  • The LiNbO₃ Series High-Speed Modulator Product Line of AFR in Italy is Fully Resumed to Work
    May 08, 2020 The LiNbO₃ Series High-Speed Modulator Product Line of AFR in Italy is Fully Resumed to Work

    May 4, 2020 --- The wholly owned subsidiary of Advanced Fiber Resources in Italy Milan AFR (AFRML) is fully resumed to work after several months of suspension. As the spread of the epidemic is gradually slowing down in Italy, AFRML is planning to restart production with strict epidemic control.

    To prevent the spread of COVID-19, AFRML has set up a special committee based on the recommendation of official guidelines. The goal of the committee is to strictly monitor the health safety during the restart process and to fulfill the requirement of any relevant parties. The company strictly complies with the epidemic prevention regulation created by the local government and will take every possible measurement to ensure employees health safety as well as public sanitation.

    AFRML owns a LiNbO₃ series high-speed modulator and analog modulator product line located in San Donato, Italy. The product line, which started at Pirelli Research Laboratory near Milan, has a strong technical and production team and has been dedicated to the research and development of the most advanced optical modulator products, with broad market opportunities in communications and sensing industry. Lithium niobate modulator is widely used in modern optical communication system and is the core component to realize electro-optical conversion. With the introduction of "new infrastructure" 5G infrastructure, the demand for such products is increasing.

    With fully resumption of production, the company will restore normal capacity of the lithium niobate modulator product line, solving the current supply shortage. In the future, AFRML will also expand the production scale and enrich the product line by utilizing its competitive advantages of technology development, quality control, market development and other aspects.
