How long does it take to learn optical fiber fusion technology?

Question 1: To what extent should optical fiber welding be practiced to be a master? Make a 12 core connector in 20 minutes, which is the energy connection just mentioned. Mastery is what any optical cable and various connections can do, and it can be called mastery. Generally speaking, a skilled worker who can read and pick up drawings.

Question 2: How long does it take to learn optical fiber fusion technology? It takes 1 hour. How many times do you operate it yourself?

Question 3: Where can I learn the optical fiber fusion technology? Thank you? Optical fiber fusion technology: when light is transmitted in optical fiber, it will produce loss, which is mainly composed of transmission loss of optical fiber itself and fusion loss at optical fiber joint. Once the optical cable is ordered, the transmission loss of the optical fiber itself is basically determined, and the welding loss at the optical fiber joint is related to the optical fiber itself and the field construction. Efforts to reduce the welding loss at the optical fiber joint can increase the transmission distance of optical fiber relay amplification and improve the attenuation margin of optical fiber link.

Question 4: Is there a future in learning the communication industry? I think the future work of optical fiber fusion is certainly promising, dear. Now the three major e-commerce companies are speeding up.

We will also reduce the internet fee in the future.

Of course, the internet fee can't really drop, but the traffic is used more and more.

It definitely needs a lot of optical fiber welding work, and I think it is quite promising.

I bought Elok's welding machine last month.

Now I'm in this business, too.

Question 5: Where can I learn the optical fiber fusion technology? Find any company that can solder for a few days.

Question 6: What title can I get after working in optical fiber and cable welding technology for several years? Cable welding is the skill of line workers, just like making fish-flavored shredded pork is one of the skills of chefs. No one can cook fish-flavored shredded pork well, so give him a chef title.

Question 7: There are many factors affecting the fusion loss of optical fiber, which can be roughly divided into internal factors and external factors of optical fiber. 1. The intrinsic factor of optical fiber refers to the factor of optical fiber itself, which mainly includes four points. (1) fiber mode field diameters are inconsistent; (2) The core diameters of the two optical fibers are not matched; (3) The cross section of the fiber core is not circular; (4) The concentricity of core and cladding is not good. Among them, the inconsistency of fiber mode field diameter has the greatest influence. According to CCITT's suggestion, the tolerance standard of single-mode fiber is as follows: mode field diameter: (9 ~ 10μ m) 10%, that is, the tolerance is about1μ m; Cladding diameter:1253μ m; The concentricity error of mode field is ≤6%, and the noncircularity of cladding is ≤2%. 2. The external factor that affects the splicing loss of optical fiber is splicing technology. (1) Axis misalignment: The core of single-mode optical fiber is very thin, and the axis misalignment of two butted optical fibers will affect the connection loss. When the misalignment is 1.2μm, the connection loss reaches 0.5 db(2) axis inclination; when the fiber section is inclined10, the splicing loss is about 0.6dB; if the splicing loss is required to be ≤0. 1dB, the inclination angle of single-mode fiber should be ≤ 0.3. (3) End-face separation: Poor connection of movable connectors will easily lead to end-face separation and greater connection loss. When the discharge voltage of the welding machine is low, it is easy to produce end-face separation, which can be found in the welding machine with tension test function. (4) End face quality: When the flatness of the end face of the optical fiber is poor, there will be loss or even bubbles. (5) Physical deformation of the optical fiber near the splice point: tensile deformation of the optical fiber during erection, excessive clamping pressure of the optical fiber in the splice box, etc. , will have an impact on splicing loss, and even repeated welding can not improve it. 3. The influence of other factors. The operation level of the joiner, the operation steps, the process level of winding fibers, the cleanliness of the internal electrode of the welder, the setting of welding parameters and the cleanliness of the working environment will all affect the welding loss value. 1. Try to use the same batch of high-quality brand-name bare fiber on one line. For the same batch of optical fibers, the mode field diameters are basically the same. After the fiber is disconnected at a certain point, the mode field diameters at both ends can be regarded as the same, so splicing at this disconnection point can minimize the influence of the mode field diameter on the fiber welding loss. Therefore, the optical cable manufacturers are required to use the same batch of bare optical fibers for continuous production according to the required optical cable length, and number each plate in sequence to distinguish between the A end and the B end, and the phenomenon of jump connection is not allowed. When laying optical cables, they must be laid in a certain routing sequence according to the number, and ensure that the B end of the front cable is connected with the A end of the rear cable, so as to ensure that the optical cable can be welded at the disconnection point and minimize the welding loss. 2. The erection of optical cable shall be carried out as required. In the construction of optical cable laying, it is forbidden to make small circles, fold or twist the optical cable. 3km optical cable must be constructed by more than 80 people, and 4km optical cable must be constructed by more than 100 people, and equipped with 6 ~ 8 walkie-talkies; In addition, the cable laying mode of "following the shoulder of the optical cable" can effectively prevent the occurrence of back-off. Traction force shall not exceed 80% allowed by optical cable, and instantaneous maximum traction force shall not exceed 100%. Traction should be added to the reinforced layer of the optical cable. The laying of optical cables should be strictly in accordance with the requirements of optical cable construction, so as to minimize the probability of optical fiber damage in optical cable construction and avoid increasing the welding loss due to the damage of optical fiber core. 3. Choose experienced and trained optical fiber splicing personnel for splicing, most of which are automatically spliced by splicing machines, but the level of splicing personnel directly affects the splicing loss. The splicing personnel should strictly follow the optical fiber splicing process flow chart and use OTDR to test the splicing loss of the fusion point at the same time of fusion. Do not meet the requirements should be re-welded. For points with large welding loss, it is advisable to repeat welding for 3 ~ 4 times. When the welding loss of multiple optical fibers is large, a section of optical fiber can be cut off and welded again. 4. Connecting optical cables should be carried out in a clean environment. It is forbidden to operate in the open air in dusty and humid environment. The connecting parts, tools and materials of optical cable shall be kept clean, and the optical fiber connector shall not be affected with moisture. The optical fiber to be cut must be clean and free of dust. After cutting, the optical fiber should not be exposed to air for too long, especially in dusty and humid environment. 5. Choosing high-precision fiber end milling cutter to prepare fiber end face directly affects welding loss. The cut optical fiber should be a plane mirror without burrs and defects. The inclination angle of the fiber end axis should be less than 65438 0 degrees. The invention can not only improve the success rate of optical fiber cutting, but also improve the quality of optical fiber end face. This is especially important for the fusion point that OTDR can't test (that is, the blind spot of OTDR test) and the maintenance and repair of optical fiber. 6. Correct use of welding machine The function of welding machine is to put two ... >; & gt

Question 8: Is it tiring to operate the optical fiber fusion technology? First of all, you need to have a fusion machine and carry it with you. Work is not easy, I can climb stairs, and sometimes I have to go to my client's house to melt.

When I was in fused fiber, I expected to fail many times from the beginning. Just practice more. As far as this operation is concerned, it is very easy to learn.

Question 9: Optical fiber fusion technology makes money. Hello, disrespectful users, there is a big market.

All operators are promoting FTTH (fttp) network construction in an all-round way, and optical fiber hot-melt technology is favored by all operators because of its few faults and long service life.

However, most major operators implement provincial-level unified bidding and procurement, and it is difficult for new enterprises to be shortlisted.
