The H-OADM2x4-xxx-yyy-4C is a bi-directional 2ch DWDM add/drop filter, designed with a channel passband width that can accommodate 400G 16QAM signals. This filter is a member of the 400G compatible filter family, as indicated by the "-4C" suffix in the part number. The product range includes ten distinct filter products that collectively cover 20 channels from 921 to 940. Additional channels up to 960 can be provided upon request.
This filter features two add/drop ports and a Line port facing the "east" direction, with an identical configuration for the "west" direction. Channels that fall outside the add/drop channel bands are passed through the filter. The channel band from Extension to Line ports ranges from 1460 -1630nm, allowing for signals such as OTDR to pass through the filters.
The monitor ports (Mon) extract 1% of the transmitted and received Line signal, offering the capability to monitor the channel power levels via a connected Optical Channel Monitoring (OCM) device or an optical spectrum analyzer. The DWDM channels are in compliance with ITU-T G.694.1.
The product line includes ten different filters that cover the channel band from 921 to 940. These are: H-OADM2x2-921-922-4C, H-OADM2x2-923-924-4C, H-OADM2x2-925-926-4C, H-OADM2x2-927-928-4C, H-OADM2x2-929-930-4C, H-OADM2x2-931-932-4C, H-OADM2x2-933-934-4C, H-OADM2x2-935-936-4C, H-OADM2x2-937-938-4C, and H-OADM2x2-939-940-4C.
