Technical Datasheet Note
For connectorized devices, IL increases by 0.3 dB, ER decreases by 2 dB, RL decreases by 5 dB and maximum guaranteed handling power is 1 W. High-power operation (>5 W) requires bare fiber or high-power collimated beam termination with adequate heat sinking.
Configuration and ordering notes

Configuration parameters include operating power level (0.3W, 10W, 20W, 30W, or 50W) and center wavelength (1030 nm for Yb-doped femtosecond lasers or 1064 nm for CW/MOPA fiber lasers). Engineering review covers fiber type (e.g. PM980, PM 10/125, or custom LMA fiber) to match the laser optical path.

Selection Guidance: Review thermal dissipation, damage thresholds and cooling options in our High Power Optical Isolator Guide ↗ or compare operating bands in the 1064nm and 1550nm Optical Isolator Selection.

Key Applications

High-power MOPA fiber laser systems; Industrial ultrafast fiber lasers; Pulsed fiber amplifiers; Laser marking and precision micromachining.
