Users Manual

Operating Manual The FiberFox OFI Model SFI-10B 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 SFI-10B 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. Signals that the SFI-10B detect include continuous wave live optical transmission, and low frequency modulated tones at 270, 1000, and 2000 Hz. When the SFI-10B detects traffic on a fiber being tested, LCD display on the SFI-10B illuminates to indicate the presence and direction of transmission. The presence of tone is indicated in LCD display (Figure 1). The relative level of core power within the fiber is also displayed on the LCD display. Introduction Operating the SFI-10B Operation of the SFI-10B is simple, as outlined in the following steps: 1. Choose an adapter head for the type of fiber to be tested. The SFI-10B is supplied with two adapters (as shown in Figure 2): (A) foam-covered, to accommodate 250 μm bare fiber and 900 μm buffered fiber; (B) foam-covered, for 3 mm and 2 mm jacketed fiber (i.e., pigtails and jumpers) or loose tube fiber. 2. Push adaptor cover, as shown in Figure 3. 3. Select the appropriate adapter and slide it into the mating slotted channel of the body with slight downward pressure, as shown in Figure 4. 4. Pull adaptor cover Figure 1 Figure 2 A B Figure 3 Figure 4 Presence of Traffic. Arrow of either Traffic Right/Left indicates the detection and direction of traffic. This is useful in determining whether the fiber is transmitting or receiving at equipment terminal locations. (refer to Figure 6) Test Tone Detection. Display of any one of the 2 kHz, 1 kHz, or 270 Hz indicates that a test tone is being detected, which ensures accurate identification of the fiber that is under test. (refer to Figure 6) Relative Power Level. The relative core power in the fiber is displayed as a minus dB value between 0 and -40 dBm. Low Battery Indication. When the battery voltage becomes low, low gage is displayed after the self test. The unit will continue to operate for some time, but the battery should be replaced with a fresh 1.5 -volt alkaline battery x 2ea as soon as possible. (refer to Figure 6) Maintenance. It is important that the optical ports remain clean and free of dust, dirt, grease, or other foreign matter. Cleaning with lint-free swabs and isopropyl alcohol is recommended for optimum performance Figure 5 Figure 6 Test Tone Traffic Battery 5. Insert the fiber to be tested between the adapter and the top of the clamp (refer to Figure 5). Ensure that the fiber is installed properly in the alignment groove and pull the thumb switch downward. Warnings and Cautions The SFI-10B has been designed for discriminating signals in optical fibers. Do not attempt to use this instrument for other applications. Misuse of the instrument may result in electric shock and/or serious personal injury. •Read this instruction manual carefully before operating this instrument. •Store this instruction manual in a safe place. •Contents of this instruction manual may change without announcement. Warnings and Cautions Components Components SFI-10B Front Side a . R ule Part 15.19(a)(3): This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. b . R ule Part 15.21: The users manual or instruction manual for an intentional or unintentional radiator shall caution the user that changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. N ote: This equipment has been tested and found to comply with the limits for a Class B digital N OTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help Description SFI-10B Back Surface SFI-10B Bottom Side Power Supply Battery Operation 1.By using a driver remove the battery cover on the reverse side of the SFI-10 B. 2.Place batteries into the battery compartment on the orientation imprinted side of the compartment. 3.Put on the battery cover. * Caution: Risk of fire or explosion if the battery is replaced by incorrect type. Use AA Batteries (Voltage: 1.2 to 1.5 V). SPEC
