Microduct fibre cable (PA)
1.Features and Benefits
A. Optimum cable structure, high fibre density
B. Accurate fibre length balance, ensure stable performance
C. No gel in cable core for water blocking, low carbon and environmental
D. Structure Innovation in sheath, enhancing the blowing performance
