FTTh construction is to connect optical fiber directly to the user's home to provide users with high-speed and stable broadband access services. In the FTTH construction process, a variety of materials and equipment are needed.

Optical fiber is a communication medium used for transmitting optical signals. It is usually made of glass or plastic and transmits light pulses through the principle of reflection, enabling efficient data transmission. The core of fiber optic transmission technology is to utilize the principle of light reflection, by using two layers of materials with different refractive indices inside and outside the fiber optic, to ensure that the optical signal does not scatter, thereby maintaining signal quality over extremely long distances.

In the 1970s, it was determined that if optical transmission could achieve less than 20 dB/km, this solution could replace copper wire in the telecommunications market. And it did! Today, optical fiber has dethroned copper wire for its transmission performance, but it has also far surpassed the potential expansion of telecommunications networks.

This pre-connected fiber distribution box is born for this purpose - it is an advanced network node device with high integration and excellent performance, which can greatly simplify the installation process and maintain long-term stable operation in various harsh environments.
