Filter Wavelength Division Multiplexer
The Filter Wavelength Division Multiplexer is extensively used in EDFA, Raman amplifiers, WDM networks and fiber optics instrumentation. The FWDM series is based on environmentally stable Thin Film Filters technology. The device combines or separates light at different wavelengths in a wide wavelength range. They offer very low insertion loss, low polarization dependence, high isolation and excellent environmental stability. High power handling capability can be achieved through unique pigtail processing and high quality AR coating.
C Band/L Band Wavelength Division Multiplexer
The C Band/L band filter wavelength division multiplexer is a micro optics device based on environmentally stable Thin Film Filters technology. It is used to combine or separate C band wavelength signals and L band wavelength signals in DWDM systems. The components are characterized with wide pass band, low insertion loss, high return loss, excellent environmental stability and high power handling capability.

Q. Can you supply a wavelength splitter or Y cable to split 1310nm and 150nm?
A. Yes, we can supply a Y cable which is the same as a filter type WDM which can split or combine 1310nm (1270~1350nm) and 1480/1550nm (1480~1600nm). The WDM splitter is a bi-directional device that can be supplied with SC, LC or FC connector types on any port.
