Rosendahl Nextrom raises the bar in loose tube production with its jelly dies

In the production of fiber optic cables for outdoor applications, loose tube manufacturing is a common method employed. It involves the creation of individual tubes, typically made of plastic, which serve as protective enclosures for optical fibers. These tubes provide flexibility and allow for the easy movement of fibers within the cable. During the production process, the optical fibers are placed within the loose tubes, which are then filled with a gel or water-blocking material to provide further protection against moisture and other environmental factors. 

The process of filling the loose tubes with gel involves using specialized equipment. Needle-like dispensing nozzles are often used in gel-filling machines to inject the gel into the tubes. It is at this point in the process that Rosendahl's ingenuity and research come into play, driving technological advancements that deliver promising innovations for the industry.

Rosendahl Nextrom’s new jelly die system brings significant benefits to the production of fiber optic cables. It improves jelly flow, process stability, and reduces variations in EFL (Excess Fiber Length). The optimized design minimizes turbulence, resulting in better quality and reliability. Compared to traditional needle systems, the compact jelly dies developed by Rosendahl Nextrom offer easier handling and require less maintenance.
