Overview
The Jonard Tools OFI-100 is a versatile, multi-function tool designed for field identification and verification of optical fiber networks. This advanced fiber identifier allows technicians to detect signal direction and transmitted traffic without the need to disconnect the fiber or disturb existing network traffic.
Engineered for high utility in diverse environments, the OFI-100 combines a fiber identifier, an optical power meter (OPM), and a visual fault locator (VFL) into a single, compact device. It features an intuitive LCD interface that provides real-time data on signal direction, relative core power, and battery status. Housed in a durable protective rubber sleeve, it is suitable for demanding field conditions.
