FTTx Filter Chips
Bookham narrowband filters leverage the
proprietary Advanced Energetic Deposition (AED)
process to produce the industry’s best filter
solutions. The AED process features state-of-theart layer thickness control to produce thin-film
interference filters for FTTx PON applications. A
range of specification options are available.
Fiber to the X (home, curb, business, etc) is an emerging
market destined to bring high bandwidth to users. The
most common architectures employ either twowavelength or three-wavelength designs to transport
data, voice and video. Bookham makes solutions for the
wide number of arrangements of laser, filters and
detectors that are unique to each manufacturer.
Bookham FTTx filters provide the high isolation required
between the 1310nm laser and the detectors, which is
especially important for rejection at the analog video
detectors at 1550nm. Bookham filters also give superior
performance at high angle of incidence and with
imperfectly collimated optical beams.
