solla-Q CWDM filters
solla-Q CWDM
The Bookham Technology solla-Q narrowband filter
product line is based on thin-film interference
technology. These filters are produced with Bookham
Technology's proprietary Advanced Energetic
Deposition (AED) III technology.
solla-Q CWDM filters
Bookham Technology offers a range of filtering solutions for
CWDM channel spacing. The standard product offers a wide
15nm passband and 15dB reflection notch depth. Bookham
Technology offers a high-performance solution with extended
wavelength reflectivity down to 1250nm and 16nm passband
for added flexibility in full spectrum CWDM applications.
Accessory filters for routing bands of CWDM channels are also
available. Custom designs for high angle of incidence CWDM
applications are available upon request.
