TMCORPORATION

Tunable Optical Filter
Optoplex’s Tunable Optical Filter, including Tunable Bandpass Filter and Tunable Edge Filter, isan integrated module, consisting of micro-optics and electronics. When receiving a stream of opticalsignals of a plurality of wavelengths from the Input-Port (IN), the 2-port Tunable Optical Filter directs aselected channel to the Output-Port (OUT). The selected channel can be varied (tuned) within theoperating wavelength (frequency) range by a remote command sent through the built-in control PCBand firmware.
Optoplex’s Tunable Optical Filter is based on a patented micro-optic design and thin-film filter coatingtechnology. The thin-film filter used in the optical tunable filter is similar to those already widely usedin DWDM devices. The wavelength tuning is achieved by varying the incident angle of the incoming
light beam on the thin-film filter. Each single device is optimized to cover either C- or L-bandwavelengths. The standard optical tunable filter product family supports 100- and 50-GHz channelspacing.
