HUA-NET 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 ITUwavelengths. 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 telecommunicationnetwork system.
Detailed description
Features ： Applications：
•Low Insertionloss •DWDM Network
•High ChannelIsolation •Wavlength Routing
•High Stability andreliability •Fiber Optical Amplifier
•Epoxy-free on OpticalPath •CATV fiberoptic System
