1. The use of composite materials instead of the conventional material PBT for manufacturing the microducts improves their strength and avoids fiber attenuation caused by the shrinkage of the ducts due to low temperatures. This feature makes them suitable for use in extremely cold regions.
2. The inclusion of reinforcement yarn between the microduct and outer sheath enhances the tensile strength of the fiber optic cable and can also be used as a pulling rope during cable installation.
3.The outer sheath is made of imported materials and modified to reduce the friction coefficient of the cable. It also features a microgrooved surface, which increases the contact area between the product and the air. These improvements effectively enhance the blowing distance of the product (patent protection has been applied for).
