The GYDTA optical cable structure involves inserting fiber ribbons into loose tubes made of high-modulus material, with the tubes filled with waterproof compound. The cable core centers on a metallic strength member, which for certain fiber counts is additionally coated with an extruded layer of polyethylene (PE). The loose tubes (and filler rods) are stranded around the central strength member to form a compact circular core, with interstices filled with water-blocking material. A longitudinally applied plastic-coated aluminum tape (APL) is sheathed before extruding a polyethylene (PE) jacket to complete the cable.

1. Excellent mechanical and temperature characteristics.
2. The loose tube material itself exhibits high hydrolysis resistance and superior strength.
3. Filled with specialized thixotropic gel, providing critical protection to the fibers.
4. The PE jacket offers excellent UV radiation resistance.
5. Utilizes LeFei Optoelectronic’s 4, 6, 8, and 12-core fiber ribbons for flexible application.
6. The following measures ensure the cable’s water resistance:
?· Single steel wire central strength member
?· Loose tubes filled with specialized waterproof compound
?· Complete cable core filling
?· Plastic-coated aluminum tape (APL) moisture barrier
?· Effective water-blocking materials prevent longitudinal water seepage
