Normally, micro-duct cables are jetted into an appropriately sized micro-duct. To insure that the jetting operation can be done efficiently, micro-duct should be selected to have some space between its inner diameter (ID) and the cable it contains. The recommended fill ratio has been empirically det

Silicon Duct and Micro Duct, as the world's most advanced optical cable sheathing materials, have been widely used in communication optical cable sheathing in various fields. They not only protect optical cables, but also speed up the construction of optical cables. , which can save the investment a
