  2. B
    Time-Domain Reflectometer (TDR)
  3. C
    Tone generator and probe
  4. D
    Loopback plug

Cevap

Optical Time-Domain Reflectometer (OTDR)
An Optical Time-Domain Reflectometer (OTDR) is designed for optical fiber testing. It sends light pulses through the fiber cable and measures the power and timing of reflected light backscatter to determine total attenuation and locate splices, breaks, or signal loss points.

Adım Adım Çözüm

1
Identify the transmission medium specified in the scenario.
The cable run consists of single-mode optical fiber.
Fiber-optic cables carry light signals rather than electrical currents, requiring diagnostic tools specifically designed for optical analysis.
2
Determine the diagnostic requirement.
The objective is to measure signal attenuation and locate light loss along the fiber cable.
Optical Time-Domain Reflectometers (OTDRs) measure light degradation and calculate distance to faults by evaluating backscattered light pulses.
