Features:

• Extended Range (ER): The SFP-10G-ER module enables 10G Ethernet communication over distances up to 40 km, using a wavelength of 1550 nm. This makes it suitable for long-haul applications and inter-building connectivity.
• Compact Form Factor: Like other modules in the Cisco SFP+ family, the SFP-10G-ER has a compact design. This allows for greater port density in network switches and routers. Which is critical in high-performance, high density networking environments.
• Hot Swappable: The module is hot-swappable, meaning it can be inserted or replaced in an Ethernet SFP+ port on a Cisco switch or router without powering down the device. This minimizes network downtime during upgrades or maintenance.
• Investment Protection: The Cisco SFP-10G-ER module supports Cisco’s “pay-as-you-grow” model, providing flexibility to scale the network as needed. While protecting existing investments in network infrastructure.
• High Compatibility: The SFP-10G-ER is compatible with a variety of Cisco devices. Hence ensuring seamless integration and reliability in existing network setups.
