Core Product Positioning
The Cisco SFP-10G-ER is a hot‑swappable commercial-grade SFP+ transceiver compliant with IEEE 802.3ae 10GBASE-ER. It delivers wire-speed 10-Gigabit Ethernet transmission over standard single-mode fiber for long-distance campus interconnections, metro networking, cross-building data center links and carrier enterprise point-to-point circuits. Integrated DOM/DDM digital diagnostics support real-time monitoring of internal optical parameters. This module supports Fibre Channel over Ethernet (FCoE) for converged data and storage networking.
2. Hardware & Software Compatibility
Supported Host Platforms
Cisco Catalyst 3650, 3850, 4500-X, 6500, 6800, 9200, 9300 Series; Nexus 2000, 3000, 5000, 9000 Series Switches; ASR 1000, ASR 900 Series Routers; UCS Fabric Interconnects; MDS 9000 Storage Switches and Firepower appliances equipped with SFP+ ports.
Supported IOS / IOS XE / NX-OS Versions
All mainstream Cisco operating system releases supporting SFP+ MSA specification and SFF‑8472 DOM diagnostic functions.
Supported Fiber Type
Single‑Mode Fiber (SMF) G.652 (9/125μm) only; incompatible with multimode fiber.
Unsupported Platforms
