Is there a market for optical fiber fusion splicing technology?

Of course there is!! Weak current system integration Safe City Monitoring System Integrated wiring.

In the field of communication (mobile, Unicom, telecom), cable repair requires optical fiber fusion technicians and equipment. Of course, in a city generally (mobile, Unicom, telecommunications, radio and television units are the most advanced fusion splicers and equipment) but far from meeting the market demand.

For example, I am engaged in a security weak current project in Zhenjiang, Jiangsu Province in January 2010.

I did a security project, the backbone is all optical cables, and optical fiber splicing should be carried out before the equipment, and our company was discharged to Inner Mongolia in the fusion splicer, which will take 2 weeks.

to end. I can't wait!! I had to find the local network communication engineering team in Zhenjiang (there was an introducer), but ** was still quite high. I didn't say yes!! Later, a colleague's friend came from Shanghai!! Help me splice all the cables.

Finish. As you can see from this example!! As long as there is a device like this and the technology is mastered, the rest is the industry promotion.

This is the most basic skill for you to learn optical transmission, just the use of an instrument, there are still a lot of things to learn in optical transmission, and you will have a future if you learn the optical transceiver thoroughly.

The market is good, and I'm doing that, but there's no engineering.

Technology, I learned it in half a day, how big do you think the market is.

The materials required for optical fiber splicing are:

Fiber stripping pliers, cutters, fusion splicers, heat shrinkable sleeves, alcohol swabs and other necessary operating equipment, tools and necessary materials.

Fusion splicing steps for optical fibers:

The fusion splicing fiber should be equipped with fusion splicing equipment with appropriate battery capacity and precision according to the requirements of the optical cable project, that is, the fusion splicer.

Before splicing, according to the material and type of optical fiber, the key parameters such as the optimal pre-melting main fusion current and time, as well as the amount of optical fiber feeding, are set on the fusion splicer.

During the welding process, the "V" groove, electrode, objective lens, and welding chamber of the welding machine should be cleaned in time, and the welding should be observed at any time for bubbles, too fine, too coarse, false melting, separation and other undesirable phenomena in the welding, pay attention to the tracking and monitoring results of the OTDR test instrument, analyze the causes of the above undesirable phenomena in time, and take corresponding improvement measures. If there is a false melt phenomenon for many times, check whether the materials and models of the two optical fibers are matched, whether the cutter and the fusion splicer are polluted by dust, and check the oxidation status of the electrode.

After ensuring that there is no problem with the quality of optical fiber splicing, the heat shrinkable loose sleeve protects the optical cable at the fusion splicing point, and is properly placed and stored in order.

Let's tell you this, the complete optical fiber fusion tutorial on Youku Take a look at it, there is an introduction to what is needed in it, what is a peeling knife 6s alcohol canister... It's not a lot, and it's not enough to have a machine anyway.

The two optical fibers that need to be spliced are stripped until only the glass filament remains, and then cut with a special cutter, and then welded with an optical fiber fusion splicer, and placed in a special fusion splice package after splicing.

Only the optical fiber fusion splice sleeve is required, and other fusion splicer accessories are available. Then there is the sheath or junction box after the welding is completed.

Weak current engineering: the detailed steps of optical fiber splicing.

If you need a crystal head, you can go to the Wujiaohua store to buy it!

1. Optical fiber splicing is a meticulous work, especially in the end face preparation, splicing, fiber coil and other links, which requires the operator to observe carefully, consider carefully, and operate in a standardized manner.

2. When two optical cables are connected, the optical fibers in the optical cable should be docked, because the optical fibers are like glass filaments, and the docking requires special optical fiber fusion tools.

3. Optical fiber splicing in Anhui can choose the "starlight network" of Buruiqi on Feixi Road.

Hope it helps.

The concept of optical fiber melting can be understood according to the continuation of the wire, the wire is metal, as long as the metal contact can be conductive, so when the telecommunication is connected, it is usually the two ends of the metal wire wound together on it, but the optical fiber is to transmit the optical signal, the transmission of the optical signal depends on the reflection inside the optical fiber, if the optical fiber is broken, you can't wrap the two ends like the wire, you must re-melt the two ends on the special joint, and then the joint is stuck together, so that the optical signal can pass through. The reason why the word melting is used is largely because the material of optical fiber is glass, resin and plastic, and all have a characteristic, that is, it can be melted after heating, so the splicing of light can also be called splicing, which is the splicing after melting.

