loose tube and fibers can be found in the chromatogram.

c.The minimum thickness of the polyethylene sheath is 1.5mm.

d.The cable should not be stored in open-air environments for more than 6 months, otherwise the spool may be damaged.
