1) This fiber type is single-mode G652, G655, or G657, or multi-mode, with a loose tube made of high-modulus plastic. A water-resistant filler compound is used for the filler.
2) The center used a steel wire positioned as a metallic strength member. For some cables, this steel wire is sometimes coated with polyethylene. The tubes (and filters) are twisted around the strength member into a compact, circular cable core. For PSP, the PE sheath is used.
3) by single or double cable for tie installation, also with PE for outer coating.
1. Reasonable design and precise control over the loose tube fiber in the remainder of a long optical fiber cable with excellent performance and tensile properties at temperature.
2. The high-strength, hydrolysis-resistant loose tube and special tube-filling compound ensure critical fiber protection. The specially designed compact structure effectively prevents the loose tubes from shrinking.
3. The specially designed compact structure is good for preventing loose tubes from collapsing.
4. Crush resistance and flexibility.
5. Long delivery length, small diameter, light weight and ease of installation
6. Excellent cable-side pressure shielding performance. And bulletproof capability.
Adopted for outdoor distribution fiber optic cable system.
Suitable for overhead conduit pipes, direct buried installation for anchoring method
Local and wide area network (LAN) communication system.
