A complete Closed-Loop Digital Variable Optical Attenuator
System-On-a-Chip. The DVOA integrates functionalities of 16
discrete optical and electronic components into a single small
module.
The DVOA integrates both the optical control (input/output
optical couplers, optical interconnects and photodiodes) and
electronic control (log-amps, micro-converter and other peripherals)
in a single, small and self-sealed 42x17x10mm package sealed
at a wafer level.
The DVOAs unique feature-set and high integration provides
the following benefits:
1. It enables engineers to achieve substantial savings in
direct cost (70%) and direct footprint (95%).
2. It significantly simplifies the design and operation of
complete optical boards.
3. Its integrated optical interconnect eliminates the external
fiber coupling and splicing for better manufacturability.
The DVOA on-board microprocessor control, alarm reporting
capabilities, on-board Input/Output Optical Power Monitor,
automatic calibration, Optical Automatic Power Control (OAPC)
and its continuous power adjustment to environmental changes
and aging makes it an attractive plug and play and maintenance
free solution.
