SFP-OC3-LR Use Case
Enterprise Data Center Interconnect with 40 km Single-Mode Fiber
In a multinational enterprise, network engineers deploy the SFP-OC3-LR-OC3 1310 nm, 40 km reach single-mode SFP in Cisco M10i and M320 chassis to establish a dedicated OC-3 (155 Mbps) link between two data centers 35 km apart. This solution delivers ultra-low latency, carrier-grade reliability, and full-duplex bandwidth for real-time database replication and disaster-recovery compliance, ensuring SLA-driven uptime and streamlined operations.
Metro Ethernet Backbone Extension for Regional ISPs
A regional Internet service provider integrates the SFP-OC3-LR-OC3 1310 nm transceiver into Cisco T640 and T320 routers to extend its metro Ethernet ring over 40 km of single-mode fiber. The plug-and-play module reduces fiber lease costs by up to 30 %, simplifies network scaling, and supports consistent OC-3 performance for business-class broadband, VoIP, and private-line services with high availability and low error rates.
Secure Remote SCADA Link for Utility Control Networks
A utility operator installs SFP-OC3-LR-OC3 modules in Cisco M7i and Reno-M120 routers to create a 40 km OC-3 single-mode fiber link for SCADA telemetry between central control and remote substations. Leveraging the 1310 nm wavelength and Cisco compatibility, the deployment guarantees deterministic data delivery, regulatory compliance, and uninterrupted monitoring of critical infrastructure, enhancing operational security and reducing downtime risks.
