Wilcom Enhanced Single Mode/Multimode Fiber Identifier with Power Display for CATV

Wilcom Part No.: F6222C

  • $ 2,450.00 or

The Wilcom Model F6222C 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.

F6222C provides all features found on the F6121A model plus that F6222C can display Relative Core Power which is helpful in identifying bad connectors, splice points, etc.

The difference between F6222 and F6222C model is the detectable Core Power: F6222 can detect -40dBm to 0dBm while F6222C can detect -20dBm to +20dBm which is optimized for the CATV industry.

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.

Wilcom's Optical Fiber Identifiers are rugged metal units that provide you with the best sensitivity detection on the market today.  You can use these versatile fiber identifier devices for both your single-mode and multimode fiber optic applications. These optical fiber identifiers operate by inducing a macro-bend in the fiber optic cable, which enables the unit to detect the presence and direction of light within the optical fiber. You can also use the optical fiber identifier to detect the presence of 2kHz, 1kHz or 270Hz modulated tones, and certain Wilcom models display Relative Core Power Measurements. 

Wilcom Optical Fiber Identifiers are part of the extensive line of fiber optic test and inspection equipment available from FIS. These include fiber optic Light Sources, Power Meters, OTDR's, Loss Test Sets, Fiber Identifiers, Microscopes, Visual Fault Locators, and Continuity Testers.

The optical head on the Wilcom Optical Fiber Identifier accepts 3mm, 250µm, Ribbon, or 900µm fibers. A 2mm head is also available. Wilcom Optical Fiber Identifiers are supplied with a 9V alkaline battery and carry case.
