Wilcom F6121A Basic Single Mode/Multimode Fiber Identifier

Wilcom Part No.: F6121A

  • $ 1,969.00 or

The Wilcom Model F6121A Optical Fiber Identifier identifies optical fibers by detecting the optical signals being transmitted through a single-mode or multimode fiber.

By utilizing local detection technology (non-destructive macro-bend detection), the unit eliminates the need to open the fiber at the splice point for identification; eliminating the probability of interrupting service.

It operates by inserting fiber into the top of the unit which performs a macro-bend on the fiber. This bending technique allows the unit to detect the presence of light and the direction of light.

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; 900µm buffered fiber, ribbon or 250µm coated fiber, and 3mm jacketed fiber.

A 2mm optional adapter is also available for testing 2mm cables. It is not included in the standard package and needs to be ordered separately.
