SFP-10G-BX40D-I Use Case
Metro Ethernet Service Delivery over 40 km Single-Fiber
Internet and managed-service providers deploy the SFP-10G-BX40D-I-SFP+ bidirectional transceiver on a single strand of dark fiber to deliver 10 Gbps downstream and upstream Ethernet services up to 40 km. This solution slashes fiber-lease costs, accelerates turn-up times, and guarantees carrier-grade performance for enterprise customers, driving higher margins and service-level compliance.
Data Center Interconnect for Remote Replication
Enterprises leverage the SFP-10G-BX40D-I-SFP+ module to bridge geographically dispersed data centers over a single-fiber 40 km span, enabling high-throughput VM migration, real-time backup, and disaster-recovery orchestration. The bidirectional design reduces fiber count by 50%, simplifies network architecture, and ensures deterministic latency for mission-critical applications.
5G Cell-Site Backhaul on Existing Fiber Infrastructure
Telecom operators integrate the SFP-10G-BX40D-I-SFP+ transceiver into their aggregation switches to extend 10 Gbps downstream fronthaul and backhaul links from 5G cell sites up to 40 km away. This single-fiber solution optimizes capital expenditure, speeds deployment, and delivers low-latency, high-capacity connectivity for demanding mobile-broadband and IoT services.
