Isolator
Neptec’s optical fiber isolators permit light to transmit only in one direction. Neptec’s isolators are used to protect sensitive optical components from unwanted feedback and signals. Without isolators, sensitive and expensive equipment like optical cavities could easily be damaged by reflection signals.
Neptec offers a wide range of customization options including power handling, polarization-dependent and polarization-independent models for wavelengths ranging from 780 to 1550 nm. If the standard optical fiber isolator below does not fit your application, we would be glad to review your specifications and quote a custom isolator for you.
