    • Extender apparatus for an optical network includes first and second extender units having an network-facing port for connection to a backhaul fiber and a subscriber-facing port for connection to a feeder fiber. Each extender unit includes a gain assembly and is operable selectively either in an enabled state, in which the gain assembly amplifies a signal received at either port of the extender unit and couples it to the other port of the extender unit, or in a disabled state, in which the gain assembly blocks coupling of a signal from either port of the extender unit to the other port of the extender unit. A failover unit is operable when the first extender unit is in the enabled state and the second extender unit is in the disabled state to detect occurrence of at least one fault condition in the first extender unit. The failover unit is responsive to the fault condition in the first extender unit to switch the first extender unit to the disabled state and the second extender unit to the enabled state.
    • 用于光网络的扩展器装置包括第一和第二扩展器单元,其具有用于连接到回程光纤的面向网络的端口和用于连接到馈线光纤的用户面向端口。 每个扩展器单元包括增益组件,并且可选地处于使能状态,其中增益组件放大在扩展器单元的任一端口处接收的信号并将其耦合到扩展器单元的另一端口,或处于禁用状态 ,其中增益组件阻止将信号从扩展器单元的任一端口耦合到扩展器单元的另一端口。 当第一扩展器单元处于使能状态并且第二扩展器单元处于禁用状态以检测第一扩展器单元中的至少一个故障状况的发生时,故障转移单元可操作。 故障切换单元响应于第一扩展器单元中的故障状况,将第一扩展器单元切换到禁用状态,将第二扩展器单元切换到启用状态。
