Specifications

Flyin Optronics' 200GHz dense wavelength division multiplexer (DWDM module) utilizes thin film coating technology and proprietary design of non-flux metal bonding 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 epoxy free optical path . It can be used for wavelength add/drop in telecommunication network system. Featuresl    Low Insertion Lossl    Wide pass bandl    High Channel Isolationl    High Stability and reliabilityl    Epoxy-free on Optical Path Applicationsl    Channel Add/Dropl    DWDM Networkl    Wavlength Routingl    Fiber Optical Amplifierl    CATV fiberoptic System Performance Specifications
