Description:
Filter WDM1. High Isolation
2. Low Insertion Loss
3. Low Polarization
4. RoHs Compliant
2000/1570 nm Filter Wavelength DivisionMultiplexer
The Filter Wavelength Division Multiplexer isbased on environmentally stable thin-film filter technology. Thedevices combine or separate light at different wavelength in a widewavelength range. They offer very low IL, low polarizationdependence, high isolation and excellent environmentalstability.
