This 1*2 Filter PM Fiber Standard Coupler is a high-performance polarization-maintaining (PM) fiber coupler based on Thin-Film Filter (TFF) technology. It is capable of splitting an input optical signal into two output ports according to a specified ratio while maintaining the stability of the optical signal's polarization state. Utilizing high-quality Corning Panda Fiber, this product features low insertion loss, a high extinction ratio, and excellent environmental stability, making it ideally suited for optical communication and photonic systems that demand high precision in power control and superior polarization-maintaining performance. With its compact structure and robust mechanical strength, this device can be widely integrated into fiber lasers, EDFAs, coherent communication systems, and fiber sensing platforms, serving as a critical passive component for achieving high-precision optical power distribution.
