SFP-10G-ER-I — SFP+ 10 Gbps

The SFP-10G-ER-I is a Cisco 10 Gbps SFP+ module certified IEEE 10GBASE-ER, optimized for very long-reach links over single-mode fiber (SMF) up to 40 km. Its duplex LC (UPC) fiber connector and extended industrial temperature range of -40 to 85 °C make it a robust choice for demanding outdoor or mission-critical telecommunications environments.

This module is designed for integrators and operators deploying intercity backbones or long-distance datacenter interconnects where all-weather reliability is essential. The -I variant guarantees operation under severe industrial conditions where a standard commercial SFP+ would not suffice. Genuine Cisco hardware, manufacturer warranty.
