DWDM Filter

DWDM Filter

DWDM filter also called as DWDM device, it’s an individual passive component available from ITU channels 186.6 to 196.1 THz with 100Ghz channel space, which always used in DWDM multiplexers as DWDM Mux Demux. Arkoptics manufacture DWDM filter components with Thin-Film-Filter(ie.TTF) technology...

DWDM filter also called as DWDM device, it’s an individual passive component available from ITU channels 186.6 to 196.1 THz with 100Ghz channel space, which always used in DWDM multiplexers as DWDM Mux Demux.
 
Arkoptics manufacture DWDM filter components with Thin-Film-Filter(ie.TTF) technology using 5.5 x 34mm stainless steel tube package, coming out with 250um bare fiber or 900um patches, can terminated with LC,SC,FC,ST and other types of connector on request.
