   The Agilent/HP 83430A lightwave transmitter is a directly modulated DFB laser source for digital and analog testing up to 2.5 Gb/s. Designed for evaluating the performance of high-speed TDM (time division multiplexed) and WDM (wavelength division multiplexed) optical receivers and systems, it is SDH/SONET compliant.

User Adjustable Features

   The Agilent 83430A offers several user adjustable features:

  • Digital input threshold to obtain desired symmetry of optical one and zero levels
  • Wavelength select a preset or tune to a specific value within ±1.25 nm of center
  • Extinction ratio to simulate a wide range of optical signals

Test Capabilities in Systems

   The Agilent/HP 83430A can be used as a general optical source or combined with other instrumentation in systems to make a variety of measurements.

  • Optical parametric tests optical receiver sensitivity, dispersion power penalty of single-mode fiber (with an Agilent 71603A error performance analyzer and Agilent 83446A lightwave clock/data receiver).
  • Transceiver waveform testing including filtered conformance mask testing, extinction ratio, and eye diagram measurements (with an Agilent 83480A digital communications analyzer).
  • Jitter tolerance of recovered clock and data to determine the ability of a receiver to maintain communication in the presence of jitter (with an Agilent 71501C jitter and eye-diagram analyzer).
  • Performance testing for WDM optical MUX/DEMUX channels including BER and system variations caused by cross-phase modulation and Raman effect (with an Agilent 83446A lightwave clock/data receiver, Agilent 71603B error performance analyzer, and Agilent 86120B multiwavelength meter).

Wavelength Selection and Tunability

   The Agilent/HP 83430A wavelength adjustment gives you the ability to select a preset wavelength or to tune the wavelength to some specific value within ±1.25 nm of the center wavelength. This is accomplished by adjusting the temperature of the laser ±10°C about 25°C. Figure 2 shows the upper limit of the tunable range of the standard 1550 nm 83430A, the nominal wavelength and the lower limit of the range measured on the Agilent Optical Spectrum Analyzer.
