3 port 1480/1550nm FWDM Multiplexers Component
1480/1550nm FWDM - for high-power DWDM optical amplifier and EDFA
1480/1550 nm FWDW is based on thin-film filter technology and metal bonding micro-optic packaging. This component is used to combine or separate 1480 and 1550nm band signal. 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.
