Description
3 Ports CWDM Device, Filter Channel Centers ITU or ITU+1
Arkoptics’ Coarse Wavelength Division Multiplexer (CWDM) Devices are compact and lightweight passive components based on thin film filter micro-optics to achieve wide passband, low insertion loss, and high channel isolation. The filters are designed to provide high-quality signal transmission over long distances and are ideal for operation with inexpensive, uncooled lasers. CWDM filter devices are widely used in Access Networks and Metro WDM Systems. All our products meet the GR-1209 and GR-1221-Core standards. They are rigorously tested and come with our limited lifetime warranty.
–High Channel Isolation
–Low Insertion Loss
–High Stability and Reliability
–Low Polarization Dependent Loss
–Epoxy-free Optical Path
