Three-Port Banded Filter
Product Family - 25GHz
Channel Spacing
solla-Q 25
The Bookham Technology solla-Q banded product
line is based on thin-film interference filter
technology. These three port devices form the basic
building for banded mux/demux and banded optical
add/drop multipexer (OADM) applications for 25GHz
channel spacing.
Features
Deep reflection isolation for
minimized coherent cross talk
Wide range of band
plans available
Low express channel loss
Flat transmission passband
for cascadability
Fewer skipped channels
12GHz clear channel allocation
Compliance
Telcordia 1221
