Cisco 10GbE 10GBase-ER 1550nm 40km LC SFP+ Transceiver

The Cisco SFP-10G-ER= is a hot-swappable SFP+ transceiver that delivers 10 Gigabit Ethernet links over single-mode fiber at distances of up to 40 kilometers. It operates at a 1550 nm wavelength and uses a duplex LC connector, making it straightforward to integrate with existing fiber runs.

Built on the IEEE 802.3ae 10GBase-ER specification, the module sustains full 10 Gbps throughput while keeping latency low and power usage in check. Installation is simple: insert the module into a compatible Cisco switch, router, or network interface card, connect the fiber pair, and the link comes up without additional configuration.

The extended reach makes this optic valuable for campus backbones, metropolitan access loops, and long-haul connections between data centers. It lets enterprises extend high-speed services between buildings, gives service providers a reliable way to aggregate remote sites, and helps colocation facilities link redundant infrastructure without the cost of optical repeaters.

Because the module follows Cisco’s SFP+ guidelines and the IEEE standard, it works across a wide range of Cisco platforms. That broad compatibility protects existing investments and allows seamless upgrades as bandwidth demands grow.
