Description
The Micron Optics Chameleon Thin Film Channel Selector incorporates a Chameleon Thin Film
Film Tunable Filter (CTF-TF) and the associated electronics driver to enable agile tuning and selection of arbitrary wavelengths. The CTF Channel Selector tunes a thin-film filter while maintaining flat-top bandpass and steep adjacent channel rejection. A designated wavelength or range of wavelengths may be selected using a graphical user interface or through an analog input. The user may automatically or manually step through a wavelength range by selecting a scan increment. The CTF Channel Selector is internally calibrated and does not need an external
wavelength reference. The selected wavelength is displayed and only differs from the input wavelength when the filter is tuning.

For ease of testing and laboratory use, Micron Optics supplies:
    • Visual Basic Interface (source code included) which allows direct input/output of wavelength        values
    • PCMCIA card and cable for laptop computer

Features
• Tunable over entire C or L bands
• Flat-topped bandpass
• Low Polarization Dependent Loss (PDL)
• Fast tuning
• Low insertion loss
• Self-calibrated
  (external wavelength reference not required)

Applications
• Channel Selector for Test and Measurement
• Optical Performance Monitoring
• Tunable Filter for Dynamic Networks
• Tunable Narrow-band Source Development

Channel Selector

Micron Optics' Chameleon Thin Film Channel Selector allows network operators to select and isolate any DWDM channel in the C-band or L-band for bit-error-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.
