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.
Characteristics
· Good mechanical and temperature performance
· High strength looes tube that is hydrolysis resistant
· Special tube filling compound ensure a critical protection of
fiber
· Crush resistance and flexibility
· The following measures are taken to ensure the cable watertight:
- Steel wire used as the central strength member
- Loose tube filling compound
- 100% cable core filling- APL moisture barrier
- PSP enhancing moisture-proof Water-blocking materialStandard
GYTY53 cable complies with Standard YD/T 901-2001as well as IEC
60794
