Bookham narrowband filters lev erage the
proprietary Advanced Energetic De position (AED)
process to produce the industry’s best filter
solutions. The AED process features state-of-the-
art layer thickness control to produc e thin-film
interference filters for FTTx PON appl ications. A
range of specification options are available.
Fiber to the X (home, curb, business, etc) is an emergin g
market destined to bring high bandwidth to users. The
most common architecture s emp l oy either two-
wavelength or three-wavelength designs to transport
data, voice and video. Bookham makes solutions for the
wide number of arran gements of laser, filters and
detectors that are unique to each manufactu rer.
Bookham FTTx filters provide the high isolation required
between th e 1310nm laser and the detectors, which is
especially important for rejection at th e an alog video
detectors at 1550nm. Bookham filters also give superior
performance at high angle of incidence and with
imperfectly collimated optical beams.
