Cisco SFP-10G-ER 10G SFP+ Transceiver Module

What It Is

The Cisco SFP-10G-ER is a 10GBASE-ER SFP+ transceiver module designed for enterprise local area network (LAN) deployments. This hot-swappable optical module enables 10 Gigabit Ethernet connectivity over extended reach distances, operating in accordance with the 10GBASE-ER standard. It is a dedicated Cisco-branded component intended for use in compatible SFP+ ports across supported Cisco switching and routing platforms.

Configuration & Options

• Included: Single Cisco SFP-10G-ER transceiver module
• Compatibility: Intended for use in Cisco SFP+ ports on supported switches and routers
• Optical Interface: Standard LC-type duplex connector (implied by 10GBASE-ER form factor)
• Interchangeability: This module is a distinct SKU within the broader Cisco 10GBASE SFP+ ordering matrix; other models in the series (e.g., SFP-10G-BX40D-I=, SFP-10G-BXU-I=) serve different reach or bidirectional configurations

Operating Conditions

The Cisco SFP-10G-ER is deployed in enterprise LAN environments where extended reach between network nodes exceeds typical short-range limits. It is suited for campus backbone links, inter-building connections, and other structured cabling scenarios requiring 10 Gbps throughput over single-mode fiber. The module operates within standard SFP+ environmental specifications for temperature and humidity as defined by Cisco for indoor equipment installations.
