Fiber Color Identification
Individual fibers and loose tubes follow TIA/EIA-598-A standard color coding:
- Steel tube 1 (Fibers 1-12): Standard color sequence
- Steel tube 2 (Fibers 13-24): Black tracer (50mm pitch)
- Steel tube 3 (Fibers 25-36): Black tracer (100mm pitch)
- Steel tube 4 (Fibers 37-48): Black tracer (150mm pitch)
Packaging & Shipping
OPGW is tightly and uniformly wound on strong wood-iron reels conforming to ANSI/AA 53-1981 standards, protected by battens to prevent damage during shipping, handling, storage, and stringing operations.
