Strengths of II-VI

Vertical integration strategy

With a vertical integration strategy that cannot be imitated by other optical transceiver vendors, we consistently use our own technology and equipment from the main parts that make up the optical transceiver (IC, light emitting element, light receiving element), their packaging, final assembly to testing. By adopting it, we will provide products with cutting-edge technology with stable quality and supply system. We have set up the world's largest mass production factories in Malaysia and China, and will respond to the growing demand for optical transceivers accompanying the rapidly expanding traffic.
