The Agilent/Keysight 8181A Optical Head is an accessory module designed to extend the 8181A programmable data generator into the optical domain. It converts electrical data streams into optical signals, enabling verification and characterization of optical components and systems. The optical head integrates with the 8181A mainframe to deliver modulated optical output at specified wavelengths and formats.
Technical Specifications
• Data Rate Compatibility: Supports up to 1 Gbps from the 8181A mainframe
• Modulation Format: User-configurable for various optical modulation schemes
• Output Impedance: Matched to the 8181A mainframe specifications
• Jitter Generation: Inherits jitter generation capabilities from host instrument for optical stress testing
– Key Features
• Direct integration with 8181A data generator
• Converts electrical patterns to optical domain without signal integrity loss
• Supports user-defined patterns, PRBS, and predefined test sequences
• Programmable phase and deskew control maintained across optical conversion
• IEEE-488 (GPIB) control interface via host mainframe
• Internal and external clock input options through mainframe connectivity
– Typical Applications
• Optical transceiver validation and characterization
• Fiber optic link testing at specified wavelengths
• Optical component stress testing with integrated jitter injection
• Digital-to-optical system integration verification
• Manufacturing and quality control for optical subsystems
– Compatibility & Integration
The 8181A Optical Head operates exclusively as an accessory to the Agilent/Keysight 8181A mainframe. It maintains full compatibility with the host instrument’s pattern generation engine, clock architecture, and control interfaces. Integration with existing digital test setups is preserved through the mainframe’s GPIB connectivity and standard optical output connectors.
