Bookham narrowband 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. A 
range of 100GHz single channel filters are available. 
100 Standard 
This product is intended for construction of multiplexer 
and demultiplexer systems.  It provides high performance 
and lowest cost. 
100 OADM 
This product features improved performance for 
reflection isolation, transmission isolation and chromatic 
dispersion.  This part is designed for more demanding 
applications such as channel by channel optical add/drop 
multiplexing or lower chromatic dispersion mux/demux 
designs. 
100 Wide-Top 
This product features the widest available clear channel 
width.  Wider clear channel provides for less rounding of 
the channel passband after the cascading of filters.  The 
wider clear channel also allows for the wider spectral 
width of high-chirp lasers or 40Gb/s modulation rates.  
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.
