COD is the abbreviation of the English Corrugated Optic Duct corrugated fiber optic catheter. This is on the basis of summed up the past, a variety of fiber optic cable, cable ducts of the pros and cons of a new concept developed by a new generation of high performance fiber optic catheter. It uses a very low coefficient of friction modified HDPE as the main raw material, the edge wall pipe structure with very low friction coefficient for the tubes to high voltage, easy to bend the bellows to the mother pipe, made by the composite extrusion. High pressure, flexible, differentiated, easy construction of the main features of many other products can not match advantage in terms of physical performance, service life, construction 

 Qingdao Jia Sen Plastic Machinery COD fiber optic cable pipe production line is developed its own, and the first at home and abroad to introduce new products (Plum), high yield, simple process, high degree of automation, easy to operate features, fill the blank of domestic and foreign at the international leading level.
