贵阳市处于群山包围之中,具有海拔高,纬度低的特点,地形对高速公路线路的影响非常大,还由于历史原因,将贵阳东、西出口高速公路分割为独立的两段路,成为典型的复杂路段,其通讯系统设计非常繁琐。文章依据高效营运、节约投资的原则,将两段路通讯系统进行合并设计,通过征借其他路段的光纤组建了通讯接入网环网。尽管各通讯站之间物理距离过长,但对光信号设计要求并没有降低,取得了便利性与经济性的双赢。
Guiyang City, surrounded by mountains, with high altitude, low latitude characteristics, the terrain on the highway line is very large, but also due to historical reasons, the Guiyang East and West exit expressway into two separate sections, becoming Typical complex sections, the communication system design is very cumbersome. Based on the principle of efficient operation and economical investment, the article combines the design of the two sections of communication system and sets up the communication access network ring network by borrowing the optical fibers of other sections. Although the physical distance between communication stations is too long, the design requirements for optical signals have not been reduced and a win-win situation has been achieved with convenience and economy.
