Luna’s Optical Backscatter Reflectometer (OBR) is ideally suited for troubleshooting both single mode and multi-mode optical networks. This engineering note details the advantages and disadvantages of three methods of mode conditioning: 1) direct launch method 2) full equilibrium mode launch 3) partial mode launch.

LUNA’s Optical Backscatter Reflectometer (OBR) is well suited for making localised Insertion Loss (IL) measurements in reflection using the differences in fibre Rayleigh scatter amplitude on either side of a loss event. This engineering note details how the use of a circulator can allow the user to measure the total IL of their Device Under Test (DUT) in transmission. Click...

This engineering note details two methods of coupling light from single mode fiber to multi-mode fiber to produce stable and repeatable Insertion Loss (IL) and Return Loss (RL) measurements with LUNA’s Optical Backscatter Reflectometer (OBR). This note also discusses the differences between IL and RL results for the two mode launch conditions and details the consequences for OBR spatial resolution...

LUNA’s Optical Backscatter Reflectometer (OBR) is ideally suited for measuring Insertion Loss (IL) and Return Loss (RL) in optical networks with extremely high spatial resolution. This engineering note details how to properly compute insertion loss by measuring the relative difference in scatter levels. Click here to download the full article

Overview Planar optical waveguide technologies are the key elements in the modern, high speed optical network. Recent broad deployment of optical and hybrid optoelectronic chips and planar light circuits (PLCs) has been driven by the cost, size and operational benefits that these architectures offer. From a measurement perspective, planar optical waveguide architectures offer several unique challenges. Even the highest quality...

EssentOptics, a leading producer of UV-VIS-MWIR spectrophotometers for optical coaters, sets a new benchmark for the effective wavelength range of this type of spectrophotometer instrument and announces the expanded Mid Wave IR (MWIR) range configurations for its Photon RT spectrophotometers. By Mid-wave Infrared (MWIR) we are referring to the 3 to 5 µm atmospheric window which is typically covered by detectors...

Lock-in amplifiers are used to detect and measure very small AC signals, all the way down to a few nanovolts. Accurate measurements may be made even when the small signal is obscured by noise sources many thousands of times larger. Lock-in amplifiers use a technique known as phase-sensitive detection to single out the component of the signal at a specific...
