The Jonard Tools OFI-100 is an Advanced Optical Fiber Identifier with a built-in Power Meter and Visual Fault Locator (VFL). This device accurately identifies the direction and frequency of traffic (270Hz, 1KHz, 2KHz) with an audible warning. The LCD screen clearly displays the relative core power, signal direction, and remaining battery life. The reversible adapter accommodates 2 mm and 3 mm fiber optic cables on one side, and 250 µm and 900µm on the other. The built-in VFL allows for quick and easy fault-finding in fiber cables, while the Power Meter measures power using a variety of wavelengths (850, 1300, 1310, 1490, 1550, and 1625 nm). Additionally, a protective rubber sleeve prevents damage from accidental drops. This kit also includes an adapter for different fiber sizes, two AA batteries, and a carrying pouch.
