The JDS Uniphase IA3 is a precision optical attenuator module designed for variable optical attenuation (VOA) in high-speed data communication systems. This compact cassette-type module integrates into the JDS Uniphase MAP (Modular Access Platform) chassis and delivers microprocessor-controlled attenuation across C-band and L-band wavelengths. The IA3 operates without power tracking and communicates via I2C, SPI, or UART interfaces for seamless integration into automated optical transport networks.
