Page 12: Section 3. Basic Otdr Information
930XC-20C • 930XC-20M • 930XC-30F • 930XC-30P Section 3. Basic OTDR Information Principle of OTDRs An OTDR (Optical Time Domain Reflectometer) is a measurement instrument for identifying optical fiber transmission features. The OTDR is used to measure the overall attenuation of a fiber optic link and to provide details relating to the position of each event in that link. -
Page 13: Measurement Application
930XC-20C • 930XC-20M • 930XC-30F • 930XC-30P When some pulse energy is scattered, reflection events occur. When reflection events occur, a peak is displayed on the trace (Figure 3-1). Measurement Application The 930XC instruments display power relating to the distance of returning signals. This information can be used to identify the main properties of an optical fiber chain. -

Page 18: Pulse Width Configuration
930XC-20C • 930XC-20M • 930XC-30F • 930XC-30P Pulse Width Configuration The selection of pulse width affects the dynamic range and resolution of the measurement. With a narrow pulse width there will be higher resolution and smaller deadzone; however, the dynamic range will be decreased. A wide pulse width will bring higher dynamic range and measure comparatively longer distance, but resolution and deadzone will be increased. -
