    • A method for facilitating passive optical network fiber protection comprises facilitating transmission of bi-directional traffic utilizing a first optical fiber connected between a first port interface of an optical line termination and a first upstream fiber termination of a splitter, and facilitating fiber protection functionality utilizing a second optical fiber connected between a second port interface of the optical line termination and a second upstream fiber termination of the splitter fiber. The fiber protection functionality includes monitoring reception of traffic transmitted on the first optical fiber from at least one optical network termination unit, maintaining the second one of the port interfaces in an inactive state while transmission of the traffic is being successfully performed utilizing the first optical fiber; determining when a traffic error condition exists with respect to transmission of the traffic on the first optical fiber and facilitating transmission of the traffic on the second optical fiber after determining that the traffic error condition exists and after activating the second one of the port interfaces. Facilitating transmission of the traffic on the second optical fiber includes deactivating the first one of the port interfaces, activating the second one of the port interfaces and redirecting the traffic from the first one of the port interfaces to the second one of the port interfaces.
    • 一种促进无源光网络光纤保护的方法包括利用连接在光线路终端的第一端口接口和分离器的第一上游光纤终端之间的第一光纤来促进双向业务的传输,并且利用光纤保护功能 第二光纤连接在光线路终端的第二端口接口和分离光纤的第二上游光纤终端之间。 光纤保护功能包括监视从至少一个光网络终端单元监测在第一光纤上传输的流量的接收状态,同时使用第一光纤成功执行业务的传输,将第二个端口接口保持在非活动状态 ; 确定关于第一光纤上的业务传输何时存在流量错误状况,并且在确定存在业务错误条件之后以及在激活第二个端口接口之后促进业务在第二光纤上的传输。 促进在第二光纤上的业务的传输包括去激活端口接口中的第一端口,激活端口接口中的第二端口,并将业务从第一端口接口重定向到第二端口接口。
