Optico Dense wavelength division multiplexer (DWDM)utilizes thin film coating technology and proprietary design of non-flux metalbonding micro optics packaging to achieve optical add and drop at the ITU wavelengths. It provides ITU channel center wavelength, low insertion loss,high channel isolation, wide pass band, low temperature sensitivity and epoxyfree optical path . It can be used for wavelength add/drop in telecommunication network system.Standard DWDM Mux/Demux package type include: ABS box package, LGX pakcage and 19” 1U rackmount.
