Which piece of test equipment uses a red laser light?

• A. BFL
• B. OTDR
• C. Power meter
• D. Inspection scope

Answer: (A)

Visible red laser light is used for alignment and targeting in some fiber tools. This piece of equipment includes a red laser diode that projects a bright, narrow beam, making it easy to visually sight the fiber end and line up connectors or terms before testing. The red cue beam provides a simple, direct reference you can see with the eye, which is exactly what’s needed for precise alignment tasks. In contrast, an OTDR sends infrared pulses into the fiber to generate a backscatter trace, a power meter simply measures light without emitting a beam, and an inspection scope uses illumination and imaging (often white light) to view the fiber end-face rather than providing a visible laser alignment beam. That combination of a built-in visible red laser for alignment is what makes this equipment the match.
