plc(光分路器)技术发展情况

     低成本、高可靠性是ftth工程中对光分路器件的基本要求。光通信用光分路器从技术工艺上主要可以分为光纤熔融拉锥型和平面集成光波导型两种。

     光纤熔融拉锥技术是制作2´2光分路器为成熟的技术，光分路器目前主要是以全光纤型光分路器为主，其主要特点是：技术成熟，与光纤的连接方便，插入损耗小。但随着功分路数的增加，如1×8以上的光功分路器体积大，效率低，成本高，而且分光均匀性较差。此外基于融熔拉锥技术的光纤光分路器通带等特性方面有很大局限性。

     plc基于平面技术的集成光学器件。与传统的分立式器件不同他采用的是半导体工艺制作，能够把不同功用的光学元件集成到一块芯片上，是实现光电器件集成化、规模化、小型化的基础工艺技术。与熔融拉锥技术相比，平面波导技术具有性能稳定、成本低廉、适于规模化生产等显著特点。所以，今后在光纤到户系统中将不再使用光纤融熔拉锥光功分器件，而平面波导为高性能、低成本接入网用光器件的生产提供了一条有效的途径。
