The Dual OWL 850/1300 is a cost-effective, compact, handheld light source with temperature-compensated outputs calibrated to couple -20dBm of optical power into multimode fiber. Equipped with an 850nm source, it can be upgraded to add a 1300nm option. The two-button interface offers simple operation, with one button for power and the other for wavelength selection. LED indicators highlight the selected source and confirm sufficient battery power for calibrated output.

Key Benefits:

  • Highly stabilized
  • Temperature Compensated
  • -20dBm Calibrated Output (Customizable)
  • Compact, Rugged & Economical
  • Extended Battery Life
  • Low Battery Indicator
  • NIST Traceable
