By NATE BROWN, FIS -- Optical Time Domain Reflectometers (OTDRs) are a valuable tool for measuring the performance of optical cables. They are often used to create a "picture" of a fiber optic cable when it is first installed so later comparisons can be made to help with troubleshooting network problems. l Events that show much more dispersion (pulse broadening). l Events that show no loss.

In other words, it is the minimum length of fiber needed between two reflective events. Still using the car example mentioned above, when your eyes are blinded by another car, after a few seconds you could notice an object on the road without being able to properly identify it. OTDR, the full name of which is "Optical Time Domain Reflectometer". The OTDR depends on two types of optical phenomena: Rayleigh Backscattering and Fresnel Reflections: 1.Rayleigh scattering is intrinsic to the fiber material itself and is present along the entire length of the fiber. 2.Fresnel reflections are "point" events and occur only where the fiber comes in contact with air or another OTDR trace for an optical fiber. What are OTDR ‘Ghosts’ and how can they be distinguished from real events? Due to single-ended measurement technique where OTDR measures back-scattered light which is not the actual amount of light received at the end of the optical fiber, an OTDR trace can also show unreal events called ‘ghosts.’ events which are useful for the data post-processing OTDR data.

Rate it: OTDR: Optical Time-Domain Reflectometer The OTDR functions by looking for “Events” in a fiber, for example, irregularities or splices.

DSX Cable Analyzer series, with Versiv modular design supports copper certification, fiber optic loss, OTDR testing.

There is a trick you can try if you are desperate. The reflection at an event that causes overloading the OTDR receiver can be tamed by using "index matching fluid" to reduce the effect that causes the reflection. The reflection is caused by an air gap between the ends of the fibers.

OTDR Pulse Width Attenuation dead zone The minimum distance needed after a reflective event in order to perform a loss measurement. It is the distance between: Beginning of event Point on trailing edge where receiver detects +0.5 dB from normal backscatter level -2.00-4.00-6.00-8.00-10.00 100.00 110.00 120.00 130.00 140.00 150.00 160.00 dB

The event dead zone is the minimum distance after a Fresnel reflection where an OTDR can detect another event.

The OTDR only needs to have access to one end of a fiber to make its measurements. interprets each OTDR event and represents it as a simple icon for easy understanding.

15 Dublin Workshop event 15 • Measuring distance » To calculate the speed of light, the OTDR must know the Index of Refraction (IOR). » The IOR is a ratio between the speed of light in a vacuum and the speed of light in a fibre. » The IOR is obtained from the fibre manufacturer, entered into the OTDR by the user and must be accurate. OTDR

2.Fresnel reflections are "point" events and occur only where the fiber comes in contact with air or another OTDR trace for an optical fiber. What are OTDR ‘Ghosts’ and how can they be distinguished from real events? Due to single-ended measurement technique where OTDR measures back-scattered light which is not the actual amount of light received at the end of the optical fiber, an OTDR trace can also show unreal events called ‘ghosts.’ events which are useful for the data post-processing OTDR data. Some methods are discussed in this section.

At first, the OTDR trace can seem a bit overwhelming. The OTDR trace tells a story about each fiber it tests. A certain dip or spike known as an event can reveal the type of connection. Lets take the example below: This link has pretty much every type of event … The event dead zone (EDZ) is the minimum distance that distinguishes two consecutive unsaturated reflective events. Here the events are more closely spaced than the EDZ and are shown as one event. It can be reduced using smaller pulse widths. Event Dead Zone Distance Range specifies the distance that the OTDR will display on the X axis Loss dB Event Type Definition Possible Cause OTDR Port The tester’s OTDR port connector.
