What industries use optical circulators
An optical circulator is a three- or four-port designed such that entering any port exits from the next. This means that if light enters port 1 it is emitted from port 2, but if some of the emitted light is reflected back to the circulator, it does not come out of port 1 but instead exits from port 3. This is analogous to the operation of an electronic. Fiber-optic circulators are used to separate optical signals.

Application Scenarios of Adjustable Attenuators
• Power Adjustment: Controlling optical power within the optimal operating range of receiving equipment (typically 1-30dB) to avoid overload or weak signals. Passive attenuators use resistor networks for signal reduction without power, while active attenuators can include components like MOSFETs and PIN diodes for adjustable attenuation levels. Attenuators can be classified according to different criteria. This section will analyze them from three perspectives: definition and function. What are the differences in the application scenarios of fixed fiber attenuators and adjustable fiber attenuators?- AnHui EAST Electronic Technology Co.
