How Mechanical Optical Switches Work
At their core, mechanical optical switches operate on a straightforward principle: physical movement of optical elements to control the path of light through fiber optic lines. This movement can be achieved through various mechanisms, each offering specific advantages for different applications.
When an activation signal is received, a precision-engineered actuator moves the optical components—typically fiber ends or reflective elements—into alignment, allowing light to pass through the desired path. When the switch needs to redirect the signal, the actuator moves the components to a new position, aligning with a different output port in the fiber optic lines network.
This physical movement ensures that the light signal experiences minimal distortion or loss when properly aligned, maintaining the integrity of data transmission through the fiber optic lines. The precision of these movements is extraordinary, often measured in micrometers to ensure optimal alignment and performance.
