The construction methods of communication networks mainly include pipelines, aerial installation, and direct burial. Among these, core layer optical cables are primarily laid through pipelines, while distribution and trunk connections mainly use pipeline and aerial installation methods. Most service GYXTW optical cables are installed aerially. Currently, due to urban appearance and other reasons, many local governments prohibit the disorderly aerial installation of urban GYXTW optical cables and require the rectification of existing GYXTW optical cables into underground communication pipelines. This will make the shortage of pipeline resources even more apparent. After entering the optical communication era in the 1990s, domestic communication networks still used cement pipes suitable for copper cable layouts in urban communication pipeline construction. Around 2000, plastic pipes gradually began to be used in urban network construction across various regions.

First, large quantities of corrugated plastic pipes with an inner diameter of around 1000mm were widely used (before threading optical cables, several 32/28mm or 30/25mm plastic sub-ducts are threaded through the large pipe holes at once to improve pipe hole utilization). This led to the development of plastic grid pipes, 5-hole/7-hole梅花 plastic pipes, and silicone core pipes adapted for blow-in construction. After 2010, a high-utilization construction method emerged in several domestic cities, where multiple small-diameter micro-ducts were blown or pulled into 40/33mm silicone core pipes, and then micro-cables were blown into the micro-ducts. However, newly built communication pipelines still face challenges such as long construction cycles, high costs, and difficulties in obtaining municipal approvals. In the absence of pipeline resources, using technical means to construct communication network lines will be a highly practical and innovative approach.
