Frequently Asked Questions

Q: What wavelengths does the TC-350 OTDR support?
A: The TC-350 support 1310/1550 two wavelengths or 1310nm wavelength.

Q: Does it work with both FC and SC connectors?
A: No. The TC-350 come only with FC or SC connector compatibility. Universal adapters are available for other connector types.

Q: How long does the battery last?
A: Up to 150 hours of continuous use on a single 1200mAh lithium battery charge. Auto power-off activates after 30 minutes of inactivity.

Q: Is the TC-350 suitable for data center use?
A: Yes. Its wide wavelength range and high accuracy make it ideal for verifying fiber patch panels, transceivers, and backbone links in data center environments.

Q: What is the difference between the TC-350 and a standard optical power meter?
A: The TC-350 combines optical power measurement with optional VFL and RJ45 cable tracing in a single handheld device, eliminating the need to carry multiple tools.
