SFP-OC3-IR1 Use Case
Metropolitan Data Center Interconnect with SFP-OC3-IR1-SFP OC-3/STM-1 Intermediate-Reach
In a regional ISP deployment, network engineers use the SFP-OC3-IR1-SFP OC-3/STM-1 Intermediate-Reach module to link two data centers across 8 km of single-mode fiber, providing a dedicated 155 Mbps OC-3 transport. The result is low-latency, high-availability replication for critical applications, optimized power consumption, and predictable OPEX for long-haul campus networks.
Financial Branch Office Fiber Link Using SFP-OC3-IR1 for Secure 155 Mbps Backup
A multinational bank equips its suburban branch with the SFP-OC3-IR1-SFP OC-3/STM-1 Intermediate-Reach transceiver to extend its secure WAN over existing dark fibers up to 10 km. This solution delivers constant 155 Mbps throughput with hardware-level encryption support, ensuring real-time transaction syncing and regulatory compliance while minimizing capital expenditure on new infrastructure.
Cable TV Headend to Remote Node Video Distribution via SFP-OC3-IR1
A cable MSO integrates the SFP-OC3-IR1-SFP OC-3/STM-1 Intermediate-Reach module into its headend switches to distribute 155 Mbps MPEG streams to suburban remote nodes over 6 km of fiber. This approach guarantees carrier-grade QoS, reduces signal regeneration points, and simplifies service turn-up—resulting in higher uptime, lower maintenance costs, and improved subscriber satisfaction.
