Liquid Crystal Based Wide-Band Variable Optical Attenuator

Lightwaves2020’s liquid crystal based variable optical attenuator (VOA) is
a voltage-controlled device designed specifically for power management in
optical networks. The device has a dynamic range of up to 40dB attenuation
and wide operating band of wavelength from 1260nm to 1620nm.
Sealed in a compact coaxial package 7.2mm in diameter, the VOA’s small
footprint makes it ideal for integration onto circuit board. In addition, it
offers the benefits of no moving parts, precision attenuation control without
backlash, small driving voltage, low insertion loss and low cost. The
VOA is driven by either a 0 ~ 40V peak to peak 10KHz square wave or by
a 0 ~ 5 V DC voltage using Lightwaves2020’s easy-to plug driver board.
The VOA can be used for pre-emphasis of DWDM laser signals in long
haul systems, power equalization in optical add/drop modules and optical
cross-connects, as well as gain-tilt adjustment in EDFA. As with all
Lightwaves2020’s products, this wide-band VOA conforms to Telcordia
requirements.
