This bending technique allows the unit to detect the presence of light and the direction of light.\u003c\/p\u003e\n\u003cp\u003eThe Optical Fiber Identifier detects low-frequency tones at 270 Hz, 1000 Hz, and 2000 Hz.

The F6121A utilizes non-destructive macro-bend detection, which eliminates the need to identify a fiber by opening it at the splice point. Thus, the probability of interrupting service is eliminated.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eSignals that the F6121A detect include continuous wave live optical transmission, and\u003cbr\u003elow frequency modulated tones at 270, 1000, and 2000 Hz. When the F6121A detects\u003cbr\u003etraffic on a fiber being tested, one of two LEDs on the F6121A illuminates to indicate\u003cbr\u003ethe presence and direction of transmission. The presence of tone is indicated by illumination of one of three LEDs (Figure 1).\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"display: block; margin-left: auto; margin-right: auto;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1026\/4509\/files\/Screenshot_2024-12-16_at_1.17.50_PM.png?v=1734383899\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eThe F6121A also has an easy to use thumb lock feature for hands-free operation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOperating the F6121A\u003c\/strong\u003e\u003cbr\u003eOperation of the F6121A is simple, as outlined in the following steps:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eChoose an adapter head for the type of fiber to be tested.\u003cbr\u003eThe F6121A is supplied with three adapters (as shown in Figure 2): (A) foam-covered, to accommodate 900 µm buffered fiber; (B) smooth-surfaced with foam perimeter, for\u003cbr\u003euse with ribbon fiber or a 250 µm coated fiber; and (C) slotted, for 3 mm and optional 2 mm jacketed fiber (i.e., pigtails and jumpers) or loose tube fiber.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003e\u003cimg style=\"display: block; margin-left: auto; margin-right: auto;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1026\/4509\/files\/Screenshot_2024-12-16_at_1.24.11_PM.png?v=1734384277\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e        2.
