TFF Module
- Low insertion loss
- Wide pass band
- High channel
- High stability and reliability
- Epoxy free on optical path
Abalone 100GHz/200 GHz 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.
Features and Benefits:
- Low insertion loss
- Wide pass band
- High channel
- High stability and reliability
- Epoxy free on optical path
