12 Cores UG Underground Direct Burial Fiber Optic Cable GYFTY53
The Underground Direct Buried Fiber Optic Cable GYFTY53 are designed to provide high fiber counts with the flexibility and versatility required for today's most demanding installations, including direct buried. With fiber counts up to 288 and S-Z strand designs.
In the GYFTY53 cable, single-mode/multimode fibers are positioned in the loose tubes, the tubes are filled with water blocking filling compound.Tubes and fillers are stranded around the strength member into a circular cable core. Then the cable is completed with a PE sheath.Which is filled with the filling compound to protect it. After PSP is applied over the inner sheath, the cable is completed with a PE outer sheath.
Application:
1. Direct burial
2. Underground
3. Backbone Internet
Characteristics:
Excellent mechanical and temperature performance guaranteed by the accurate excess fiber length
Critical protection to fibers,
Excellent crush resistance and flexibility
The following measures are taken to ensure the water blocking performance of the cable:
- Single steel wire used as the central strength member
- Special water-blocking filling compound in the loose tube.
PSP moisture barrier
- 100% cable core filling and water-blocking material.
