The Wilcom Model F6121A Basic Optical Fiber Identifier is a rugged, easy-to-use installation and maintenance instrument which identifies optical fibers by detecting the optical signals being transmitted through a fiber. By utilizing local detection technology (non-destructive macro-bend detection which does not damage or overstress the fiber), the unit eliminates the need to open the fiber at the splice point for identification; eliminating the probability of interrupting service.

The Optical Fiber Identifier detects low frequency tones at 270 Hz, 1000 Hz and 2000 Hz. When traffic is present on the fiber under test, an audible tone can be heard as well as the traffic direction which is indicated by LEDs illuminating on the probe.

During installations, maintenance, rerouting, or restorations it is often necessary to isolate a specific fiber without disrupting service. A light source such as Wilcom’s Model FS1316 used in conjunction with the Optical Fiber Identifier can make the job a lot easier.

The Optical Fiber Identifier includes a carrying pouch containing three easy to use field interchangeable adapter heads to accommodate; 900 µm buffered fiber, ribbon or 250µm coated fiber and 3mm jacketed fiber.


Rugged Metal Case
The F6121A OFI uses the same field proven lightweight rugged metal housing as the rest of Wilcom’s Optical Fiber Identifier product line.

850nm to 1700nm Range
With the use of InGaAs detectors, the unit can be used on singlemode and multimode applications.

Audible Tone
The unit provides an audible tone in the presence of a fiber optic signal.

Tone Detection
The F6121A OFI can detect 270Hz, 1kHz and 2kHz tones for easy fiber cable identification

LED Indication
LEDs indicate tone detection, Traffic presence, Traffic Direction, and Low Battery.

With an easy to use thumb lock, hands-free operation can be enabled and disabled.

Condition: Refurbished
Warranty: 90 Day Exchange
