NanoOpto and SpectraSwitch introduce compact, electronically controlled Free Space Variable Optical Attenuator

Fiber Optics Weekly Update, March 21, 2003

NanoOpto Corporation, which is applying proprietary nano-optics and nano-manufacturing technologies to design and manufacture optical components for systems and networks, and SpectraSwitch Inc., who delivers integrated active components for optical networks, announced the availability for sampling of the Lambda Processor Free Space Variable Optical Attenuator (FSVOA), created under a joint development agreement.

NanoOpto and SpectraSwitch have integrated nano-optic and nano-manufacturing with liquid crystal technology to create a low-cost, compact form-factor FSVOA. The electronically controlled variable optical attenuator and shutter is designed for free-space integration into a broad range of optical components. The initial release of the Lambda Processor FSVOA supports either C-band or C L-band wavelength ranges, provides up to 35dB of tunable attenuation, and has less than 0.4dB of insertion loss in a device 1.4 millimeters in thickness. The device is designed to comply with Telcordia GR-468-CORE requirements for use in carrier grade systems.

Initially targeted for transceivers, transponders and tunable lasers, the Lambda Processor FSVOA seamlessly integrates broad range, fine resolution attenuation in a robust platform without the size, cost and complexity of existing solutions. Its benefits include its ability to be integrated into the transceiver rather than being an external and separate device. This integration creates savings in board space, packaging, power, and control complexity, allowing more economical application of transceivers in access and enterprise applications.
