Description
The Micron Optics FFP-TF2 Fiber Fabry-Perot (FFP) Tunable Filter is a specialized filter based on
the all-fiber Fabry-Perot etalon technology. The FFP tunable filter passes wavelengths that are
equal to integer fractions of the cavity (etalon) length; all other wavelengths are attenuated
according to the Airy function.
The key to the elegant design of the FFP tunable filter is the lensless fiber construction. There
are no collimating optics or lenses, thus the FFP tunable filter achieves high finesse and
maintains a low loss transmission profile. Micron Optics has eliminated the pitfalls of other
Fabry-Perot component technologies, including misalignment, environmental sensitivity, and
extraneous modes.

•t Low power requirements
•t Qualified for Telcordia GR 2883
•t All-fiber platform
•t Compact for OEM application
The all-fiber FFP tunable filter follows the Airy function so closely that engineers can design it
into the opto-electronic systems with a high degree of confidence that it will provide results
very close to the theoretical mathematical model. Low loss, high isolation, and accurate
power or wavelength measurements are just a few of the characteristics resulting from an
ideal Airy function.
The FFP-TF2 design provides improved etalon alignment for stable long-term, high reliability,
and Telcordia-qualified performance at a more attractive price. Several standard low-cost
configurations are readily available for quick delivery. Custom high performance multi-band
configurations are also available for special uses including sensing, biotech, and scientific
applications. Options available include full-band tuning from 1260nm to 1620nm along with
the largest finesse range in the industry (from finesse 10 to 16,000). The FFP-TF2 is not a direct
drop-in replacement for the original FFP-TF (due to drive voltage and packaging differences),
but these filters are now more suitable in many volume applications.
Products displaying the “Micron Optics Tuned” logo include Micron Optics tunable technologies insuring high quality and performance.
