DWDM Add-Drop filter (OADM)
DWDM Add-Drop filter for combining / separating optical signals with different wavelengths in sealing systems.
Dense wavelength division multiplexer (DWDM) 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 .

- Wide pass band
- High Channel Isolation
- High Stability and reliability
- Epoxy-free on Optical Path
Application
- Line Monitoring
- WDM Network
- Telecommunication
- Cellular Application
- Fiber Optical amplifier
- Acess Network
