1030nm Polarization Maintaining Optical Isolator

1030nm Polarization Maintaining Optical Isolator

The 1030nm Polarization Maintaining Optical Isolator is a passive fiber optic component designed to transmit light in one direction while suppressing backward reflections and maintaining the polarization state of the optical signal. Optimized for 1030 ±5 nm operation, it features ≥28 dB isolation, ≥32 dB peak isolation, ≤3.5 dB insertion loss, ≥50 dB return loss, and ≥18 dB extinction ratio. The isolator uses PM980 polarization maintaining fiber and supports slow-axis operation by default, with fast-axis and both-axis configurations also available. Its compact Φ5.5 × 35 mm package is suitable for integration into fiber lasers, optical amplifiers, fiber sensing systems, and other polarization-sensitive optical applications requiring stable polarization control and protection from back reflections.
