980/1550 nm Singlemode WDM

The Singlemode Wavelength Division Multiplexer combine or separate light at different wavelengths. They offer very low insertion loss, low polarization dependent loss, high isolation and excellent environmental stability. These components have been extensively used in EDFA, CATV, WDM networks and fiber optic instruments.
