An optical sub-assembly (OSA) is a compact assembly of optical components designed to perform specific functions in optical systems, typically used in telecommunications and data communication applications. It usually includes elements such as lenses, filters, and fibers, all integrated into a single module to facilitate efficient light transmission and signal processing. OSAs help simplify the design and manufacturing of optical devices, improve performance, and reduce overall system size. They are crucial in applications like fiber optic transceivers and laser systems.
