    To enhance the survivability resilience of optical fiber communication transmission network in complex adversarial environments, this paper systematically establishes a physical-logical network interdependence model and, for the first time, proposes a four-dimensional survivability resilience evaluation framework incorporating vulnerability factors, recovery factors, response time, and restoration time. A quantitative evaluation model is established using data normalization and weighted summation methods. Through empirical analysis of a regional optical fiber communication transmission network, the impacts of primary-backup route planning, response time, and recovery time on survivability resilience metrics are investigated. The results indicate that adopting a load-sharing strategy for primary-backup paths increases the survivability resilience score by 16 points, reducing the response time to 2 minutes improves the score by 5.5 points, while extending the recovery time to 60 minutes decreases the score by 5 points.
