Fiber optic lines are an essential part of modern telecommunication infrastructure. Often buried underground, the lines are made of thin glass or plastic fibers that carry information in the form of light signals.
Fiber optic lines have a higher bandwidth than traditional copper wires. Additionally, they can transmit data over longer distances without signal degradation. However, finding these prolific cables with traditional metal detecting locators can be challenging since the lines are not made of metal or conductive materials.
Ground-penetrating radar (GPR) can provide a more accurate location for buried lines. At GPR Arkansas, our expert technicians use high-frequency radio waves to create images of the subsurface, which can be used to identify the location and depth of buried objects, including optical fiber lines.
GPR can also provide more detailed information about the location and condition of buried utilities, which can help prevent accidental damage during excavation.
Fiber optic lines are usually buried underground, which protects them from physical damage and environmental factors.
The burial depth depends on several factors, such as the local soil conditions, other underground utilities, and local regulations. Generally, fiber optic lines are buried at a depth of 12 to 18 inches (30 to 45 centimeters). However, in rocky or hard soil areas, the depth may be increased to 36 inches (91 centimeters).
GPR uses high-frequency radio waves to create images of the subsurface. When the radio waves encounter an object with a different density, such as a fiber optic line, they reflect back to the surface and create an image that shows the object’s location.
Knowing the location of buried lines is crucial before starting a building project. Failure to identify buried utilities before digging can lead to severe accidents, service disruptions, and costly repairs.
Accidentally cutting a fiber optic line can disrupt internet and phone services for an entire neighborhood. This can lead to financial losses for businesses and inconvenience for residents. In some cases, it can also pose a safety risk for workers and the public.
Before starting any construction work that involves digging, it is essential to conduct a thorough survey of the site. You should identify the location of all buried utilities, including fiber optic lines.
Underground locating services like Call 811 or Call Before You Dig typically mark and locate fiber optic lines.
However, it is important to note that the markings provided by these services are only intended to give an approximate location of the utilities, and they may not always be accurate or up-to-date.
GPR provides more precise information about the location and condition of buried utilities, which can help to prevent accidental damage during excavation.
