The National Day holiday has just passed, and the magnificent scene of the National Day parade is still vividly remembered. The sound at the celebration site is also heart stirring, presenting such a "good voice" that cannot be separated from the powerful sound support system.

A total of 520 sets of mobile speakers were installed throughout the military parade, with nearly 500 staff members operating these mobile speakers for sound collection, processing, and amplification transmission.

This military parade has a wide range of activities and a large number of participants, which have no reference in the world. Therefore, in order to meet the requirements of the celebration's sound, a sound support command center was specially established. However, despite this, the technical requirements for dealing with such a large celebration are still extremely high.

For example, the renovation of hardware facilities is very troublesome. In order to meet the requirements of the celebration, the entire command center launched a comprehensive renovation of all cables on Chang'an Street in front of Tiananmen Square. The length of fixed cables laid for renovation reached 460 kilometers, and the length of mobile cables reached 100 kilometers. The amount of work is not insignificant.

In addition to the establishment of the sound support command center, there are also 64 base stations responsible for transmitting signals throughout the National Day celebration. Nearly 60 mixing consoles have been put into use, and each person's operation is related to the effectiveness of the entire celebration.

According to relevant staff, the use of optical cables has become very common in this 79th anniversary celebration. Compared to ten years ago in the 60th anniversary celebration, the use of optical cables is still very rare. It can be seen that the changes in the past decade are the progress of technological equipment and equipment settings.

The bandwidth of fiber optic networks can support more information collection points, information stations, and the mutual transmission and exchange of information, playing a significant role in better completing audio support tasks. For example, according to different sound pickup requirements, the square is equipped with many regional mixing stations at different points. The signal source passes through the sound amplification room for tuning, and after corresponding delay, the relevant areas are then amplified. This greatly improves the uniformity of the sound felt by the audience in the entire sound field.

Whether it is the renovation of cables or the widespread use of optical cables, it can be seen that the development of cable technology supports the smooth implementation of the National Day celebration. With the comprehensive development of 5G and technological progress in the future, the demand for cables will also increase. Henan Shenghua Cable, as a part of China's cable industry, will also contribute its own strength to the development of cable technology.
