On 1 April 2025 the Netherlands will modify its national export control measure for advanced semiconductor manufacturing equipment. For. Rules for the export of chip production equipment will once again be tightened, the Minister of Foreign Trade, Reinette Klever, has said. She added that this only concerns “a very limited amount of technology and goods. What began as a purported “corporate governance” measure quickly unraveled as a geopolitically motivated move, intertwined with U. In a significant move underscoring growing geopolitical tensions surrounding critical technology, the Dutch government has stepped in to restrict the influence of Chinese-owned semiconductor company Nexperia. These controls will enter into force on 1 December 2024 and will be implemented through the Dutch Regulations Supplemental Controls to the Dual-Use.

While traditional fiber optic cables contain individual fibers encased in a protective jacket, ribbon fiber cables organize fiber optic strands in a flat ribbon structure, creating freedom with space conservation and cable management. Ribbon cables offer higher fiber counts and greater fiber density than any other cable construction designed for the outside plant (OSP), four times the highest-fiber-count loose tube cable. Unlike traditional loose-tube or tight-buffered cables, ribbon cables bundle multiple fibers together in parallel alignment. ”), some people call it a bundled fiber.
