摘　　要：运营商4G/5G网络的建设、政企客户的快速增长及快速开通业务的要求,一方面对光纤资源占用量明显增大,对现有承载网造成极大的压力;另一方面,业务开通时限要求快速。如何实现低成本、快速接入、提升投资有效性已成为当前各运营商面临的主要问题。而无源波分复用技术恰好符合解决现有光纤资源不足、再次敷设光缆协调难、建设投资大、光缆重复建设、建设工期长等一系列问题,采用无源波分复用技术可大大降低建设投资,最终达到光纤资源利用率最大化。The construction of operator 4 G/5 G Network,the rapid growth of enterprise customers and the requirement of rapid opening of business,the consumption of optical fiber resources has increased significantly,the existing bearing network has caused great pressure,how to achieve low cost,fast access,improve the effectiveness of investment has become the main problem faced by operators at present.The passive wavelength division technology is in line with the problems of solving the shortage of existing optical fiber resources,the difficulty of laying the fiber optic cable again,the construction investment,the repeated construction of optical cable,the long construction period,and so on,the use of passive wavelength division multiplexing technology can greatly reduce the construction investment,and finally achieve the maximization of optical fiber resource utilization.
