Why do you may need a fiber identifier and what can it do for you?



When you've got ever noticed a telephone company technician operating around the phone jump box outside your house, it is best to have noticed a unique handheld phone like instrument. The technician uses it to identify the incoming telephone wires by tapping onto the wires and listening to get a tone. Once he finds the appropriate wire, he connects the wire into your house.

For the duration of fiber optic network installation, maintenance, or restoration, it is also normally essential to recognize a distinct fiber without disrupting live service. This battery powered instrument appears like a lengthy handheld bar and is named fiber identifier or live fiber identifier.



How does it work?



There's a slot around the major of a fiber optic identifier. The fiber below test is inserted into the slot, then the fiber identifier performs a macro-bend around the fiber. The macro-bend tends to make some light leak out from the fiber as well as the optical sensor detects it. The detector can detect each the presence of light and the direction of light.



A fiber optic identifier can detect "no signal", "tone" or "traffic" and additionally, it indicates the traffic direction.



The optical signal loss induced by this strategy is so compact, typically at 1dB level, that it does not cause any trouble on the live traffic.



What type of fiber cables does it support?



Fiber optic identifiers can detect 250um bare fibers, 900um tight buffered fibers, 2.0mm fiber cables, 3.0mm fiber cables, bare fiber ribbons and jacketed fiber ribbons.



Most fiber identifiers want to adjust a head adapter as a way to support all these kinds of fibers and cables. Although some other models are cleverly developed and they don't have to have to transform the head adapter at all. Some models only support single mode fibers and other people can support both single mode and multimode fibers.



What exactly is relative power measurement



Most high end fiber optic identifiers are equipped using a LCD display which can display the optical power detected. On the other hand, this power measurement cannot be used as a accurate absolute power measurement of your optical signal resulting from inconsistencies in fiber optic cables plus the impact of user approach around the measurements.



But this power measurement might be used to evaluate power levels on distinctive fiber links which have similar form of fiber optic cable. This relative power measurement has a great deal of applications as described beneath.



Sample applications



1. Identification of fibers



The relative power reading might be used to aid in the identification of a live optical fiber.There are numerous tests that can be performed to isolate the desired fiber cable from a group of fibers with no taking down the hyperlink(s). Three strategies that could possibly be used involve comparing relative power, inducing macrobends, and varying the optical power with the supply. No single method is finest or necessarily definitive. Using one or possibly a combination of those procedures might be required to isolate the fiber.



2. Identification of high loss points



Fiber optic identifier's relative power measurement capability can be used to recognize high loss point(s) within a length of fiber. By taking relative power measurements along a section of optical fiber which is suspected of obtaining a higher loss point including a fracture or tight bend, the alter in relative power point to point can be noted. If a sudden drop or improve in relative power in between two points is noted, a high loss point possibly exists between the two points. The user can then narrow in on the point by taking further measurements among the two points.



3. Confirm optical splices and connectors



Fiber optic identifier may be used to verify fiber optic connectors and splices. This test have to be performed on a lit optical fiber. The optical fiber is usually carrying a signal or be illuminated using an optical test supply. Attach fiber identifier to one side in the optical connector/splice. Read and record the relative optical power. Repeat the measurement around the second side of your connector/splice. Take the difference in between the reading around the second side and the 1st side. The difference need to be roughly equal towards the optical attenuation of your optical connector/splice. The measurement might be taken numerous instances and averaged to improve accuracy. If the optical fiber identifier indicates high loss, the connector/slice could be defective.



Manufactures supplying fiber optic identifiers



You can get fiber optic identifiers from Wilcom, Ideal, 3M, Fitel, Noyes and many much more producers. We choose Wilcom and Fitel products since both suppliers have really higher client satisfaction price.
