1030nm Single Mode Polarization Insensitive Optical Isolator

1030nm Single Mode Polarization Insensitive Optical Isolator

The 1030nm Single Mode Polarization Insensitive Optical Isolator is a passive fiber optic component designed to transmit light in the forward direction while suppressing backward reflections, helping protect optical sources and maintain stable system performance regardless of the input polarization state. Optimized for operation at 1030 ±5 nm, it features low insertion loss of ≤3.5 dB, isolation of ≥23 dB, peak isolation of ≥26 dB, return loss of ≥50 dB, and polarization dependent loss of ≤0.1 dB. The isolator uses Hi1060 fiber and a compact Φ5.5 × 35 mm package, making it suitable for integration into fiber laser, fiber amplifier, fiber sensing, and optical communication systems. FIRSOL also provides customization options for wavelength, fiber configuration, pigtail length, and connector type to meet different system requirements.
