1260~1620 nm CWDM Coarse wavelength Division Multiplexer 900 um
fiber high channel isolation access networks A 3 port CWDM Datasheet.docx
Coarse Wavelength Division Multiplexer (CWDM) devices demonstrate
low loss and reliable performances.
These devices show broad passband and high isolation, making them
ideal for operation with inexpensive, uncooled lasers. They are low
cost products for the CATV and metro/access markets.
Easily customizable, CWDMs can be configured from a standard list
of packaging and connector options.
Features
- Low insertion loss
- High channel isolation
- Low polarization dependent loss
- Exceptional reliability and stability
Application
- Access networks
- Metro WDM Systems
- Enterprise networks
