Ultra-Narrow Bandwidth-Variable Tunable Filter

Main Features

• Unprecedented sharpness?1500dB/nm roll-off

• Unprecedented narrowness: min. bandwidth 30pm (3.7GHz)

• Flexible: both bandwidth and wavelength-tunable

Main applications

• DWDM system channel selection

• Optical signal noise filtering

• Laboratory &RD

Ultra-Sharp Edge Roll-Off

The filter exhibits an ultra-sharp roll-off of 1500dB/nm (12dB/GHz),without compromising the flexibility of bandwidth and wavelength tuning. Ideal for DWDM channel selection and removing ASE noise.

Continuously-Tunable BW: 0.03 to 3nm

The 3dB bandwidth is 30pm (3.7GHz) at its narrowest, and is also continuously tunable to 3nm (370GHz).Filtering of<1GHz optical frequency comb lines is also possible by combining with etalons.
