The fiber optic cable manufacturing technology has achieved great progress along with the rapid development of China’s optical communication industry.But with the increasing competition from the market

many cable manufacturers have researched and developed new products.They have optimized and upgraded the product structure and strengthened the selection of raw materials to ensure the product competitiveness of their enterprises.Based on the case of GYXTW 12B1.3

this article briefly describes the production method of a new-type central loose tube optical cable

certifying the reasonableness of the new cable structure from the point of production practice and theoretical design.The new structure is discussed mainly from the optimization of phosphating steel wire.
