The PU516A 3BSE032402R1 is an optical isolator 1. Optical isolators, also known as optical insulators, photocouplers, etc., are mainly used in the laser industry, and the coherence of light will not be affected.
The optical isolator is to avoid the reverse reflection of the transmission signal. In the process of light transmission, when the light is allowed to pass through the optical fiber, it may be reflected back. In order to avoid the reverse reflection of the transmission signal, the optical isolator 1 is used.
