The Viavi 2311/26 SmartClass Fiber ORL-85 Optical Return Loss Meter, 1310/1490/1550/1625 nm, APC, combines fiber inspection, optical power meter (OPM), light source (OLS), and continuous wave return loss meter (OCWR) in one versatile test instrument. The compact instrument is ideal for measuring optical return loss and inspecting fiber connector end faces to verify optical connection quality.

Optical systems with high-speed lasers, analog transmission (CATV), or Raman amplifiers require high return loss for maximum performance. Furthermore, optical return loss measurements can be used to prove that an installation was completed carefully and accurately; for example, they can show that the optical connectors were inspected and are clean. The ultrasensitive power meter combined with stabilized light sources enable up to a 70 dB measurement range. The angled single-mode test port (APC) guarantees highly accurate return loss measurements without requiring external termination for up to 50 dB return loss measurements.

The ORL-85 is compatible with the P5000i digital analysis microscope (sold separately) for checking fiber end-face quality and getting pass/fail acceptance results at the push of a button.

Threshold settings for pass/fail indications and the intuitive touch screen user interface transforms users into instant fiber experts without the need for special training. Automatic functions, such as Auto-λ and real-time Multi-λ functionalities avoid handling errors and speed up test time significantly. The ORL-85 is fully compatible with other members of the SmartClass Fiber family (OLS, OLP, and OLT) with these automatic functions.

Users can easily save test results (power, return loss, and fiber inspection) with real-time stamp to generate certification reports. Test results can be easily uploaded to a PC for post-processing with FiberChekPRO PC software.

The ORL-85 optical return loss meters can be used anywhere today's fiber technicians go, up poles or down holes. Technicians gain ultimate flexibility and performance from this powerful easy-to-use solution that can instantly transform any technician into a fiber expert.
