2-Port Optical Tunable Filter
Description
Optoplex's Tunable Optical Filter, also known as Optical Tunable Filter or Tunable Bandpass Filter, is an integrated module, consisting of micro optics and electronics. When receiving a stream of optical signals of a plurality of wavelengths from the Input-Port (IN), the 2-port tunable optical filter directs a selected channel to the Output-Port (OUT). The selected channel can be varied (tuned) within the operating wavelength (frequency) range by a remote command sent through the built-in control PCB and firmware.
Optoplex's Tunable Optical Filter is based on a patented micro-optic design and thin-film interference filter coating technology. The thin-film filter used in tunable optical filter is very similar to those already widely used in 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-band wavelengths. The standard tunable optical filter product family supports 100- and 50-GHz channel-spacing.
