Filter-based WDM Device (FWDM)
T1550nm/R1310/1490nm
Wavelength Division Multiplexer
Description
The filter wavelength division multiplexer series are based on environmentally stable thin-film filter technology. The devices combine or separate light at different wavelengths in a wide wavelength range. They offer very low insertion loss, low polarization dependence, high isolation, and excellent environmental stability. These components have been extensively used in EDFAs, Raman amplifiers, fiber sensor systems, WDM networks, and fiber optics instrumentation.
