DuPont Intros VOA Arrays

WILMINGTON, Del. -- DuPont Photonics Technologies, a provider of practical integrated optical components and a wholly owned subsidiary of DuPont, introduces its integrated variable optical attenuator (iVOA) arrays based on planar lightwave circuitry (PLC). The cost-effective iVOA arrays are ideal for use in intelligent wavelength division multiplexing (WDM) systems and optical add drop multiplexer (OADM) modules for channel and band balancing, power control and dynamic gain equalization.

Based on DuPont's library of proven optical building blocks, the iVOA family of products integrates up to 40 channels of variable optical attenuators on a single chip. DuPont's VOA arrays operate across C and L bands with low insertion loss, low polarization dependent loss (PDL), low wavelength dependent loss (WDL), low temperature dependent loss (TDL), low power consumption, high dynamic range, and simple electronic control. The iVOA chips are hermetically packaged to provide excellent reliability. In addition, the iVOA products have no moving parts and are stable to mechanical vibrations.

"Enabled by our powerful materials and advanced design, our iVOA arrays provide the highest performance among PLC VOA arrays," said Chuck Xu, vice president of marketing and business development at DuPont Photonics. "And by integrating multiple channels of VOA's on a single chip, we are able to offer our customers significant component savings in both cost and space, in addition to eliminating the cost associated with assembly of bulky discrete components and complex fiber management."
