Why do you need a fiber identifier and what can it do for you?
Should you have ever noticed a phone company technician functioning on the phone jump box outdoors your house, you'll want to have noticed a specific handheld phone like instrument. The technician uses it to determine the incoming phone wires by tapping onto the wires and listening to get a tone. When he finds the correct wire, he connects the wire into your house.
Through fiber optic network installation, maintenance, or restoration, it can be also often necessary to identify a certain fiber without the need of disrupting live service. This battery powered instrument looks like a lengthy handheld bar and is named fiber identifier or live fiber identifier.
How does it work?
There's a slot on the top rated of a fiber optic identifier. The fiber below test is inserted in to the slot, then the fiber identifier performs a macro-bend on the fiber. The macro-bend tends to make some light leak out from the fiber plus the optical sensor detects it. The detector can detect both the presence of light along with 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 method is so modest, usually at 1dB level, that it does not lead to any trouble around the live traffic.
What sort 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 have to have to adjust a head adapter so that you can support all these types of fibers and cables. Whilst some other models are cleverly developed and they don't need to adjust the head adapter at all. Some models only support single mode fibers and other folks can support both 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. Even so, this power measurement can't be used as a accurate absolute power measurement of the optical signal on account of inconsistencies in fiber optic cables along with the impact of user method on the measurements.
But this power measurement could be used to examine power levels on various fiber hyperlinks which have identical sort of fiber optic cable. This relative power measurement features a lot of applications as described beneath.
Sample applications
1. Identification of fibers
The relative power reading is often used to aid within 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 without taking down the link(s). 3 methods that could be used include comparing relative power, inducing macrobends, and varying the optical power of the source. No single method is most effective or necessarily definitive. Using one or even a combination of those strategies can be required 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) in a length of fiber. By taking relative power measurements along a section of optical fiber that is suspected of obtaining a high loss point which include a fracture or tight bend, the modify in relative power point to point may be noted. If a sudden drop or improve in relative power amongst two points is noted, a high loss point in all probability exists amongst the two points. The user can then narrow in around the point by taking further measurements involving the two points.
3. Confirm optical splices and connectors
Fiber optic identifier could be used to confirm fiber optic connectors and splices. This test has to be performed on a lit optical fiber. The optical fiber might be carrying a signal or be illuminated using an optical test source. Attach fiber identifier to one side of your optical connector/splice. Read and record the relative optical power. Repeat the measurement on the second side of the connector/splice. Take the distinction in between the reading on the second side along with the initially side. The difference needs to be roughly equal for the optical attenuation with the optical connector/splice. The measurement is often taken numerous occasions and averaged to improve accuracy. If the optical fiber identifier indicates higher loss, the connector/slice could be defective.
Manufactures supplying fiber optic identifiers
You will get fiber optic identifiers from Wilcom, Excellent, 3M, Fitel, Noyes and a lot of extra manufacturers. We prefer Wilcom and Fitel products since each suppliers have extremely high consumer satisfaction price.
