Industrial M5502R-1000SX-F Multilayer Network Switch

The M5502R-1000SX-F is a two-port multilayer (Layer 3) fiber module for Avaya Cajun/Lucent P550R systems, delivering integrated routing with two 1 Gbps 1000BASE-SX interfaces. It uses short-wavelength SX fiber (850 nm) for its links, making it suitable for fiber backbone connections and distribution links within the P550R platform. Specifically described as a 2-port 1000BASE-SX module for the P550R family with Layer 3 routing, it augments Avaya’s modular networking by adding dual fiber ports that participate in routed paths alongside switching. The M5502R-1000SX-F is listed in distributor catalogs and Avaya/Lucent documentation as the two-port SX fiber module intended for P550R L3 deployments, reflecting its place in the Cajun lineage of Avaya network equipment.
