AI Overview
20 W low power fiber isolators are specialized passive components designed to handle average optical powers up to 20W, commonly used in fiber lasers, amplifiers, and optical sensing applications to prevent feedback. These devices feature low insertion loss and high isolation (typically >25-30 dB), and are often available in polarization-maintaining (PM) or polarization-insensitive configurations.
Key Specifications for 20W Fiber Isolators
- Average Power Handling: Up to 20W CW (Continuous Wave).
- Wavelength Options: Commonly available for 780 nm, 850 nm, 980 nm, 1030 nm, 1064 nm, and 1550 nm, according to wdmquest.com, Agiltron, and Fiber Resources.
- Isolation: Typically 25 dB to 35 dB (peak).
- Insertion Loss: Often 0.5 dB to 1 dB.
- Fiber Type: Polarization Maintaining (PM) or Single-Mode (SM), often using HI1060 or PM1550 fiber, as noted by Fiber Resources and TaorLab.
- Peak Power: Up to 10 kW (for 10 ns pulses).
