Why do you need Optical 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 home, you should have noticed a special handheld phone like instrument. The technician uses it to distinguish the incoming telephone wires by tapping onto the wires and listening for a tone. Once he finds the proper wire, he connects the wire into your house.
During fiber optic network installation, maintenance, or restoration, it is also often necessary to identify a particular fiber without disrupting live service. This battery powered instrument looks like a lengthy handheld bar and is also called fiber identifier or live fiber identifier.
So how exactly does it work? There exists a slot on the top of a fiber optic identifier. The fiber under test is inserted into the slot, then the fiber identifier performs a macro-bend on the fiber. The macro-bend makes some light leak right out of the fiber and the optical sensor detects it. The detector can detect both the presence of light and 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 with this method is so small, usually at 1dB level, which it doesn’t cause any trouble on the live traffic.
What kind of Sheathing 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 so that you can support all most of these fibers and cables. While many other models are cleverly designed and they also don’t must modify the head adapter whatsoever. Some models only support single mode fibers as well as others can support both single mode and multimode fibers.
Precisely what is relative power measurement? Most top quality fiber optic identifiers come with a Liquid crystal display which could 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 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 may be used to assist in the identification of the live optical fiber.There are numerous tests that may be performed to isolate the required fiber cable from a small group of fibers without taking down the link(s). Three methods that may be used include comparing relative power, inducing macrobends, and varying the optical power in the source. No single strategy is best or necessarily definitive. Using one or a combination 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 length of fiber. By taking relative power measurements along a section of optical fiber that is certainly suspected of having a very high loss point for instance a fracture or tight bend, the modification in relative power point to point could be noted. When a sudden drop or rise in relative power between two points is noted, a higher loss point probably exists between the two points. An individual are able to narrow in on the point if you take further measurements involving 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 may 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 comparable to the optical attenuation in 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 might be defective.
Fiber optic splice closure is the equipment employed to offer room for fusion splicing optical fibers. It also provides protection for fused fiber joint point and fiber cables. You will find mainly 2 kinds of closures: vertical type and horizontal type. A large collection of fiber splice closures are designed for different applications, such as aerial, duct fiber cables and direct burial. Generally speaking, they may be 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 look 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 utilized more frequently than vertical type (dome type) closures.
Most horizontal fiber closure can accommodate numerous Optical Fiber Ribbon Machine. They are designed to be waterproof and dirt proof. They could be utilized in temperature which range from -40°C to 85°C and can accommodate up to 106 kpa pressure. The cases are usually manufactured from high tensile construction plastic.
2) Vertical Type – Vertical kind of fiber optic splice closures seems like a dome, thus they are also called dome types. They fulfill the same specification since the horizontal types. They are equipped for buried applications.
