However, while a regular OTDR takes one averaged trace at a time with one When performing a measurement, the iOLM will try to match the defined launch and icons may appear when the fiber length is out of the recommended range.
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. l Events which are repetitive at equal distances down the OTDR trace.If a highly reflective connector with high power loss is located at a distance D, the OTDR’ ghost’ will appear at 2D, and also at distances multiples of D. Another place this problem shows up is in splice closures. An OTDR may show a bad splice, but it can actually be a crack or stress point somewhere else in the splice closure.
An OTDR simply generates a pulse inside a fiber to be tested for faults or defects. Different events within the fiber create a Rayleigh back scatter. Pulses are returned to the OTDR and their strengths are then measured and calculated as a function of time and plotted as a function of fiber stretch. OTDR Reflective and Non-Reflective Events. OTDR (Optical Time Domain Reflectometer) is widely used in all phases of a fiber system's life, from construction to maintenance to fault locating and restoration.
News The SLM intelligent optical software application helps technicians use an OTDR more effectively, without the need to understand or interpret OTDR results. Each event is displayed as an icon giving users a schematic view of the entire link, known as SmartLink. SLM can completely correlate to the original OTDR trace as experts desire.

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
But a more confusing effect of reflections is what we commonly call “ghosts,” confusing events that show up on the The Event Dead Zone (EDZ) is the minimum distance where two consecutive unsaturated reflective events can be distinguished. In this case, the events are more closely spaced than the EDZ and shown as one event.

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

Identifies each event on the network and obtains straightforward fiber link status via Optical Link View Provides prompt diagnosis enabling network issues to be fixed quickly and efficiently Generates OTDR …
In reviewing the above OTDR trace, the first event that we see is the connector. This is a reflective event and should be present on any fiber trace. This is a Fresnel Reflection. If you look through a plate of glass at night, you can see your reflection in the glass as well as see what is on the other side of the glass.

FIS Advanced OTDR Manual Rev.K 2/2012 - 1 - 1.0 OTDR Quick Start Guide Press to turn on the OTDR. The OTDR function will be highlighted. Press to initiate the OTDR application. Connect the fiber to the appropriate port.
An expert fiber technician can usually identify these types of events on a trace without the help of an automatic event analyzer and event table that many OTDRs now possess. 2019-09-01
The event dead zone is the minimum distance after a Fresnel reflection where an OTDR can detect another event. In other words, it is the minimum length of fiber needed between two reflective events.
