SmartClass ORL-55 Optical Return Loss Meter (Discontinued)

A SMART Future-Proof Optical Return Loss Meter

High-performance instrument for field, production, and lab; operates as return loss meter, optical power and loss meter, and laser source.

The ORL-55 is a high performance instrument for field, production and lab use. This instrument can be used in three different modes as a return loss meter, optical power/loss meter and a laser source.


  • Ensures quick and reliable testing of the return loss of an optical system. High return loss values are essential for ensuring the signal quality especially with CATV & FTTx networks.
  • Measures return loss at up to three wavelengths simultaneously in real time using digital signal processing.
  • Return loss referencing performed via a single key stroke. Very easy referencing due to ultra stable lasers and special signal processing.
  • Can be used as a standalone optical return loss meter, an optical power/loss meter and a laser source.
  • USB interface for easy remote control & report generation
  • Internal memory for over 1000 results
  • New Visual Fault Locator Option
  • New Host USB data storage option


  • Designed for fiber optic field use for technicians and Installers/maintenance people within fiber optic networks especially for FTTX, CATV and high bandwidth installations.

Key Features

  • Auto-lambda function provides automatic wavelength detection to speed up testing.
  • 70% reduction in testing time due to multiple automatic functions.
  • Industries first auto-zeroing function for very high accuracy with no manual zeroing needed.
  • SMARTEnergy power supply management system.
  • SMARTStar graphical user interface for fast and easy operation.
  • Quick start function requiring no warm up reduces testing time.
  • Robust shock proof instrument with great look and feel.
