GYFXTY all-dielectric outdoor cables use central loose tube structure, which are filled with water-resistant filling compound to provide crucial protection for the fiber. Over the tube, water-blocking material is applied to keep the cable watertight. Two parallel fiber reinforced plastics (FRP) are placed at the two sides, which has an excellent anti-electromagnet ability and lightning resistance performance. The cable is completed with a single polyethylene (PE) sheath. It is especially suitable for installation in aerial for long-distance and bureau communication and wiring in multiple minefields and electromagnetic interfering places.

Cable is supplied in lengths as specified in PI or as requirement. Each length will be shipped on a separate iron-wooden drum. The minimum barrel diameter of the drum will not be less than 30 times the cable diameter.
The cable ends will be sealed with plastic protection caps to prevent water penetration. The ends will be easily accessible for testing. A final inspection test report with attenuation performance data for each fiber is attached inside the drum.
