Cisco SFP-10G-ER-S 10GBASE-ER SFP Transceiver SFP10GERS

Description:

The Cisco SFP-10G-ER-S 10GBASE-ER SFP+ Transceiver (SFP10GERS) is used in high-speed fiber optic networking systems to provide long-range 10 Gigabit Ethernet connectivity between switches, routers, and data center infrastructure devices. This SFP+ optical transceiver supports the 10GBASE-ER standard and enables reliable data transmission over single-mode fiber at extended distances, making it suitable for long-haul network links. Designed for compatibility with Cisco networking platforms, the module allows hot-swappable installation into SFP+ ports while delivering high-performance optical communication for enterprise and service provider networks. Its compact form factor and long-distance transmission capability make it an effective solution for high-speed backbone and inter-building fiber connections.

Applications:

The Cisco SFP-10G-ER-S transceiver is commonly deployed in enterprise data centers, metropolitan networks, and service provider infrastructures where long-distance 10 Gigabit Ethernet fiber connectivity is required. It is widely used to connect core switches, aggregation switches, and routers across large campus networks or between data center facilities using single-mode fiber optic cabling. The module supports high-bandwidth network backbones and long-distance fiber links that carry large volumes of network traffic between critical infrastructure systems.
