Polarization Insensitive Tap Isolator

产品详细信息

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.
