Do optical modules require precious metals
From energy-efficient LED lighting to advanced displays, a complex ecosystem of minerals including rare earth elements like lanthanum, cerium, terbium, europium, and transition metals such as indium and gallium enables unprecedented performance and energy efficiency. An optical module housing is the protective outer shell that encloses the internal components of an optical transceiver module. These modules are essential for converting electrical signals into light signals and vice versa, forming the backbone of fiber optic communication systems in data centers. Gallium arsenide (GaAs) prices have increased significantly since Q2 2026, driven by surging AI data center demand for optical modules and constrained gallium supply. GaAs's high electron mobility and direct bandgap make it crucial for optoelectronics and RF applications.
