Tunable Bandpass Filter

The AgileWaveTM Tunable Bandpass Filter (TBF)is the first 50GHz tunable filter to scan or set along the entire C-band wavelength range. The TBF is a digitally programmable filter module that enables precise routing and monitoring of individual DWDM channels in optical telecommunication networks.

Based on CiDRA's proprietary optical waveguide technology and tunable Bragg grating technology, the first product release accurately scans or sets a narrow 50GHz filter to any wavelength within the C-band with a simple digital command. CiDRA's TBF features a unique electronic control circuit that eliminates the need for wavelength referencing.

Immediate applications for CiDRA's TBF module include remote signal routing, high-resolution optical performance monitoring, channel selectors for local bit error rate testing and high-end photonics test and measurement equipment. CiDRA offers a standard 50GHz module covering the C-band as well as original equipment manufactured modules based on specific customer applications and functional requirements. The AgileWaveTM TBF comes in a stand-alone package or can be made in card form for ready installation into customer equipment.
