Polarization Maintaining Tap Isolator 1550nm, 1064nm
The Polarization Maintaining Tap Isolator combines a tap coupler and polarization sensitive isolator into a single compact package. It has high extinction ratio and very low insertion loss. The component is ideal for fiber amplifier and fiber optic system where signal monitoring is required.
GEZHI Photonics also produce compact size PM optical isolator, circulator, coupler/splitter, WDM, optical switch, combiner, PBS etc.
High power and Non-PM type are available.
