光缆敷设按敷设方式不同，光缆可分为管道光缆、直埋光缆、架空光缆和水底光缆。按缆芯结构的不同，光缆可分为层绞式光缆、骨架式光缆、中心束管式光缆和带状式光缆

直埋光缆敷设步骤：(1)光缆沟的开挖及要求：光缆直埋敷设时，可能会受到诸多因素的影响，如耕地、排水沟和其他地面设施、鼠害、冻土层深度等。因此，直埋光缆一般要比管道光缆埋得深。只有达到足够的深度以后，才能防止各种外来的机械损伤。此外，在达到一定深度后地温较稳定，减少了温度变化对光缆性能和光纤传输特性的影响，减小了鼠害，从而保证了光缆线路的安全性和通信传输质量。(2)光缆沟的深度应符合设计要求。原邮电部规定：一般情况下光缆沟的深度为1.2m，上宽为60cm，底为30cm。当同沟敷设两条或两条以上的光缆时，每增加一条光缆，沟宽增加10cm。(3)光缆沟的沟底应平整、无坎。在石质、半石质沟底应垫10cm细土或砂土，以免伤害光缆。(4)光缆沟应平直，与中心线的偏移不得超过10cm，拐弯处的光缆沟，应符合光缆最小曲率半径的规定。

光缆的种类1、按敷设方式分有：自承重架空光缆，管道光缆，铠装地埋光缆和海底光缆。2、按光缆结构分有：束管式光缆，层绞式光缆，紧抱式光缆，带式光缆，非金属光缆和可分支光缆。3、按用途分有：长途通讯用光缆、短途室外光缆、混合光缆和建筑物内用光缆。希望我的回答可以帮到您。
