❓ Frequently Asked Questions

Q: What is the difference between the 5mW and 10mW TC-321 VFL?
A: The 5mW version detects faults up to ~5km and is ideal for FTTH drop cable and short-run testing. The 10mW version has a stronger laser for detection up to 10km, better suited for longer fiber runs or more demanding applications. For most FTTH work, the 5mW is sufficient.

Q: Is the TC-321 compatible with LC connectors?
A: The TC-321 uses a 2.5mm universal interface (SC, FC, ST). For LC connectors (1.25mm), a 1.25mm adapter is required (available separately).

Q: Is the laser safe?
A: Never look directly into the fiber end or connector while the VFL is active. Always follow standard fiber optic safety precautions.
