先由规划设计院根据海洋局提供的洋流、海底地形资料，选择相对平缓的路由，提出设计方案，报相关省海洋局(厅)批复，如果跨省要国家海洋局批复，施工由登陆站开始，用拖轮龙门吊逐段铺放专门的海底光缆，在船上熔接后，用专用海底水泥铸件放到海底。

按照这些特定的要求，海底光缆的基本结构是将经过一次或两次涂层处理后的光纤螺旋地绕包在中心，加强构件(用钢丝制成)的周围。并放在专制的不锈钢管中。该管外绕高强度拱形结构的钢丝。钢丝层又包上铜管，又使得光缆铺设时不发生微／宏弯。最后挤塑外护套。

　　深海光缆的结构要求更高，光纤设在螺旋形的U形槽塑料骨架中，槽内填满油膏或弹性塑料体形成纤芯。纤芯周围用高强度的钢丝绕包，在绕包过程中要把所有缝隙都用防水材料填满，再在钢丝周围绕包一层铜带并焊接搭缝，使钢丝和铜管形成一个抗压和抗拉的联合体，这个铜管还是传送远供电流的导体。在钢丝和铜管的外面还要再加一层聚乙烯护套。这样严密多层的结构是为了保护光纤、防止断裂以及防止海水的侵入，同时也是为了在敷设和回收修理时可以承受巨大的张力和压力。即使是如此严密的防护，在80年代末还是发现过深海光缆的聚乙烯绝缘体被鲨鱼咬坏造成供电故障的实例。因此在有鲨鱼出没的地区，在海底光缆的外面还要加上钢带绕包两层后，再加一层聚乙烯外护套。

1、机器人潜下水后，通过扫描检测，找到破损海底光缆的精确位置。
　　2、机器人将浅埋在泥中的海底光缆挖出，用电缆剪刀将其切断。船上放下绳子，由机器人系在光缆一头，然后将其拉出海面。同时，机器人在切断处安置无线发射应答器。
　　3、用相同办法将另一段光缆也拉出海面。和检修电话线路一样，船上的仪器分别接上光缆两端，通过两个方向的海底光缆登陆站，检测出光缆受阻断的部位究竟在哪一端。之后，收回较长一部分有阻断部位的海底光缆，剪下。另一段装上浮标，暂时任其漂在海上。
　　4、接下来靠人工将备用海底光缆接上中美海底光缆的两个断点。连接光缆接头，可是个"技术含量"极高的活，非一般人能够胜任，必须是经过专门的严格训练、并拿到国际有关组织的执照后的人员，才能上岗操作。像这样的"接头工"，上海电信方面目前只有三四名。
　　5、备用海底光缆接上后，经反复测试，通讯正常后，就抛入海水。这时，水下机器人又要"上阵"了：对修复的海底光缆进行"冲埋"，即用高压水枪将海底的淤泥冲出一条沟，将修复的海底光缆"安放"进去。

简单来说，海底光缆铺设就是把光缆放在海底光缆敷设船上，然后船慢慢开动的同时把光缆平铺沉入海底。

具体来说，光缆铺设主要包括光缆路由勘查清理、光缆敷设和冲埋保护三个阶段。光缆敷设通常是由挖掘海底的缆线埋设机来完成的，它有点像耕田时使用的犁，由海底光缆敷设船拖曳前进，并通过工作光缆作出各种指令。其底部有几排喷水孔，作业时，每个孔同时向海底喷射出高压水柱，将海底泥沙冲开，形成光缆沟。而设备上部有一导缆孔，用来引导光缆(光缆)到光缆沟底部。
