The key of Preserving Your Fiber Optic Network
Why do you will need a fiber identifier and what can it do for you?
Should you have ever observed a phone company technician functioning around the phone jump box outside your house, you need to have noticed a special handheld phone like instrument. The technician uses it to determine the incoming telephone wires by tapping onto the wires and listening to get a tone. When he finds the appropriate wire, he connects the wire into your house.

In the course of fiber optic network installation, upkeep, or restoration, it truly is also generally necessary to recognize a precise fiber without disrupting live service. This battery powered instrument looks like a extended handheld bar and is known as fiber identifier or live fiber identifier.
How does it work?
There is a slot on the top rated 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 in the fiber and also the optical sensor detects it. The detector can detect each the presence of light along with the direction of light.
A fiber optic identifier can detect "no signal", "tone" or "traffic" and in addition, it indicates the traffic direction.
The optical signal loss induced by this approach is so tiny, normally at 1dB level, that it does not lead to any difficulty 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 need to have to modify a head adapter so as to support all these sorts of fibers and cables. Though some other models are cleverly developed and they don't have to have to modify the head adapter at all. Some models only support single mode fibers and others can support each single mode and multimode fibers.
What is relative power measurement
Most higher end fiber optic identifiers are equipped with a LCD display which can display the optical power detected. On the other hand, this power measurement cannot be used as a correct absolute power measurement of the optical signal resulting from inconsistencies in fiber optic cables and the influence of user strategy on the measurements.
But this power measurement is often used to evaluate power levels on distinct fiber links which have identical form of fiber optic cable. This relative power measurement features a great deal of applications as described below.
Sample applications
1. Identification of fibers
The relative power reading is usually used to help in the identification of a live optical fiber.There are many tests that may be performed to isolate the preferred fiber cable from a group of fibers devoid of taking down the hyperlink(s). 3 approaches that could be used include things like comparing relative power, inducing macrobends, and varying the optical power on the source. No single method is most effective or necessarily definitive. Using one or maybe a mixture of those approaches could possibly be necessary to isolate the fiber.
2. Identification of high loss points
Fiber optic identifier's relative power measurement capability is often used to recognize high loss point(s) within a length of fiber. By taking relative power measurements along a section of optical fiber that's suspected of obtaining a higher loss point such as a fracture or tight bend, the modify in relative power point to point could be noted. If a sudden drop or enhance in relative power amongst two points is noted, a high loss point probably exists among the two points. The user can then narrow in on the point by taking further measurements in between the two points.
3. Verify optical splices and connectors
Fiber optic identifier is usually used to verify fiber optic connectors and splices. This test should be performed on a lit optical fiber. The optical fiber can be carrying a signal or be illuminated using an optical test supply. Attach fiber identifier to one side from the optical connector/splice. Study and record the relative optical power. Repeat the measurement on the second side from the connector/splice. Take the difference involving the reading around the second side and the first side. The distinction ought to be roughly equal towards the optical attenuation from the optical connector/splice. The measurement is usually taken many occasions and averaged to enhance accuracy. In the event the optical fiber identifier indicates high loss, the connector/slice may very well be defective.
Manufactures supplying fiber optic identifiers
You can get fiber optic identifiers from Wilcom, Excellent, 3M, Fitel, Noyes and a lot of a lot more producers. We prefer Wilcom and Fitel products given that each suppliers have really higher consumer satisfaction price.
