1310/1550 & 1480/1550nm Singlemode WDM
⠀⠀⠀⠀⠀⠀⠀⠀⠀
extensively used in EDFA, CATV, WDM networks and fiber optics instrumentation
The Singlemode Wavelength Division Multiplexers combine or separate light at different wavelengths. They offer very low insertion loss, low polarization dependence, high isolation and excellent enviromental stability. These components have been extensively used in EDFA, CATV, WDM networks and fiber optics instrumentation.
