HFF stands for "Hybrid Fiber Coaxial", which is hybrid fiber optic coaxial cable. This is a network technology used to deliver a variety of services to homes, consisting of a combination of fiber optic and coaxial cables. The main advantage of HFF is that it can transmit signals over almost any distance range, including long, medium and short distance transmission. In addition, it is capable of handling large amounts of data, can transmit a variety of high-definition signals, such as video and music, and allows customers to transmit multiple types of signals individually or together. At the same time, HFF can also help save money, because using this technology usually costs less than using fiber alone.
Three-in-one surface mount (often called three-in-one surface mount) is a packaging method in LED display technology. It refers to the synthesis of three light-emitting points of red, green and blue encapsulated in the same light-emitting tube. Since these three light-emitting points are packaged in the same light-emitting tube, when viewed from a close distance, they appear as a point rather than a line. This packaging method can improve production efficiency and display effects because it reduces the number and complexity of components, while also enhancing the color expression and clarity of the display.
In general, HFF and three-in-one surface mount are two completely different technologies, which are used in different fields and scenarios.
