Agilent/Keysight 83493A Lightwave Source Module

The Agilent/Keysight 83493A is an optical clock recovery module that extracts timing signals from optical data streams, enabling parametric testing and signal integrity analysis without a direct reference clock. The module integrates into Agilent/Keysight 86100 family oscilloscopes via plug-in architecture and operates across single-mode fiber (9/125 µm) in the 1200–1600 nm wavelength band.

• PLL Bandwidth (Internal Triggering): 50–70 kHz
• PLL Bandwidth (External Output): 4–5 MHz
• Output Jitter: < 0.0125 UI RMS
• Input Return Loss: 28 dB
• Input Insertion Loss: 1.55 dB
• Fiber Type: Single-mode (9/125 µm)

– Key Features

• Built-in coupler/splitter reduces external triggering hardware requirements
• Clock recovery from optical data streams independent of reference signal availability
• FC/PC optical input connectors (9/125 µm)
• Auxiliary recovered clock outputs via Type N with SMA adapters
• Low output jitter performance for high-fidelity timing measurements

– Typical Applications

• Telecommunications signal integrity analysis
• Data communications testing across multiple protocol speeds
• Parametric measurements on optical receiver modules
• Clock recovery in systems lacking direct timing references

– Compatibility & Integration

Designed exclusively for Agilent/Keysight 86100 family oscilloscopes (86100A/B/C Infiniium DCA/DCA-J). Operates with single-mode fiber only; multimode fiber use will produce significant reflections and insertion loss. Optical connectors and adapters such as the 81000xI Series may be purchased separately.
