True or False: The red light emitted from a Visual Fault Locator (VFL) is visible at the fault location.

The statement that the red light emitted from a Visual Fault Locator (VFL) is visible at the fault location is true. A VFL is a device used primarily in fiber optic installations to identify faults within a fiber optic cable. It works by injecting a visible light, typically red, into the fiber.

When there is a fault, the light escapes at the location of the break or bend, making it visible to an operator. This allows the technician to easily locate the fault by observing the emitted light's point of escape. The visibility of the light at the fault location is key to the effectiveness of the VFL, as it aids in quickly identifying issues in the fiber optic network, thus streamlining the troubleshooting process.
