Includes: One Wilcom hand-held optical fiber identifier (F6-121A)

Non-destructive macro-bend detection!

The Wilcom OFI Model F6121A Probe is a rugged, hand-held, easy-to-use maintenance and installation instrument that identifies optical fibers by detecting the optical signals that are transmitted through a singlemode fiber. The F6121A utilizes non-destructive macro-bend detection, which eliminates the need to identify a fiber by opening it at the splice point. The probability of interrupting service is eliminated. Signals that the F6121A detect include continuous wave live optical transmission, and low frequency modulated tones at 270, 1000, and 2000 Hz. When the F6121A detects traffic on a fiber being tested, one of two LEDs on the F6121A illuminates to indicate the presence and direction of transmission. The presence of tone is indicated by illumination of one of three LEDs (Figure 1). The F6121A also has an easy to use thumb lock feature for hands-free operation.
