D
Band Filters for 200GHz
Add/Drop Multiplexing
Bookham band skip filters leverage the proprietary
Advanced Energetic Deposition (AED) process to
produce the industry’s best banded filter solution.
The AED process features state-of-the-art layer
thickness control to produce thin-film interference
filters that are unparalleled for optical add/drop
multiplexing (OADM) WDM applications.
Standard 5.5mm diameter packaging is available with the
boot/length specification needed to meet your
application. The optional compact packaging has
diameter of only 3.2mm. All Bookham filter components
are Telcordia GR-1221 qualified and 5/6 RoHS compliant.
