Ultrahighdensity Fiber Optic Solutions Redefine Data Center Connectivity

Design doubles density without expanding cable diameter

The cable is engineered for high-density, space-constrained conduit environments, where traditional rigid cables can be difficult to store and deploy. By retaining the same outer diameter while increasing fiber count, the design seeks to expand transmission capacity in routes where adding new conduit is impractical.

Slotted core with FRP strength member

A nonmetallic fiber-reinforced plastic central strength member sits at the core of the slotted design. The structure allows flexibility in multiple directions, reduces cable weight by 10% to 15%, and is intended to make storage in manholes and ducts easier, according to the specifications.

12-fiber freeform ribbon

The 12-fiber freeform ribbon preserves the splicing performance of conventional ribbon cable while maintaining high-density packaging. Optimized crack-length ratios are used to improve ribbon flexibility and alignment accuracy in standard fusion splicer clamps, the specifications state.

Blowing tests point to longer installation distances

Air-blown installation tests show the slotted-core cable has roughly half the bending stiffness of a conventional central-tube cable, according to the design data. In a simulated route with multiple bends, the cable reached a blowing distance of 1,100 meters, about 1.3 times the distance of a non-slotted cable with the same outer diameter. That represents roughly 30% longer deployment in the tested route, reducing the complexity of long-distance installation, the data show.

The results are based on simulated conduit conditions and are intended to reflect common air-blown deployment methods. The design's lighter weight and directional flexibility are also expected to ease handling in manholes and other confined spaces.
