Optical WDM Filter Wavelength Division Multiplexer 1x2 Broadband FWDM Module
1x2 Broadband FWDM Module Optical WDM Filter TX1550/RX 1310 & 1490nm ABS Box Packed
The 1310/1550nm Filter Wavelength Division Multiplexer is based on environmentally stable thin-film filter technology. The devices combine or separate light at different wavelength 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. These components have been extensively used in EDFAs, Raman amplifiers, WDM networks and fiber optical instruments.
