This DWDM device is based on free space and thin-film filter technology. It eliminates the cascade
structure that causes high insertion loss and takes big footprint for fiber routing.The channel
spacing is 100GHz/200GHz (others are also available upon request). It has ultra-low insertion loss (<2.5 dB)
and compact size ( 6.5x21.0x24.0 mm ) and is a good candidate for DWDM PON applications as well as
DWDM transceivers.
