Why do you need Fiber Coloring Machine and exactly what can it do for you If you have experienced a telephone company technician working on the phone jump box outside your house, you ought 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 for a tone. Once he finds the proper wire, he connects the wire in your house.
During fiber optic network installation, maintenance, or restoration, it is also often essential to identify a certain fiber without disrupting live service. This battery powered instrument appears like a lengthy handheld bar and is also called fiber identifier or live fiber identifier.
How exactly does it work? There exists a slot on the top of a fiber optic identifier. The fiber under test is inserted to the slot, then your fiber identifier performs a macro-bend on the fiber. The macro-bend makes some light leak right out of the fiber as well as the optical sensor detects it. The detector can detect both the existence of light as well as the direction of light.
A fiber optic identifier can detect “no signal”, “tone” or “traffic” plus it indicates the traffic direction.
The optical signal loss induced with this technique is so small, usually at 1dB level, that it doesn’t cause any trouble on the live traffic.
What kind of Optical Fiber Proof-Testing Machine will 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 change a head adapter so that you can support all these kinds of fibers and cables. While many other models are cleverly designed plus they don’t need to alter the head adapter whatsoever. Some models only support single mode fibers yet others can support both single mode and multimode fibers.
What exactly is relative power measurement? Most top end fiber optic identifiers come with a Liquid crystal display which may display the optical power detected. However, this power measurement cannot be used as a accurate absolute power measurement of the optical signal because of inconsistencies in fiber optic cables and the impact of user technique on the measurements.
But this power measurement could be used to compare power levels on different fiber links which have same form of fiber optic cable. This relative power measurement has a lot of applications as described below.
1. Identification of fibers
The relative power reading could be used to aid in the identification of any live optical fiber.There are several tests which can be performed to isolate the preferred fiber cable from a group of fibers without taking down the link(s). Three methods that could be used include comparing relative power, inducing macrobends, and varying the optical power of the source. No single method is best or necessarily definitive. Using one or a combination of these methods may be needed to isolate the fiber.
2. Identification of high loss points
Fiber optic identifier’s relative power measurement capability may be used to identify high loss point(s) in a length of fiber. By taking relative power measurements along an area of optical fiber that is certainly suspected of getting a high loss point like a fracture or tight bend, the modification in relative power indicate point could be noted. If a sudden drop or boost in relative power between two points is noted, a high loss point probably exists between the two points. An individual can then narrow in on the point through taking further measurements in between the two points.
3. Verify optical splices and connectors
Fiber optic identifier can be used to verify fiber optic connectors and splices. This test must be performed on the lit optical fiber. The optical fiber can be carrying a signal or perhaps be illuminated utilizing an optical test source. Attach fiber identifier to 1 side in the optical connector/splice. Read and record the relative optical power. Repeat the measurement on the second side from the connector/splice. Go ahead and take distinction between the reading on the second side and the first side. The real difference needs to be roughly comparable to the optical attenuation in the optical connector/splice. The measurement could be taken repeatedly and averaged to improve accuracy. If the optical fiber identifier indicates high loss, the connector/slice might be defective.
Fiber optic splice closure is definitely the equipment used to offer room for fusion splicing optical fibers. It also provides protection for fused fiber joint point and fiber cables. You will find mainly two kinds of closures: vertical type and horizontal type. Quite a number of fiber splice closures are equipped for different applications, like aerial, duct fiber cables and direct burial. In most cases, they are usually utilized in outdoor environment, even underwater.
Fiber Optic Splice Closure Types . For outside plant splice closure, there are 2 major types: horizontal type and vertical type.
1) Horizontal type – Horizontal type splice closures seem like flat or cylindrical case. They whzqqc space and protection for optical cable splicing and joint. They could be mounted aerial, buried, or for underground applications. Horizontal types are employed more often than vertical type (dome type) closures.
Most horizontal fiber closure can accommodate numerous SZ Stranding Line. They are created to be waterproof and dust proof. They may be utilized in temperature ranging from -40°C to 85°C and may accommodate up to 106 kpa pressure. The cases are often made of high tensile construction plastic.
2) Vertical Type – Vertical form of fiber optic splice closures looks like a dome, thus they are also called dome types. They satisfy the same specification because the horizontal types. They are equipped for buried applications.
