1310/1550nm High-Power PM Single-Stage Optical Isolator


1310/1550 high power polarization maintaining single stage optical isolator is a passive device that maintaining polarization while guiding light at 1310/1550 nm in the normal direction, and minimizing back reflection and back scattering in the reverse direction for any state of polarization. Employing Agiltron’s proven advanced micro optics design, it features low insertion loss, high power handling, extremely high isolation, high extinction ratio, compact package and high stability.  making them an ideal choice for application in fiber amplifier systems, optical fiber sensors and instrumentation.
