81613A Agilent Fiber Optic Equipment

The 81613A is a InGaAs Return Loss Module from Agilent.

Additional Features:

  • Built-in Power Monitor and Laser Source
  • Built-in step-by step guided wizard with Keysight Agilent HP 8163B mainframe
  • Factory calibrated values
  • Return loss dynamic range > 75dB
  • Return loss uncertainty down to ±0.2dB with broadband source
  • Wide operating wavelength range: 1250nm to 1640nm

Agilent's 81613A used test equipment Return Loss module is the tool of choice for measuring return loss (RL) and reflection of single-mode fiberoptic components. The module measures the optical power into and reflected back from the device under test and calculates and displays the return loss. Thorough built-in functionality provides the correct coupling and detection ratios and eliminates the effects of dark current and residual backscatter in the instrument setup to provide accurate measurements over a wide dynamic range.

The Return Loss modules can be used in any Agilent 816x Lightwave mainframe and with the internal Fabry-Perot light source or an external fixed-wavelength or tunable laser source. The performance and usability is enhanced by combination with an Keysight Agilent HP power sensor in the Agilent 8163B mainframe for simultaneous RL and insertion loss measurements, especially in combination with the Agilent 81610CC calibrated reference cable. Automated use is supported by the Agilent 816x Plug&Play Driver, which also supports use of the module for advanced swept-wavelength RL measurements.
