Our network communication now relies more and more on optical cables. Of course, there are more steps and precautions for the successful cutover of optical cables. Of course, there are many things to pay attention to in this work, such as optical cable connection. Strictly follow the designed chromatographic sequence and the corresponding direction of the fiber core for connection, etc. Let's take a look at the steps and precautions for successful optical cable cutover.
Detailed steps for fiber optic cable cutover
1. Before the fiber optic cable is cut, it is necessary to check whether the connector position of the fiber optic cable cut and whether the fiber core conforms to the design. This work should be done when reviewing the routing. Since there may be many optical cables under the tube well, the connector of the tube well at the cutover may not be the one used in this project. Therefore, you must be careful when reviewing the route, and determine the number of the main cable at the cutover and the design of the main cable at the end of the computer room. Whether it is consistent or not, so as to determine whether the joint position of the optical cable cutover in the design is accurate, the feasibility report before the optical cable cutover must be done.
2. The preparation work for optical cable cutover, because the optical cable cutover is limited by time, the quality of the preparation work often affects the cutover time, and the tools and materials need to be complete. The staff must enter the site at least one hour in advance, put on the splice box and open it, and determine the pre-cut work such as cutting the core of the trunk cable, stripping and fixing the access optical cable.
3. In terms of optical cable connection, the optical cable must be connected in strict accordance with the designed chromatographic sequence and the corresponding direction of the fiber core.
4. Test work, the test work is divided into pre-cutting test and post-cutover test. When the cutover preparation work is done at the cutover site, personnel must be arranged to test the end of the cutover. The purpose of the pre-cutover test is to reconfirm the trunk with the cutover site. Whether the cut fiber core of the optical cable is accurate, only when both ends are confirmed to be correct, the fiber core to be cut can be disconnected. After the fiber is cut, it is necessary to test whether the fiber core that may be affected is normal, so as to avoid operation errors. And lead to greater consequences; after the cutover test, pay attention to whether the core corresponds to the core and whether the core routing is accurate, the joint loss, line attenuation, etc. must meet the design requirements and make a record.
5. In terms of on-site cleaning, after the cutover of the project is completed, the site must be cleaned up, so as not to affect the city appearance, road cleaning and other issues, so as to avoid affecting the company's image.
Precautions for fiber optic cable cutover
1. The length of the new and original cables should be sufficient, leaving enough margin for possible repeated operations.
2. Check the pipe numbers of the two cutover points of the new cable to avoid the appearance of new mandarin duck pipes and mark them.
3. After the original cable is opened, the two cutover points should check the fiber numbers one by one with the station in the same direction. The method is to use a tube cutter to open two or three ports at the place where the tube needs to be identified and does not affect the cutover. Because the optical fiber has redundancy, a certain length of optical fiber is exposed. Use alcohol to remove the ointment, and use thinner objects. (Toothpicks, cable ties, etc.), pick up the optical fibers one by one for micro-bending, check with the equipment room, and then compare with the fiber core comparison table on the cutover plan, and correct it according to the order of the fibers in the equipment room. This method is to "make the wrong mistake" if there is a wrong fiber phenomenon, which can avoid pinching the wrong fiber, and the order of the equipment room does not need to be changed. Just save the data for later use.
4. After each tube of fiber optic splicing is completed, it must be monitored in real time to ensure the quality of the splicing, and to avoid the trouble of making the fiber optic disk after installation. After the splice box is sealed and installed, it should be checked again to avoid fiber breakage during installation.
5. You must wait patiently for the circuit to recover, and evacuate after the transmission, network management, users, etc. have confirmed that there is no error.
6. Because the cutover is mostly at night and the light is not good, you must carefully count the items to avoid loss, and pay attention to safety in the complex terrain.
The steps and precautions for the successful cutover of the optical cable need to be firmly remembered by everyone. Another point to note is that after the cutover is completed, we also need to take some simple protection measures for the optical cable at the joint point.
