True or False: It is recommended to always confirm that transmitting devices are turned off before an endface inspection.

• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (A)

Safety first: always confirm that transmitting devices are off before inspecting an endface. When a fiber link is powered, optical power can reach the endface you’re examining, and even modest laser light can pose eye safety risks if it somehow travels toward you. Powering down the transmitter also prevents back-reflections or stray light from re-entering the source, which could damage equipment or skew inspection results. De-energizing the system creates a safe, stable environment for cleaning and examining the connector, reducing the chance of accidental exposure or equipment harm. If power were left on, you’d face unnecessary laser exposure risk and potential measurement or equipment issues, so this is the prudent, standard practice.
