FFP-TF2
Fiber Fabry-Perot Tunable Filter

PDF download

The Micron Optics Fiber Fabry-Perot (FFP) tunable filter is a specialized optical tunable filter based on Fabry-Perot etalon technology. The FFP tunable filters 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.

The all-Fiber FFP tunable filter follows the Airy function so closely that engineers can design it into their 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 special uses including sensing, biotech, and scientific applications. Option 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 new FFP-TF2 is not a direct drop-in replacement for the original FFP-TF (due to drive voltage and packaging differences), but these new filters are now more suitable in many volume applications.

Applications
  • Optical Performance Monitoring

  • Tunable Optical Noise Filtering

  • Tunable Channel Drop for Ultra DWDM



Optical Performance Monitoring.
Micron Optics' FFP Technology is the base for the highest performance optical performance monitor available today, monitoring up to 400 channels in the C band alone. The high resolution, deep dynamic range and continuous tuning combine to allow accurate dense channel analysis. For example, Micron Optics finesse 10,000 filters have a contrast factor of 76 dB.

Tunable Optical Noise Filtering & Channel Locking.
Micron Optics' FFP Technology is used in telecom systems around the world for optical noise filtering and dynamic channel locking. A key attribute is the extreme low loss nature (to < 1.5 dB) of the filter and its reliable locking capability. Data from thousands of filters in the field has shown a projected reliability of less than 80 FITs. The resulting benefit is an extremely low bit error rate and high network receiver sensitivity.

Tunable Channel Drop for Ultra DWDM
(<25 GHz spacing). The rapid tuning and locking capabilities of Micron Optics' FFP Technology enables reliable channel selection and dropping applications in dynamic optical networks. The high degree to which the FFP filters follow the Airy Function theory allows optical engineers to accurately design system performance parameters, without the overhead of allowing for imprecise measurements.
