Cisco SFP-10G-ER Transceiver Module
The Cisco SFP-10G-ER is a 10 Gigabit Ethernet SFP+ optical transceiver designed for extended-reach connectivity over single-mode fiber (SMF). It supports the 10GBASE-ER standard and operates in the 1550nm optical window.
With support for optical links of up to 40km over G.652 single-mode fiber, the Cisco SFP-10G-ER is suitable for enterprise backbone networks, metropolitan networks, data center interconnects, service-provider infrastructure, and other long-distance 10GbE applications.

10GBASE-ER Extended-Reach Connectivity
The Cisco SFP-10G-ER is designed for extended-reach 10 Gigabit Ethernet applications. Its 1550nm optical transmission provides substantially greater reach than short-reach 10GBASE-SR and standard 10GBASE-LR modules.
1550nm Single-Mode Fiber Operation
The transceiver operates over G.652 single-mode fiber in the 1550nm wavelength range. This makes it suitable for longer optical paths where 10km LR optics are insufficient.
40km Optical Reach
Cisco specifies a maximum cable distance of approximately 40km for the SFP-10G-ER. For long links, actual performance depends on fiber attenuation, dispersion, connector losses, splice losses, and the complete optical link budget. Cisco notes that links beyond certain distances may require verification of cable characteristics and loss values.
Duplex LC Fiber Interface
The SFP-10G-ER uses a duplex LC/PC optical connector with separate transmit and receive paths. It is designed for standard duplex single-mode fiber cabling used in long-distance 10GbE deployments.
Network Applications
- 10 Gigabit Ethernet backbone links
- Enterprise WAN and campus backbone connectivity
- Data center interconnects
- Metropolitan-area network connections
- Service-provider network infrastructure
- Long-distance switch-to-switch links
- Core and distribution network connectivity
Compatibility
The Cisco SFP-10G-ER is designed for compatible Cisco equipment equipped with SFP+ interfaces. Cisco documentation lists the module for 10GBASE-ER operation over G.652 SMF with a 40km reach. Always verify the exact Cisco hardware model, software release, and supported transceiver list before deployment.
Optical Link Considerations
For extended-distance installations, optical link engineering is important. Fiber attenuation, chromatic dispersion, connector losses, splice losses, and receive-power limits should be evaluated before deploying a 40km SFP-10G-ER link. Cisco documentation also notes that distances beyond 30km require verification of cable characteristics, particularly cable loss.
