GYFTA (non-metallic strengthening member, loose tube stranded filling type, aluminum-polyethylene bonded sheathed outdoor optical fiber cable for communication) The structure of the optical cable is to sheath single-mode or multi-mode optical fiber into a high-modulus plastic Fill the loose tube with waterproof compound. The center of the cable core is a non-metallic reinforced core (FRP). For certain fiber optic cables, a layer of polyethylene (PE) is extruded outside the non-metallic reinforced core or a non-metallic reinforced yarn is added to the cable core. line. The loose tube (and filling rope) is twisted around the central reinforcing core to form a compact and circular cable core. The gaps in the cable core are filled with water-blocking compounds, and the plastic coated aluminum tape is longitudinally wrapped with a polyethylene sheath.

Technical Data Sheet
Environmental performance of optical cable
| Pilot projects | experiment method |
| Temperature cycle test | a. Temperature steps: +20 ℃ , -40 ℃ , +70 ℃ , +20 ℃ ;
b. Holding time: 12 hours per step for single-sheathed optical cable , 24 hours per step for double-sheathed optical cable , number of cycles: 2 cycles; |
| Water seepage test | The water permeability of the finished optical cable should meet the requirements of IEC60794-1-F5B , and it should be carried out on the full section of the optical cable, meeting the requirements of 1m water column, 1m optical cable, and no water seepage for 8 hours. |
| Optical cable outer sheath
Insulation resistance |
An outer cable sheath insulation resistance ( armor layer between the inner and the outer sheath of the earth ) , soaking in the cable 24 hours after the test, of not less than 2000 M • km (DC 500 V test). |
| Dielectric strength | Between the inner armor layer of the outer sheath and the earth: test after the optical cable is immersed in water for 24 hours, not less than DC 15 kV for 2 minutes. For double-sheathed optical cables, it is required that between the outer sheath and the inner armor and the metal reinforced core: no less than DC 20 kV for 5 seconds, in line with the requirements of GB/T 1408.1-2006 . |
| Drip test | Under the environmental conditions of 70 ℃ ( 24h ), the optical cable should not drip out of filling compound and coating compound. |
