The Polarization Insensitive Tap Isolator combines a tap coupler and polarization insensitive isolator into a single compact package. It has low polarization dependent loss and very low insertion loss variation. This optical isolator is ideally suited for fiber amplifiers and fiberoptic systems where signal monitoring is required.
