Jonard Tools OFI-100 Advanced Optical Fiber Identifier

Rapidly identify live fiber traffic and diagnose links with the Jonard Tools OFI-100 Advanced Optical Fiber Identifier — a compact fiber optic tester built for field technicians and network professionals. This OFI-100 combines a non-intrusive identifier that shows signal direction and relative core power with an integrated visual fault locator and precision power meter covering common wavelengths (850, 1300, 1310, 1490, 1550 and 1625 nm). The reversible adapter supports both 2.0/3.0 mm and 250/900 µm fibers, so you can switch between cable types without extra tools. Audible tones for 270 Hz, 1 kHz and 2 kHz traffic and an easy-to-read LCD speed inspections and reduce guesswork. Lightweight and protected by a rubber sleeve, the unit runs on standard AA batteries and includes a carry pouch for secure transport. Ideal for installers and maintenance teams working in networking, security, surveillance and monitoring applications, the OFI-100 helps you troubleshoot faster and preserve live links. Add the OFI-100 to your toolkit to streamline fiber testing and minimize service interruptions.

• Non-intrusive traffic identification: quickly detect live light direction and relative core power without disrupting networks to reduce downtime
• Integrated troubleshooting tools: built-in VFL and power meter (850–1625 nm) let technicians locate faults and verify links with one device
• Multi-fiber compatibility: reversible adapter supports 2.0/3.0 mm and 250/900 µm fibers for flexible field use
• Clear visual and audible alerts: LCD shows signal direction, relative power and battery life while audible tones identify 270 Hz, 1 kHz and 2 kHz signals
• Rugged, portable design: protective rubber sleeve, included pouch and AA batteries make it reliable for on-site security, surveillance and networking work
