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 recognize 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 additionally often necessary 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 does it work? There is a slot on the top of a fiber optic identifier. The fiber under test is inserted in to the slot, then your fiber identifier performs a macro-bend on the fiber. The macro-bend makes some light leak out from the fiber as well as the optical sensor detects it. The detector can detect both the presence of light and also 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 from this technique is so small, usually at 1dB level, which it doesn’t cause any trouble on the live traffic.
What sort of SZ Stranding Line 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 change a head adapter to be able to support all most of these fibers and cables. While many other models are cleverly designed and they also don’t must change the head adapter at all. Some models only support single mode fibers as well as others supports both single mode and multimode fibers.
What 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 utilized as a accurate absolute power measurement in the optical signal due to inconsistencies in fiber optic cables as well as the impact of user technique on the measurements.
But this power measurement may be used to compare power levels on different fiber links that have same kind of fiber optic cable. This relative power measurement provides extensive applications as described below.
1. Identification of fibers
The relative power reading could be used to assist in the identification of any live optical fiber.There are numerous tests that may be performed to isolate the required fiber cable from a team of fibers without taking down the link(s). Three methods that might be used include comparing relative power, inducing macrobends, and varying the optical power in the source. No single method is best or necessarily definitive. Using one or a mix of these techniques may be required to isolate the fiber.
2. Identification of high loss points
Fiber optic identifier’s relative power measurement capability could be used to identify high loss point(s) in a period of fiber. By taking relative power measurements along an area of optical fiber that is certainly suspected of obtaining a very high loss point for instance a fracture or tight bend, the alteration in relative power point to point could be noted. When a sudden drop or rise in relative power between two points is noted, a high loss point probably exists involving the two points. The user are able to narrow in on the point if you take further measurements in between the two points.
3. Verify optical splices and connectors
Fiber optic identifier could 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 using an optical test source. Attach fiber identifier to one side from 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 difference between the reading on the second side as well as the first side. The real difference ought to be roughly equal to the optical attenuation from the optical connector/splice. The measurement could be taken several times and averaged to enhance accuracy. If the optical fiber identifier indicates high loss, the connector/slice may be defective.
Fiber optic splice closure will be the equipment used to offer room for fusion splicing optical fibers. Additionally, it provides protection for fused fiber joint point and fiber cables. You can find mainly two kinds of closures: vertical type and horizontal type. A large collection of fiber splice closures are equipped for different applications, including aerial, duct fiber cables and direct burial. Generally speaking, they may be usually found in outdoor environment, even underwater.
Fiber Optic Splice Closure Types . For outside plant splice closure, the two main major types: horizontal type and vertical type.
1) Horizontal type – Horizontal type splice closures appear to be flat or cylindrical case. They whzqqc space and protection for optical cable splicing and joint. They can be mounted aerial, buried, or for underground applications. Horizontal types are employed more frequently than vertical type (dome type) closures.
Most horizontal fiber closure can accommodate countless Optical Fiber Coloring Machine. They are created to be waterproof and dust proof. They could be found in temperature ranging from -40°C to 85°C and may accommodate up to 106 kpa pressure. The cases are often manufactured from high tensile construction plastic.
2) Vertical Type – Vertical type of fiber optic splice closures looks like a dome, thus they are also called dome types. They meet the same specification as the horizontal types. They are designed for buried applications.
