Which function is described by the phrase 'Tones/Locate light fiber'?

• A. Tones/Locate light fiber
• B. Break
• C. VFL
• D. dBm

Answer: (A)

The main idea behind this phrase is using a tone to trace and locate a specific fiber in a bundle or harness. In practice, a tone generator puts a distinctive signal onto the fiber at one end, and a tone probe or tracer detects that signal along the run or at the other end. The technician uses this audible or visual cue to identify which fiber is which, and to follow its path to locate the correct fiber or to verify it’s connected to the right circuit. This method is different from injecting light to see a break (that’s what a Visual Fault Locator does) or from measuring optical power (dBm) or identifying a break by loss of continuity. So the described function perfectly matches using tones to locate the light fiber.
