Today, in the Internet age, people are embracing the faster Internet and greater bandwidth and fiber, and fiber has become a bigger achievement than wired and DSL technologies. With the growing appeal for a faster, more durable Internet, broadband fiber broadband bundling includes 700 Mbps, and advances in improving its capabilities are still evolving. In 2014, the right of abode on new technologies enabled optical fiber to transmit information at speeds up to 21 times its recognized capacity. Fiber optic splice closure is an important accessory in the optical handbook system and is mainly used for fiber optic connection of optical cable terminals, installation of optical fiber adapters, dimming of optical cables, and then balancing of optical fibers. It is recommended to configure balanced batteries and protective covers for optical cables. The operation and adaptability in use plays an important role. In the past, fiber-optic buildings for light advice were typically centered around some 100 or fewer consoles aggregated into consoles of several converged fiber optic equipment. Others took the initiative to reduce battery capacity, deploy maneuvering, and below Simple structure and other disadvantages. Historically, closures for fiber optic networks have been a bulky, over-designed structure that is expensive and complicated to install and re-enter. They are usually installed and serviced by an elite team of telephone companies that are separate from the copper service staff. As the fiber goes further into the loop, the division of responsibilities and expertise becomes impractical and expensive. Fiber optic splice closure must protect exposed fibers and connectors from the environment and protect the fiber from damage during processing. Carefully designed pallets and fiber optic cabling help to make the fiber easy to manage, which is critical to the success and reliability of fiber optic installations. Two types of trays are required: transfer tray and splice tray. A transition tray is required between the cable jacket opening and the splice tray to detach the fiber in a controlled manner and store the excess fiber. As fiber usage increases, special consideration needs to be given to managing a large number of closed fibers. In mixed fiber / coax (hfc) systems, there are many cases where a small amount of fiber can be dropped from a ribbon cable containing up to 432 fibers.
