Flyin Optronics’ 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	Applications
Low Insertion Loss	Channel Add/Drop
Wide pass band	DWDM Network
High channel	Wavelength Routing
High stability and reliability	Fiber Optical Amplifier
Epoxy free on optical path	CATV Fiberoptic System
