Tuneable Filters

2-Port Optical Tuneable Filter

2-Port Optical Tuneable Filter

Optoplex's Tuneable Optical Filter, also known as Optical Tuneable Filter or Tuneable 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 tuneable 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.

3-Port ROADM and TOADM

3-Port ROADM and TOADM

Optoplex's Reconfigurable Optical Add/Drop Multiplexer (ROADM) module, also known as Tuneable Optical Add/Drop Multiplexer (TOADM), is based on a proprietary micro-optics and micro-actuator design, athermal packaging technology, and state-of-the-art thin-film coating. When receiving a stream of optical signals of a plurality of wavelengths from the Input-Port (IN), this 3-port ROADM device directs a selected channel to the Drop-Port (ADD/DROP) and the remaining channels to the Express-Port (EXP), as depicted in the figure below. This tuneable feature can also be used for adding a channel, when the device is used in reverse. Cascading two ROADM modules, simultaneous add and drop functions can be achieved. Each single ROADM device is optimised to cover either C- or L-band wavelengths. The standard 100- or 200-GHz channel spacing ROADM products allow for single-channel drop. Customised banded-channel drop ROADMs are available upon request.

MEMS Tuneable Filter

MEMS Tuneable Filter

Optoplex’s MEMS Tuneable Optical Filter is based on a patented micro-optic design with MEMS tuning technology. It is an integrated module consisting of a MEMS chip, micro-optics and control electronics and interface. When receiving a stream of optical signals of a plurality of wavelengths from the Input-Port (IN), the 2-port tuneable optical filter directs a selected channel to the Output-Port (OUT). Wavelength (frequency) tuning is achieved by changing driving voltage applied to the MEMS chip, via the control electronics and the built-in firmware.

Tuneable Edge Filters

Tuneable Edge Filters

Tuneable edge filter is a customised product. It usually belongs to 2-port optical tuneable filter product platform. Instead of using narrow bandpass filter in the 2-port tuneable optical filter, the tuneable edge filter utilises a low-pass or long-pass interference filter. By changing the incident angle of the light beam, the cut-off wavelength will be tuned. Standard Tuneable edge filters support C-band or L-band wavelength range.

In other applications, Tuneable edge filter can be in 3-port configuration, in which one output is long pass and the other one is low pass.
