  • Page 14: Otdr Basic Principles

    OTDR Basic Principles OTDR Basic Principles An OTDR sends short pulses of light into a fiber. Light scattering occurs in the fiber due to discontinuities such as connectors, splices, bends, and faults. An OTDR then detects and analyzes the backscattered signals. The signal strength is measured for specific intervals of time and is used to characterize events.
  • Page 15 Introducing the IDEAL OTDR OTDR Basic Principles An OTDR uses the effects of Rayleigh scattering and Fresnel reflection to measure the fiber condition, but the Fresnel reflection is tens of thousands of times greater in power level than the backscatter.

    The analysis ended before reaching the end of the fiber because the signal-to-noise ratio was too low.

    Description of Event Types Launch Level Launch Level Reflected power (dB) Launch level event position Second event Launch level Linear area Distance (km) This event indicates the level of the signal launched into the fiber. The figure above shows how the launch level is measured. A straight line is plotted using least-square approximation to fit all trace points in the linear area between the first and second detected events.

  • Page 111: Fiber Section

    Detected events are distinct—even if they cover more than one point on the trace. A loss value is specified for fiber section events. No reflectance is specified for this type of event. Each fiber section has its own length, attenuation and loss value. OTDR...

    In the example above, the launched pulse hits the third connector, is reflected back to the OTDR and reflected again into the fiber. It then reaches the third connector a second time and is reflected once more to the OTDR.

  • Page 113: Echo

    In the example above, the launched pulse travels up to the end connector and is reflected back toward the OTDR. Then, it reaches the second connector and is reflected again toward the end connector. It is then reflected back to the OTDR.

    Description of Event Types Merged Reflective Event Merged Reflective Event Reflected power (dB) Reflective events Point A Δ Total loss ( Point B Merged Reflective event position Distance (km) This symbol denotes a reflective event combined with one or more other reflective events.
  • Page 115 The total loss (Δ dB) equals the power difference between the point where the first event begins (point A) and the point on the projected straight line located just below the first event (point B). No loss value can be specified for the subevents. OTDR...

  • Page 116: Reflective Event

    Description of Event Types Reflective Event Reflective Event Reflected Clipped level power (dB) Reflective events Distance (km) Reflective faults appear as spikes in the fiber trace. They are caused by an abrupt discontinuity in the index of refraction. Reflective events cause a significant portion of the energy initially launched into the fiber to be reflected back toward the source.
