为实现岸端基站与水下设备之间的实时数据传输和电能传输，必须通过水下光电分离器将光电复合海缆中的通信光纤和供电导体在水下进行分离后接入主接驳盒中，进而再通过水密电缆将主接驳盒与次级接驳盒进行连接。设计的水下光电分离器一般要求易于安装、应用在不同海洋工程装备上的兼容性好、长时间运行时稳定性好。
目前海底光缆光电分离器技术由于结构和功能设计欠缺，存在如下不足：(1)光电复合缆与光电分离器之间机械连接固定方式一般采用压铠自锁紧方式，只能适用于有铠装钢丝层的光电复合缆，而不适用于无铠装钢丝的光电复合缆；(2)现有水下光电分离器不具备光电转换功能，只能局限在实现通信光纤和供电导体经物理分离后，再用水密光插拔连接器和水密电插拔连接器与其它水下设备连接起来；(3)而相对于水密电插拔连接器而言，水密光插拔连接器技术尚不成熟，可靠性偏低，且价格昂贵，此外，水密光插拔连接器中光插芯数有限，一般低于8芯，无法满足大容量光纤的光电复合缆与其它水下装置之间的连接需求；(4)光电分离器缺乏有效的耐海水腐蚀保护措施，整体耐海水腐蚀性差，导致使用寿命短。
