Description
The Chameleon Thin Film Tunable Filter (CTF-TF) is an optical component capable of tuning and dropping a designated wavelength in the C or L-Band. Unlike other tunable filter technologies,Micron Optics Chameleon Thin Film Tunable Filters exhibit flattopped bandpasses, allowing the selection of a channel without distorting the signal or degrading the bit error rate.

The Micron Optics Chameleon Thin Film Tunable Filter is a break-through technology that exhibits polarization-insensitive angle tuning properties across the S-, C- or L-band. Conventional angletuned thin film filters use expensive and complex diversity optics to overcome the divergence of S- and P-polarization bandpasses.Micron Optics has designed thin film filters whose S- and P-polarization bandpasses track one another across the band.

Conventional designs, materials and manufacturing processes are used, resulting in rugged, reliable, and inexpensive filters. The CTF-TF is also highly customizable and adaptable to a wide range of products, from ASE noise suppression to tunable add/drops.Micron Optics Chameleon Thin Film Tunable Filters can be custom engineered to meet a wide range of specifications and uses.

Channel Selector
Micron Optics Chameleon Thin Film Tunable Filters allow network operators to select and isolate any DWDM channel in the C-band or L-band for biterror- rate testing, protocol-layer analysis and dynamic network development.

Optical Performance Monitoring
Insertion loss is an industry-leading 2 dB. The CTF's wide dynamic range, short response time and high measurement sensitivity enable very fast and accurate power measurements and accurate channel counts with high OSNR.
