&”;Geeks talk about science and technology&”;, with a new perspective and new ideas, will accompany you to the magical world of science and technology. Thank you for inviting me. I don&;t know if it is because the performance of the light cat is not good or the light cat is damaged that it needs to be replaced, but we need to contact the staff. The performance of the optical cat can&;t be satisfied. If the user wants to replace it with a high-performance optical cat privately, he needs to contact the operator&;s maintenance personnel in advance to determine the model and specific operation of replacing the optical cat. If the optical cat is damaged or fails, it needs to be replaced, and it also needs to contact the operator&;s maintenance personnel for replacement. No matter what the replacement reason is, due to the working characteristics of the light cat, it is necessary to contact the operator&;s maintenance personnel in advance to deal with it. Introduction to the work of optical cat Many broadband users are not clear about the work of optical cat, and mistakenly think that they can restore the network by replacing the same wiring. In fact, this is not the case, which will lead to the unavailability of the network. At present, FTTH is mainly used in home wide network, which is called fttp. The operator&;s upper-end OLT equipment is connected with the optical cat equipment at the user end through optical fiber transmission, and the optical cat realizes data transmission of services such as network, voice and IPTV video. The optical cat can not communicate directly with the OLT equipment at the upper end, and it needs to bind the SN code of the optical cat at the OLT end to make relevant data to communicate. The result of replacing the optical cat casually is network interruption. Precautions for replacing optical cats for two different purposes 1. Self-replacement of optical cats caused by performance problems In fact, users are not advised to replace this equipment of optical cats themselves. The problem of short performance of optical cats can be solved by other better methods, and high-performance router equipment can be accessed. Optical cat only uses bridge mode to dial through the router. This can significantly improve network performance, reduce network delay, and enhance the coverage strength of wireless WiFi. If you want to replace the light cat yourself, you need to contact the operator&;s maintenance personnel to determine the brand and model of the light cat. s&; OLT equipment generally includes Fiberhome, Huawei, ZTE and other manufacturers. Different manufacturers have different GPON packaging protocols, so there will be problems of equipment incompatibility. It is best to buy the same brand and series of optical cat products. After purchasing the equipment, the operator&;s maintenance personnel are needed to assist in the binding of the optical cat with the upper OLT equipment, otherwise it will still be unusable. Note: Guangmao theoretically belongs to the operator&;s equipment. Users get the right to use it by paying a deposit (some cities are purchased by individual users). Once they buy new Guangmao equipment by themselves, they will completely lose the warranty of Guangmao. Second, the replacement of the optical cat caused by the damage or failure of the optical cat went on to say that because of the attribute of the optical cat, the operator has the obligation to upgrade, replace and maintain it free of charge. When the light cat is damaged or broken, it also needs to be replaced with the operator&;s maintenance personnel. As long as it is not man-made damage, replacing the new light cat is completely free. There is a problem that some users need to replace the optical cat to upgrade the bandwidth. For example, the original use of 100M optical cat and 100M network, to upgrade to 200M broadband, you need to upgrade to Gigabit optical cat here. It is also necessary to contact the operator&;s maintenance personnel for processing.Of course, the cost of a 100-megabit light cat is different from that of a gigabit light cat, and the deposit for a light cat may be improved to some extent. For users who quit the network, don&;t forget to return the optical cat to the operator and exchange it for the deposit of the optical cat. There are still some questions about replacing the light cat. Please leave a message to discuss and pay attention to it.
