Novel self-healing configurations for broadband fiber-based access network architectures

Summary form only given. Unprotected hybrid fiber/coax (HFC) and fiber supertrunk architectures are considered baseline cases for this study. These architectures are modeled in an access area having a center horizontal mainleg street and 12 vertical sideleg streets, which contain a total of 384 living units. In previous work, fiber-segment protection of two narrowband fiber-to-the-curb architectures were considered; here we not only consider HFC and supertrunk fiber-segment protection, but also investigate the more challenging problem of HFC coaxial-segment and 1:16 optical equipment protection.
