Title: Innovations of Takashi Tanaka in Optical Fiber Technology
Introduction
Takashi Tanaka, an innovative inventor based in Kamakura, Japan, has made significant contributions to the field of optical fiber technology. With a total of two patents to his name, Tanaka is recognized for his expertise and creative solutions in fiber optic communications.
Latest Patents
One of Tanaka's notable innovations is the **S-Z stranded optical cable with optimized short ROL pitch**. This invention features a loose tube fiber optic cable that contains a core made of S-Z stranded strands. These strands comprise optical fibers organized in first and second sections that alternate throughout the length of the cable. The optimized reduction in the distance between ROL transition points enhances access during mid-span entry, ensuring that transition points are located within the sheath entry window when accessing the cable.
Another significant patent is the **water-blocked optical fiber communications cable**. This design eliminates the need for viscous water-blocking compounds outside the buffer tubes. Instead, it employs water-swellable yarns wrapped around the central strength member and a water-swellable tape situated between the core and the jacket of the cable. This innovative approach allows the cable to effectively absorb water, thereby protecting its integrity.
