象无线频率一样,通信管道已被视为极其宝贵的资源,在通信行业飞速发展的今天,时分、频分、码分等先进技术被广泛地采用,那么就通信管道而言,能否采取更好的“管分技术”,回答是肯定的.我们的通信管道一般有灰管、PVC塑料管、HDPE波纹管等方式(特殊地段亦有采用钢管增加其机械强度),管道种类及管孔内径如表1所示: Like radio frequency, communication pipelines have been regarded as extremely valuable resources. With the rapid development of the communication industry, advanced technologies such as time division, frequency division and code division are widely adopted. So whether communication pipelines can adopt more Good “pipe technology”, the answer is yes.Our communication pipe generally gray pipe, PVC plastic pipe, HDPE bellows, etc. (special sections also use steel pipe to increase its mechanical strength), the type of pipe and pipe diameter As shown in Table 1:
