Single-Channel Variable Optical Attenuator (VOA)

w249.png

Lightwaves2020's liquid crystal based variable optical attenuator array (AVOA) is a voltage-controlled module designed specifically for power management in optical networks. Each device in the module has a dynamic range of up to 40dB attenuation and operats in the C-band, L-band or C+L band.

Eight VOAs packaged in small footprint make it ideal for integration onto circuit boards and for saving space. The module is driven by a 0-5V DC voltage using a easy-to-plug 12 pin electric interface connector.

As with all Lightwaves2020's products, the VOA conforms to Telcordia requirements.
