Description - Tunable Optical
Filter
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.

Reconfigurable
Optical Add/Drop Multiplexer (ROADM) page.
