Optical Fiber Ribbon Machine – Why Is This Important..

Why do you need Fiber Coloring Machine and 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 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 right 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 seems like an extended handheld bar and is also called fiber identifier or live fiber identifier.

How does it work? You will find a slot on the surface of a fiber optic identifier. The fiber under test is inserted into 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 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 strategy is so small, usually at 1dB level, that it doesn’t cause any trouble on the live traffic.

What sort of Optical Fiber Coloring Machine 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 must change a head adapter so that you can support all these types of fibers and cables. While many other models are cleverly designed plus they don’t have to alter the head adapter whatsoever. Some models only support single mode fibers yet others supports both single mode and multimode fibers.

What exactly is relative power measurement? Most high end fiber optic identifiers are equipped with a Liquid crystal display which may display the optical power detected. However, this power measurement cannot be utilized for a accurate absolute power measurement of the optical signal because 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 which have same type of fiber optic cable. This relative power measurement has many applications as described below.

Sample applications

1. Identification of fibers

The relative power reading could be used to assist in the identification of the live optical fiber.There are many tests which can be performed to isolate the required fiber cable from a group of fibers without taking along the link(s). Three methods that may be used include comparing relative power, inducing macrobends, and varying the optical power of the source. No single strategy is best or necessarily definitive. Using one or a mix of these techniques may be needed 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 suspected of getting a very high loss point such as a fracture or tight bend, the change in relative power indicate point could be noted. When a sudden drop or increase in relative power between two points is noted, a higher loss point probably exists between 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 must be performed on the lit optical fiber. The optical fiber can be carrying a signal or even 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 of the connector/splice. Go ahead and take difference between the reading on the second side and also the first side. The real difference needs to be roughly similar to the optical attenuation of the optical connector/splice. The measurement can be taken repeatedly and averaged to enhance accuracy. When the optical fiber identifier indicates high loss, the connector/slice might be defective.

Fiber optic splice closure will be the equipment utilized to offer room for fusion splicing optical fibers. Additionally, it provides protection for fused fiber joint point and fiber cables. There are mainly two kinds of closures: vertical type and horizontal type. Quite a number of fiber splice closures are designed for different applications, such as 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 two 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 may be mounted aerial, buried, or for underground applications. Horizontal types are used more frequently than vertical type (dome type) closures.

Most horizontal fiber closure can accommodate hundreds of Secondary Coating Line. They are designed to be waterproof and dirt proof. They may be used in temperature which range from -40°C to 85°C and can 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 also, they are called dome types. They meet the same specification since the horizontal types. They are designed for buried applications.
