Why do you need Optical Fiber Ribbon Machine and 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 identify the incoming telephone wires by tapping onto the wires and listening for a tone. Once he finds the correct wire, he connects the wire into 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 long handheld bar and is also called fiber identifier or live fiber identifier.
How does it work? There exists a slot on the surface 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 of the fiber as well as the optical sensor detects it. The detector can detect both the presence of light as well as 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 strategy is so small, usually at 1dB level, it doesn’t cause any trouble on the live traffic.
What type of Optical Fiber Ribbon Machine can 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 change a head adapter in order to support all these types of 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 yet others supports both single mode and multimode fibers.
Precisely what is relative power measurement? Most high end fiber optic identifiers include a Liquid crystal display which can display the optical power detected. However, this power measurement cannot be utilized for a accurate absolute power measurement in the optical signal as a result of inconsistencies in fiber optic cables as well as the impact of user technique on the measurements.
But this power measurement can be used to compare power levels on different fiber links that have same kind of fiber optic cable. This relative power measurement has many applications as described below.
1. Identification of fibers
The relative power reading may be used to aid in the identification of a live optical fiber.There are numerous tests that may be performed to isolate the required fiber cable from a team of fibers without taking on the link(s). Three methods that might be used include comparing relative power, inducing macrobends, and varying the optical power from the source. No single method is best or necessarily definitive. Using one or a mixture of these methods may be required to isolate the fiber.
2. Identification of high loss points
Fiber optic identifier’s relative power measurement capability can be used to identify high loss point(s) in a duration of fiber. If you take relative power measurements along an area of optical fiber which is suspected of obtaining a high loss point like a fracture or tight bend, the change in relative power point out point can be noted. When a sudden drop or rise in relative power between two points is noted, a higher loss point probably exists involving the two points. The user can then narrow in on the point through taking further measurements between the two points.
3. Verify optical splices and connectors
Fiber optic identifier may be used to verify fiber optic connectors and splices. This test has to be performed on a lit optical fiber. The optical fiber may be carrying a signal or even be illuminated employing an optical test source. Attach fiber identifier to a single side in the optical connector/splice. Read and record the relative optical power. Repeat the measurement on the second side in the connector/splice. Take the distinction between the reading on the second side and also the first side. The real difference ought to be roughly comparable to the optical attenuation from the optical connector/splice. The measurement can be taken repeatedly and averaged to boost accuracy. If the optical fiber identifier indicates high loss, the connector/slice could be defective.
Fiber optic splice closure will be 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. A large collection of fiber splice closures are equipped for different applications, such as aerial, duct fiber cables and direct burial. In most cases, they are usually used 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 underground applications. Horizontal types are employed more often than vertical type (dome type) closures.
Most horizontal fiber closure can accommodate countless FTTH Cable Production Line. They are created to be waterproof and dust proof. They can be used in temperature starting from -40°C to 85°C and will accommodate approximately 106 kpa pressure. The cases are usually manufactured from high tensile construction plastic.
2) Vertical Type – Vertical kind of fiber optic splice closures looks like a dome, thus also, they are called dome types. They meet the same specification since the horizontal types. They are designed for buried applications.
