The optical switch including a hub-side switch-port, a normal-mode switch-port, and a failover-mode switch-port. The optical coupler includes (i) a normal-mode coupler-port optically coupled to the normal-mode switch-port via a primary-path optical fiber, and (ii) a failover-mode coupler-port optically coupled to the failover-mode switch-port via a backup-path optical fiber. The optical tap detector (i) is optically coupled to the primary-path optical fiber, (ii) includes a monitor port communicatively coupled to the optical switch, and (iii) outputs a tap signal at the monitor port in response to an optical signal propagating in the primary-path optical fiber. The optical switch optically couples the hub-side switch-port to the failover-mode switch-port when the tap signal is less than a threshold value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Redundancy architectures and links","description":"An optical link redundancy architecture includes an optical switch, an optical coupler, and an optical tap detector.
