1×2 1310~1550nm Polarization Beam Combiner (PBC), PM Fiber Beam Combiner

A Polarization Maintaining (PM) Beam Combiner is an optical device used to combine light beams from multiple input fibers into a single output fiber while maintaining the polarization state of each input beam. This device is widely used in optical communication systems, lasers, and optical sensors, especially in applications requiring high precision and stability. PM Beam Combiners are characterized by polarization maintenance, high power handling, low insertion loss, and high isolation, effectively reducing signal loss and enhancing system performance. They are commonly used in fiber lasers to combine beams from multiple laser sources for higher output power, in optical communication systems to merge multiple signals into a single fiber for transmission, and in high-precision optical sensors to improve detection accuracy.
