400G nWDM Filter Block
Auxora’s Narrow-band WDM Filter Block (nWDM Filter Block)
is a broad portfolio of vertically-integrated products using precision optical thin film filters and micro-optic structure. It is designed and manufactured in house with our proprietary processes including optical thin film coating, precision dicing and polishing, micro-optic assembly, and high-volume automatic assembly manufacturing. This nWDM  can be used as Mux/Demux two/four optical nWDM channels/wavelengths into a single-mode fiber, with channel spacing of 400GHz, each transmitting at100Gb/s, 200Gb/s or higher speed signals.
The nWDM Filter Block is Telcordia-1221/1209-CORE compliant and are commercially available in various sub-assembly.
