SFP-10G-ER-S Cisco 10G SFP+ Transceiver Module 40km SMF 1550nm

The Cisco SFP-10G-ER-S transceiver is designed for environments requiring high-speed 10 Gigabit Ethernet links across extended distances. It is particularly suited for enterprise IT and data center networks where connecting equipment across campus sites or between building facilities is essential and fiber infrastructure supports single-mode connectivity.

How It's Used:

• Connecting geographically dispersed data center racks to maintain low-latency storage and compute communication.
• Extending backbone links between core switches in large enterprise campuses with fiber runs exceeding 20 kilometers.
• Supporting service provider edge routers that aggregate high-bandwidth traffic over long-haul fiber routes.
• Enabling virtualization environments to maintain high-throughput, low-latency connections between hypervisor clusters spread across multiple buildings.
• Facilitating high-capacity WAN uplinks in metropolitan area networks requiring 10G links over single-mode fiber.

By providing reliable 10G connectivity over distances up to 40 km, this module supports the scalability and performance demands of complex network topologies. It enhances operational efficiency by minimizing the need for intermediate equipment and maintaining consistent throughput in distributed infrastructure deployments.
