Two stainless steel wires are inserted into the spiral valley of the standard Square-Locked tube, for achiving a greater bending radius. The double stainless steel wires provide a guaranteed minimum bend radius and superior stability to the tube.
By changing the rod and wire size, any desired bending radius can be made. The SLDS Bend-Limiting Tube can be made ultra-light and strong by adding a rod of titanium.

Applications
Features
Protection for the large bending radius optical fibers, such as quartz type and hollow fibers
The SIDS or Semi-Interlock type features two stainless steel wires inserted into the spiral valley of the tube. This results in a larger minimum bend radius and superior stability, which makes the SIDS type bend-limiting tube an ideal solution for optical fibers, especially for laser fibers, quartz-type optical fibers, and hollow optical fibers.
