Three-port optical circulator
A three-port optical circulator is an optical device designed so that light entering any port exits from the next port. Working principle: 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 exit from port 1, but instead exits from port 3. Fiber optic circulators are used to separate optical signals traveling in opposite directions in an optical fiber, for example to achieve bidirectional transmission on a single fiber. Due to their high isolation of input optical power and reflected optical power and their low insertion loss, optical circulators are widely used in advanced communication systems and fiber optic sensor applications.

Against the evolving demands for military‑grade hardware, rail transit equipment and heavy‑duty machinery that run under high‑shock vibrating conditions, anti‑loose connectors serve as indispensable hardware for stable power delivery and high‑speed signal transmission.
For low-frequency RF, electromagnetic testing and power combining systems, conventional resistive power dividers bring high insertion loss, while standard directional couplers cannot provide equal-amplitude signals with 180° phase shift. They fail differential circuits, balanced amplifiers and signal cancellation systems.
For pulsed laser and full-spectrum optical testing, photodiodes and thermopiles have inherent drawbacks. Photodiodes show weak response in infrared band, while thermopiles feature slow response and cannot capture nanosecond narrow pulses.
