SFP-10G-ER-S — SFP+ 10 Gbps

The SFP-10G-ER-S from Cisco is an Extended Reach SFP+ 10 Gbps transceiver for single-mode fiber (SMF), compliant with the IEEE 10GBASE-ER standard. Its 40 km reach via a duplex LC (UPC) connector makes it a long-distance solution for interconnecting geographically separated sites without an optical amplifier — a characteristic that sets it apart from LR modules limited to 10 km.

This module is recommended for telecom operators, ISPs, and multi-site enterprises requiring native 10G links over long distances without signal regeneration infrastructure. The 0–70 °C operating temperature range makes it suitable for data centers and technical rooms. Genuine Cisco hardware, manufacturer warranty.
