1310/1550nm SM Single-Stage Twin Optical Isolator

Enquire Now

The OITS Series 1310/1550 Twin Single Stage Optical Isolator integrates two independent isolators into one standard isolator package. Each isolator guides light at 1310/1550 nm in the normal direction while 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, extremely high isolation, compact structure, and high stability. These Telcordia qualified components have excellent characteristics, making them an ideal choice for application in fiber amplifier systems, pump laser diodes, and optical fiber sensors.
