The key of Sustaining Your Fiber Optic Network

Posted by Thomas Shaw on December 10th, 2021

Why do you\'ll need a fiber identifier and what can it do for you?



When you\'ve got ever noticed a phone company technician functioning on the phone jump box outside your house, you should 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. As soon as he finds the right wire, he connects the wire into your house.

In the course of fiber optic network installation, upkeep, or restoration, it truly is also normally essential to identify a specific fiber devoid of disrupting live service. This battery powered instrument looks like a lengthy handheld bar and is called fiber identifier or live fiber identifier.



How does it work?



There\'s a slot around the top rated of a fiber optic identifier. The fiber under test is inserted in to the slot, then the fiber identifier performs a macro-bend around the fiber. The macro-bend makes some light leak out in the fiber along with the optical sensor detects it. The detector can detect both the presence of light along with the path of light.



A fiber optic identifier can detect \"no signal\", \"tone\" or \"traffic\" and it also indicates the traffic path.



The optical signal loss induced by this method is so smaller, ordinarily at 1dB level, that it does not lead to 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 need to transform a head adapter in order to support all these kinds of fibers and cables. Even though some other models are cleverly designed and they do not will need to transform the head adapter at all. Some models only support single mode fibers and other individuals can support each single mode and multimode fibers.



What exactly is relative power measurement



Most high end fiber optic identifiers are equipped with a LCD display which can display the optical power detected. However, this power measurement can\'t be used as a correct absolute power measurement with the optical signal resulting from inconsistencies in fiber optic cables and the influence of user technique on the measurements.



But this power measurement is often used to evaluate power levels on diverse fiber links which have same style of fiber optic cable. This relative power measurement features a large amount of applications as described under.



Sample applications



1. Identification of fibers



The relative power reading may be used to help in the identification of a live optical fiber.There are several tests that may be performed to isolate the desired fiber cable from a group of fibers with out taking down the link(s). 3 strategies that may 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 even a mixture of those methods can be required to isolate the fiber.



2. Identification of higher loss points



Fiber optic identifier\'s relative power measurement capability is usually used to identify high loss point(s) in a length of fiber. By taking relative power measurements along a section of optical fiber that\'s suspected of getting a high loss point for instance a fracture or tight bend, the alter in relative power point to point is often noted. If a sudden drop or improve in relative power among two points is noted, a high loss point possibly exists involving the two points. The user can then narrow in around the point by taking additional measurements between the two points.



3. Confirm optical splices and connectors



Fiber optic identifier might be used to verify fiber optic connectors and splices. This test must be performed on a lit optical fiber. The optical fiber may be carrying a signal or be illuminated using an optical test supply. Attach fiber identifier to one side of the optical connector/splice. Study and record the relative optical power. Repeat the measurement on the second side on the connector/splice. Take the difference involving the reading around the second side and the very first side. The distinction needs to be roughly equal for the optical attenuation on the optical connector/splice. The measurement is usually taken various occasions and averaged to improve accuracy. When the optical fiber identifier indicates high loss, the connector/slice may be defective.



Manufactures supplying fiber optic identifiers



You will get fiber optic identifiers from Wilcom, Perfect, 3M, Fitel, Noyes and many much more suppliers. We favor Wilcom and Fitel products because both manufacturers have extremely high consumer satisfaction rate.
