Frequently Asked Questions

Q: What fiber types does this work with?
A: Compatible with single-mode (SM) and multimode (MM) fiber optic cables commonly used in FTTH, LAN, and telecom installations.

Q: How do I charge it?
A: Via USB — the built-in 1800mAh battery charges with a standard USB cable (included).

Q: What does the 15mW rating mean?
A: It refers to the laser output power. 15mW is strong enough to visibly illuminate faults through fiber jackets in most field conditions.

Q: Can I use this to test cable length?
A: This is a visual fault locator, not an OTDR. It identifies fault locations visually but does not measure cable length or loss in dB.

Q: Is it safe to look into the laser?
A: Never look directly into the fiber end or laser aperture while the device is active. Always follow standard laser safety practices.
