Fiber Coloring Machine – Fresh Light On A Relevant Point..

Why do you need Optical Fiber Coloring Machine and exactly what can it do for you If you have ever seen a telephone company technician working on the phone jump box outside your home, you ought to 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 correct wire, he connects the wire in your house.

During fiber optic network installation, maintenance, or restoration, it is additionally often necessary to identify a specific fiber without disrupting live service. This battery powered instrument looks like a long handheld bar and it is called fiber identifier or live fiber identifier.

How exactly does it work? There is a slot on the surface 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 and also the optical sensor detects it. The detector can detect both the actual existence of light and 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 strategy is so small, usually at 1dB level, that it doesn’t cause any trouble on the live traffic.

What kind of Fiber Drawing 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 to be able to support all these kinds of fibers and cables. While some other models are cleverly designed and they don’t must change the head adapter in any way. Some models only support single mode fibers and others supports both single mode and multimode fibers.

Precisely what is relative power measurement? Most high end fiber optic identifiers are equipped with a Liquid crystal display which could display the optical power detected. However, this power measurement cannot be utilized for a accurate absolute power measurement of 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 type of fiber optic cable. This relative power measurement has a lot of applications as described below.

Sample applications

1. Identification of fibers

The relative power reading can be used to aid in the identification of any live optical fiber.There are several tests that can be performed to isolate the preferred fiber cable from a team of fibers without taking along the link(s). Three methods that could be used include comparing relative power, inducing macrobends, and varying the optical power in the source. No single technique 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 may be used to identify high loss point(s) in a period of fiber. Through taking relative power measurements along a section of optical fiber which is suspected of having a very high loss point such as a fracture or tight bend, the alteration in relative power point out point could be noted. In case a sudden drop or increase in relative power between two points is noted, a very high loss point probably exists in between the two points. An individual are able to narrow in on the point by taking further measurements in 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 must be performed over a lit optical fiber. The optical fiber could be carrying a transmission or perhaps be illuminated utilizing an optical test source. Attach fiber identifier to 1 side of the optical connector/splice. Read and record the relative optical power. Repeat the measurement on the second side in the connector/splice. Consider the distinction between the reading on the second side and the first side. The main difference ought to be roughly similar to the optical attenuation in the optical connector/splice. The measurement may be taken many times and averaged to improve accuracy. When the optical fiber identifier indicates high loss, the connector/slice may be defective.

Fiber optic splice closure will be the equipment employed to offer room for fusion splicing optical fibers. Additionally, it provides protection for fused fiber joint point and fiber cables. You will find mainly 2 kinds of closures: vertical type and horizontal type. Quite a number of fiber splice closures are designed for different applications, including aerial, duct fiber cables and direct burial. In most cases, they may be usually used 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 often than vertical type (dome type) closures.

Most horizontal fiber closure can accommodate hundreds of Sheathing Line. They are created to be waterproof and dust proof. They could be found in temperature which range from -40°C to 85°C and can accommodate as much as 106 kpa pressure. The cases are usually 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 since the horizontal types. They are designed for buried applications.
