"Prysmian has unveiled a new single-mode fiber optic cable with a coating diameter of 160 microns. According to the company, this is the first bend-tolerant fiber of this size to become commercially available. The development is aimed at further miniaturization of fiber optic cables, so that more fibers can be accommodated in the same physical space. The smaller diameter allows cables with a higher fiber density to be designed."
"The new fiber is based on Prysmian's BendBrightXS technology. According to the R&D team, this technology makes it possible to significantly reduce the dimensions of cables while maintaining their bending performance. This gives cable designers more freedom to create compact designs with a higher fiber concentration than was previously possible. Despite the thinner coating, the glass diameter remains 125 microns, the same as that of conventional single-mode fibers. The cross-sectional area of the fiber is therefore more than half that of the standard 250-micron variant."
Prysmian introduced a bend-tolerant single-mode fiber with a 160-micron coating diameter to enable higher fiber counts in constrained spaces. The reduced coating diameter supports cable designs with greater fiber density for underground conduits, buildings, and data centers. BendBrightXS technology allows significant cable dimension reduction while preserving bending performance, enabling more compact cable architectures with increased fiber concentration. The glass core remains 125 microns, matching conventional single-mode fibers, and the cross-sectional area is more than half smaller than the standard 250-micron variant. The fiber complies with ITU-T G.652 and G.657.A2 and uses ColorLockXS for mechanical protection and bend insensitivity, supporting network densification and efficient infrastructure use.
