Abstract: An optical system is provided that converts optical signals received over an optical trunk from a first optical switch to client optical signals intended for a second optical switch. The first and second optical switches operate in accordance with a Fiber Channel (FC) protocol. An interruption of the optical signals on the optical trunk is detected. Responsive to the interruption, a Not Operational State (NOS) message sent to the second optical switch is delayed so as to delay triggering of an FC link initialization in the second optical switch. While the NOS message is delayed, idle messages are sent to the second optical switch.

Abstract translation: 提供了一种光学系统，其将通过光中继线接收的光信号从第一光开关转换成用于第二光开关的客户端光信号。 第一和第二光开关根据光纤通道（FC）协议进行操作。 检测到光中继线上光信号的中断。 响应于中断，发送到第二光开关的非操作状态（NOS）消息被延迟，以便延迟触发第二光开关中的FC链路初始化。 当NOS消息被延迟时，空闲消息被发送到第二光交换机。
