WDM Product Series

Location:Home > WDM Product Series

Product Name:CWDM/DWDM Device

The wavelength division multiplexer series are designed and manufactured to Telcordial and ITU standard. The devices use environmentally stable thin film filters and advanced packaging technology to achieve wide pass band, low insertion loss, high channel isolation and excellent environmental stability. They can be used individually to perform single channel add or drop function or can be cascaded into sequence for multi-channel applications in CWDM/DWDM systems

Features

*  100G, 200G or CWDM channel number

*  Based on thin film filter technology and high wavelength stability

*  Low polarization dependent loss and high channel isolation

*  Flat and wide passband

*  Epoxy free optical path and excellent reliability  

*  Telcordia GR-1221-CORE qualified and RoHS compliant

Applications

* WDM system

* CATV system

* Telecommunication network system

* Single direction/Bi-direction transmission

* Line monitoring

* Metro/Access networks

* FTTX
