MARCH 3, 2010 -- Alliance Fiber Optic Products, Inc. (AFOP) has unveiled an improved small form factor pluggable (SFP) variable optical attenuator (VOA) that integrates an electrically controlled VOA into a standard SFP module.

The SFP VOA incorporates the company’s iC^|VOA technology, which is designed to offer high optical performance and low cost (see "AFOP's iC^lVOA line is customizable"). Convenient electronic attenuation control is achieved using the industry standard I²C interface.

Applications include power equalization in multichannel optically amplified networks, gain tilt, and optical power control in reconfigurable networks.

The device exhibits low excess loss and covers the complete fiber-optic communication wavelength range, AFOP asserts. Customized electronic interfaces and layout are available upon request.
