Fiber optic identifiers allow technicians to detect live optical signals safely and non-intrusively. By clamping onto a fiber, these devices sense signal presence, power direction, and modulation without interrupting service—an essential feature for troubleshooting active networks. Ideal for telecom, FTTH, and enterprise environments, fiber identifiers prevent accidental service disruption during testing or maintenance.
