摘　　要：在宽带光纤接入网项目中,提升GPON最大分路比可以减少单用户接入投资。通过分析不同类型GPON光收发合一模块的光功率预算指标,针对ODN上、下行链路衰耗不一致这一特性,提出了GPON光收发合一模块的非对称应用方案,即在GPON局端采用Class C+、用户端采用Class B+光收发合一模块进行组网,分析并验证了组网方案的可行性。该方案用较少的代价即可提升GPON所支持的最大分路比,并适用于分路比受光功率预算限制的其他PON系统。In broadband optical fiber access network project, the improvement of GPON biggest spectroscope quantity can reduce the in-vestment of single user. It analyzes the optical power budget index of different type GPON optical transceiver module, in view of the inconsistent of downlink and uplink in ODN, put forward the application scheme of asymmetric GPON optical transceiver module. It uses the class C＋in local side, class B＋in the end to form the network in the scheme. It analyzes the feasibility of network. The scheme uses less investment to improve GPON biggest shunt ratio, and it is suitable for other PON system whose optical branching is limited by the optical power budget.
