200GHz DWDM 1x2
Dense Wavelength Division Multiplexing (DWDM) utilizes thin film coating technology and proprietary design of non-flux metal bonding micro optics packaging to achieve optical add or drop at a ITU wavelength. It features 100GHz ITU Channel Spacing, low insertion loss, high channel isolation, wide pass band, low temperature sensitivity and epoxy free optical path.
It’s been widely used for wavelength add/drop in telecommunication network system, DWDM Network, PON network, Wavelength Routing, Fiber Optical Amplifier, CATV links.
