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. The component is
ideally suited for fiber amplifier and fiberoptic system where signal monitoring is required.
