Description
The structure of the GYFTY53 optical cable is to insert 250µm optical fibers into loose tubes made of high modulus materials, and fill the loose tubes with waterproof compounds. The center of the cable core is a non-metallic reinforcing core (FRP). For some optical cables with a certain number of cores, a layer of polyethylene (PE) needs to be extruded on the outside of the non-metallic reinforcing core. Loose tubes (and filling ropes) are twisted around the central reinforcing core to form a compact and circular cable core, and the gaps inside the cable core are filled with water-blocking fillers. A layer of polyethylene inner sheath is extruded on the outside of the cable core, and the double-sided plastic-coated steel tape (PSP) is longitudinally wrapped and then extruded into the polyethylene sheath to form the cable.
Feature
● It has excellent mechanical properties and temperature characteristics
● The loose sleeve material itself has good hydrolysis resistance and relatively high strength
● The pipe is filled with special grease, providing critical protection for the optical fiber
● Good compressive strength and flexibility
● The following measures are adopted to ensure the waterproof performance of the optical cable:
- A single non-metallic central reinforcing core
- The loose sleeve is filled with special waterproof compound
- Complete core filling
- Double-sided plastic-coated steel tape (PSP) enhances the moisture resistance of optical cables
- Good water-blocking materials prevent longitudinal water seepage in optical cables
