OTDRs
GAO Tek’s OTDRs are used in the field of fiber optics for testing and troubleshooting fiber optic cables. OTDR stands for Optical Time Domain Reflectometer.  OTDRs are designed to measure the characteristics of optical fibers, such as length, attenuation, and reflections. The main function of an OTDR is to send a short pulse of light into a fiber optic cable and analyze the reflected and scattered light that returns. This enables the OTDR to provide information about the fiber’s length, loss, and the locations of any faults or anomalies along the cable.

GAO’S OTDRs are composed of a laser source, coupler/splitter, optical circulator, photodetector, time measurement system, display, and control panel.

The other common names of OTDRs are OTDR devices, reflectometer units, fiber optic testers, optical cable analyzers, time-domain reflectometer tools, reflectometry systems, optical signal analyzers, fiber optic diagnostic equipment, cable testing instruments, reflective pulse analyzers, light pulse reflectors, fiber testing devices, optical reflection analyzers, pulse-echo testers, and time-of-flight analyzers.

GAO’s OTDRs have the following functions:

  • Distance Measurement: GAO’s OTDRs can accurately measure the length of a fiber optic cable by analyzing the time it takes for the light pulse to travel through the fiber and return. This helps in determining the physical distance between two points in the cable.
  • Loss Measurement: Our OTDRs measure the signal loss (attenuation) along the fiber optic cable by analyzing the strength of the reflected or backscattered light. This allows technicians to identify areas of excessive loss and pinpoint the locations of splices, connectors, or breaks that may be causing the loss.
  • Fault Localization: GAO’s OTDRs are used to locate faults or anomalies in fiber optic cables, such as breaks, bends, or high loss points. By analyzing the differences in reflection or backscatter patterns, technicians can identify the exact locations of these faults and plan for necessary repairs or replacements.
  • Reflectance Measurement: Our OTDRs can detect and measure the amount of light reflected at different points in the fiber optic cable. This reflection measurement helps in evaluating the quality of connectors, splices, and other components by assessing their ability to minimize signal reflections.
  • Fiber Characterization: Our OTDRs provide information about the overall quality and performance of fiber optic cables. They can assess parameters such as fiber attenuation, splice and connector loss, and fiber uniformity, helping technicians evaluate the suitability of the fiber for specific applications.

GAO Tek’s OTDRs are rugged, versatile, and precision measurement instruments. They comply with applicable industry standards such as IEC 61010, IEC 60529, TIA-568, ANSI/TIA-1096-A, and MIL-STD-1344.
