An optical isolator is a passive device that allows light to pass in one direction and prevents light from passing in the opposite direction. Its function is to limit the direction of light, so that light can only be transmitted in single direction. The light reflected through optical fiber echo can be well isolated by the optical isolator, improving the transmission efficiency of light wave.
Features of Optical Isolators
- High isolation
- High return loss
- High reliability
- High stability
- Low insertion loss
- Low Polarization Dependent Loss
- Low Polarization Mode Dispersion