It's all in one toolbox.

1.Cable cutter.

2.Wire strippers.

3.Cuttering knife.

4.Alcohol. 5.Hot overnight casing.

These are the only things that are necessary, and the rest depends on the specific situation.

Optical fibers are a type of optical waveguide, so there is also a pattern problem with the propagation of light waves within it. The mode refers to the structural pattern of the electromagnetic field of the cross-section and longitudinal section of the transmission line, that is, the distribution of electromagnetic waves. In general, different modes have different field structures, and each transmission line has a corresponding fundamental mode or major mode.

The fundamental mode is the mode with the longest cut-off wavelength. In addition to the fundamental mode, other modes with a shorter cut-off wavelength are called higher-order modes. According to the number of modes that optical fiber can transmit, it can be divided into single-mode fiber and multi-mode fiber.

As for the interface type, you are talking about the pigtail interface, which is commonly known as a square head and a round head, and different shapes of joints contain various types of different sizes and functions. The details are as follows:

In the labels that indicate pigtail joints, we often see signs such as "FC PC" and "SC PC".

"The front part indicates the connector model of the pigtail.

The "SC" joint is a standard square joint, made of engineering plastics, which has the advantages of high temperature resistance and not easy to oxidize. The optical interface on the side of the transmission equipment generally uses SC connectors.

The LC connector is similar in shape to the SC connector and is smaller than the SC joint.

The "FC" connector is a metal connector, which is generally used on the ODF side, and the metal connector can be plugged and unplugged more times than the plastic one.

The latter indicates the cross-sectional process of the fiber optic joint, that is, the grinding method.

"PCs" are most widely used in telecom operators' equipment, where the connector cross-section is flat.

The attenuation of "UPC" is smaller than that of "PC", which is generally used for equipment with special needs, and some foreign manufacturers use FC UPC for internal skipping fiber in ODF racks, mainly to improve the indicators of ODF equipment itself.

Simple welding only requires a hot melt machine, heat shrinkable protective tube, alcohol, medical cotton, and protective box.

Cutting knives, Miller pliers, peeling pliers, heat shrink tubing, protective sleeves, alcohol swabs are required.

Fusion splicer, pigtail, coupler, fiber box, hehehe!

The splicing process of the optical cable (the picture below shows the optical fiber fusion splicer):

The first step is to strip the cable and secure it into the splice box. When fixing multi-bundle tube layer optical cables, due to the layered coil fiber, each bundle tube should be placed in sequence to avoid entanglement. Thread the optical cable into the splice box, and be sure to press it tightly when fixing the wire, and there can be no loosening.

In the second step, the fiber is passed through the heat shrink tubing. Separate the fibers of different bundles and colors and pass them through the heat shrink tubing. Fiber optic cables that have been stripped of the coating layer are fragile, and heat shrink tubing can be used to protect fiber optic connectors.

The third step is to turn on the power supply of the fusion splicer and select the appropriate welding method. There are two kinds of power supply of fusion splicer: DC and AC, which should be switched and switched reasonably according to the type of power supply current.

The fourth step is to make the optical fiber endface. The quality of the optical fiber endface will directly affect the quality of the splicing, so it is necessary to make a qualified endface before splicing.

The fifth step is to clean the bare fiber to tear the cotton into small pieces with a flat surface, stick a little alcohol, clamp the stripped optical fiber, wipe along the optical fiber axial, use moderate force, and use different parts and layers of cotton each time, so as to improve the utilization rate of cotton.

The sixth step, the cutting of bare fiber, first clean the cutter and adjust the position of the cutter, the placement of the cutter should be stable, when cutting, the action should be natural, smooth, not heavy, not light. Avoid the occurrence of undesirable end faces such as fiber breakage, bevel angle, burr and crack.

There are special optical fiber fusion splicing machines

Talent for fusion splicing fibers can be found by:

It should be noted that the talent market for spliced optical fiber is large, but it is necessary to contact truly experienced talents through formal channels. At the same time, it is also necessary to pay attention to prevent false recruitment information and choose formal recruitment platforms and institutions to avoid unnecessary losses.
