Integrated 4 Channels DWDM for High Speed Transceivers
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 (others are also available upon request). It has ultra-low insertion loss (<1.3 dB)
and compact size (6.5x10x25mm) and is a good candidate for DWDM PON applications as well as
DWDM transceivers.
