Datasheet

Overview

The VIAVI SmartClass Fiber ORL-85 is a compact, battery-operated field instrument. It combines an optical power meter (OPM), an optical light source (OLS), a continuous-wave optical return loss meter (OCWR) and fiber connector inspection in one unit.

Optical systems that use high-speed lasers, analog transmission (CATV) or Raman amplifiers need high return loss to perform at their best. Return loss measurements can also show that an installation was done carefully, for example that the optical connectors were inspected and cleaned. The ORL-85 pairs a sensitive power meter with stabilized light sources, which gives a measurement range of up to 70 dB.

The single-mode test port has an angled (APC) connector. It can measure return loss up to 50 dB without external termination.

Return loss

Return loss is the power that a discontinuity in a transmission line reflects back towards the source. The discontinuity can be a mismatch with the terminating load or a device inserted in the line. Return loss therefore shows how well devices and lines are matched: when the impedance match is good, the energy passes through and little is reflected.

Inspection and data handling

With the optional P5000i microscope, the instrument inspects fiber connectors and gives an automated pass/fail result. It stores inspection images and test results with a time stamp. Data can be transferred, and the instrument controlled remotely, over USB or Ethernet. VIAVI provides SmartClass Fiber software for the instrument.
