The basic symbols used in FTA are grouped as events, gates, and transfer symbols. Minor variations may be used in FTA software. Event symbols. Event symbols are used for primary events and intermediate events. Primary events are not further developed on the fault tree. Intermediate events are found at the output of a gate.

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. 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 events include ghosts, gainers, hidden, and unplanned loss events. Figure 2 shows examples of events on an OTDR trace. 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.

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. Figure 8. The OTDR pulse length limits its resolution . There is a tool that will help here.

OTDR (Optical Time-Domain Reflectometer) is such a powerful test instruments for fiber optic cable testing: when used properly, it not only simplifies testing requirements, but also help to increase the reliability and value of the network.

Chapter 2 Optical Pulse Measurement (OTDR). 2.1 the results are displayed using icons for each event type. To use this Detail, file name only, user defined. The OH- symbol identified in the graph indicates that at the wavelengths of 950 nm, attenuation (or loss), for a given wavelength, is defined as the ratio between the with an automatic ORL measurement while measuring an OTDR trac OTDR is a test instruments for fiber optic cable testing. What is OTDR. How does to do fiber OTDR testing. Set OTDR parameters to ease OTDR trace interpret.

Attenuation is a characteristic showing how much power (dB or dBm) is lost at a given location (attenuation at splice, cross) or in a given section of the duct. Kilometric attenuation is attenuation per unit length. OTDR Test Modes: Display Features Press tabs to perform the following: 1 Home - display OTDR setup, change Fiber and Cable ID parameters. 2 Settings - define OTDR test setup. 3 Event - define Events settings and Pass/ Fail Settings. 4 Job Settings - define Job, End Locations, and Operator parameters.

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.

Ensure that you clearly understand the meanings of the symbols and take the necessary precautions BEFORE using the equipment. The large event you see right in front of the instrument on the OTDR trace is caused by crosstalk within the instrument and reflectance from the connector on the face of the OTDR.

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. However, even a trained and experienced OTDR operator may have difficulty interpreting a fiber trace at times.

Event (or reflective) and attenuation (or nonreflective) are the two main types of dead zones. The event dead zone represents the minimum distance between the beginning of a reflective event and the point where a consecutive reflective event can be detected. 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 Since the fiber optic connector on the OTDR will have cables plugged into it every time the OTDR is used, it generally becomes dirty and scratched, even if it’s regularly cleaned – as it should be. Likewise the launch cable used to reduce the effect of the reflection at the OTDR connector often suffers from too many connections to cables OTDR: Optical Time Domain Reflectometer.
