SFP-10G-ER — SFP+ 10 Gbps

The SFP-10G-ER from Cisco is an Extended Reach SFP+ 10 Gbps transceiver for single-mode fiber (SMF), compliant with the IEEE 10GBASE-ER standard. With a 40 km reach via a duplex LC (UPC) connector, it enables long-distance optical links without signal regeneration equipment, unlike the SFP-10G-ER-S which carries additional certification for certain Cisco platforms.

This transceiver suits enterprise WAN architectures and metropolitan links where distances exceed the coverage of LR modules. Typical use cases include links between urban data centers, carrier POPs, or remote industrial sites. Operating temperature range 0–70 °C. Genuine Cisco hardware, manufacturer warranty.
