Direct burial fiber cable (GYTA53)
Product standard: YD/T 901-2018
Suitable for: direct burial
Precisely controlled residual length of optical fiber ensures good tensile performance and temperature characteristics.
The loose tube material itself has good hydrolysis resistance and high strength. The tube is filled with special oil paste, which provides key protection for the optical fiber.
Good lateral compression resistance and flexibility;
Adopt the following measures to ensure the cable waterproof performance:
- Single steel wire center reinforcement core;
- The loose tube is filled with special waterproof compound;
- Full cable core filling;
- Double chrome-plated plastic steel belt (PSP) improves cable moisture resistance;
- Coated with plastic-aluminium strip (APL) moisture barrier;
- Good water-blocking material to prevent longitudinal water seepage of optical cable.的阻水材料防止光缆纵向渗水。
